The son of a distinguished Parisian instrument maker, Charles Chevalier supplied equipment to all the major photographic pioneers of the period. He sold a camera obscura to Niepce de St Victor as early as 1826 and was largely responsible for bringing Niepce de St Victor and Daguerre together. Chevalier was one of the first opticians to design lenses specifically for photographic use; the first photographic camera to be offered for sale to the public, the Giroux daguerreotype camera of 1839, was in fact fitted with a Chevalier achromatic lens. Chevalier also supplied lenses, equipment and examples of daguerreotypes to Talbot in England. In 1841 Chevalier was awarded first prize in a competition for the improvement of photographic lenses, sponsored by the Société d'Encouragement of Paris. Contemporary opinion, however, favoured the runner-up, the Petzval Portrait lens by Voigtländer of Vienna, and Chevalier subsequently became embroiled in an acrimonious dispute which did him little credit. It did not stop him designing lenses, and he went on to become an extremely successful supplier of quality daguerreotype equipment. He was a founder member of the Société Héliographique in 1851.

John Coster, son of an iron-forge manager in the Forest of Dean, by the age of 38 was at Bristol, where he was "chief agent and sharer therein" in the new lead-smelting methods using coal fuel. In 1685 the work, under Sir Clement Clerke, was abandoned because of patent rights claimed by Lord Grandison, who financed of earlier attempts. Clerke's business turned to the coal-fired smelting of copper under Coster, later acknowledged as responsible for the subsequent success through using an improved reverberatory furnace which separated coal fume from the ores being smelted. The new technique, applicable also to lead and tin smelting, revitalized copper production and provided a basis for new British industry in both copper and brass manufacture during the following century. Coster went on to manage a copper-smelting works, and by the 1690s was supplying Esher copper-and brass-works in Surrey from his Redbrook, Gloucestershire, works on the River Wye. In the next decade he extended his activities to Cornish copper mining, buying ore and organizing ore sales, and supplying the four major copper and brass companies which by then had become established. He also made copper goods in additional water-powered rolling and hammer mills acquired in the Bristol area. Coster was ably assisted by three sons; of these, John and Robert were mainly active in Cornwall. In 1714 the younger John, with his father, patented an "engine for drawing water out of deep mines". The eldest son, Thomas, was more involved at Redbrook, in South Wales and the Bristol area. A few years after the death of his father, Thomas became partner in the brass company of Bristol and sold them the Redbrook site. He became Member of Parliament for Bristol and, by then the only surviving son, planned a large new smelting works at White Rock, Swansea, South Wales, before his death in 1734. Partners outside the family continued the business under a new name.

In 1912 Donald Douglas went to the Massachusetts Institute of Technology to study aeronautical engineering. After graduating in this relatively new subject he joined the Glenn L.Martin Company as Chief Engineer. In 1920 he founded the Davis-Douglas Company in California to build an aircraft capable of flying across America non-stop: unfortunately, the Cloudster failed to achieve its target. Douglas reorganized the company in 1921 as the Douglas Company (later it became the Douglas Aircraft Company). In 1924 a team of US Army personnel made the first round-the-world flight in specially designed Douglas World Cruisers, a feat which boosted Douglas's reputation considerably. This reputation was further enhanced by his airliner, designed in 1935, that revolutionized air travel: the Douglas Commercial 3, or DC-3, of which some 13,000 were built. A series of piston-engined airliners followed, culminating in the DC-7. Meanwhile, in the military field, Douglas aircraft played a major part in the Second World War. In the jet age Douglas continued to produce a wide range of successful civil and military aircraft, and the company also moved into the rocket and guided missile business. In 1966 Donald W. Douglas was still Chairman of the company, with Donald W.Douglas Jr as President. In 1967 the company merged with the McDonnell Aircraft Company to become the giant McDonnell Douglas Corporation.

Griffith was very much a "boffin", for he was a quiet, thoughtful man who shunned public appearances, yet he produced many revolutionary ideas. During the First World War he worked at the Royal Aircraft Factory, Farnborough, where he carried out research into structural analysis. Because of his use of soap films in solving torsion problems, he was nicknamed "Soap-bubble".

During the 1920s Griffith carried out research into gas-turbine design at the Royal Aircraft Establishment (RAE; as the Royal Aircraft Factory had become). In 1929 he made proposals for a gas turbine driving a propeller (a turboprop), but the idea was shelved. In the 1930s he was head of the Engine Department of the RAE and developed multi-stage axial compressors, which were later used in jet engines. This work attracted the attention of E.W. (later Lord) Hives of Rolls-Royce who persuaded Griffith to join Rolls-Royce in 1939. His first major project was a "contra-flow" jet engine, which was a good idea but a practical failure. However, Griffith's axial-flow compressor experience played an important part in the success of Rolls-Royce jet engines from the Avon onwards. He also proposed the bypass principle used for the Conway.

Griffith experimented with suction to control the boundary layer on wings, but his main interest in the 1950s centred on vertical-take-off and -landing aircraft. He developed the remarkable "flying bedstead", which consisted of a framework (the bedstead) in which two jet engines were mounted with their jets pointing downwards, thus lifting the machine vertically. It first flew in 1954 and provided much valuable data. The Short SC1 aircraft followed, with four small jets providing lift for vertical take-off and one conventional jet to provide forward propulsion. This flew successfully in the late 1950s and early 1960s. Griffith proposed an airliner with lifting engines, but the weight of the lifting engines when not in use would have been a serious handicap. He retired in 1960.

King was educated at the High School of Glasgow, and then served an apprenticeship with the Port Glasgow shipyard of Russell \& Co. This was followed by experience in drawing offices in Port Glasgow, Hull and finally in Belfast, where he was responsible for the separate White Star Line drawing office of Harland \& Wolff Ltd, which was then producing the plans for the Atlantic passenger liners Majestic and Teutonic. Following certain unpopular government shipping enactments in 1890, a protest from shipbuilders and shipowners in Ireland, Liverpool and the West of Scotland led to the founding of a new classification society to compete against Lloyd's Register of Shipping. It became known as the British Corporation Register and had headquarters in Glasgow. King was recruited to the staff and by 1903 had become Chief Surveyor, a position he held until his retirement thirty-seven years later. By then the Register was a world leader, with hundreds of thousands of tons of shipping on its books; it acted as consultant to many governments and international agencies. Throughout his working life, King did everything in his power to quantify the risks and problems of ship operation: his contribution to the Load Lines Convention of 1929 was typical, and few major enactments in shipping were designed without his approval. During the inter-war period the performance of the British Corporation outshone that of all rivals, for which King deserved full credit. His especial understanding was for steel structures, and in this respect he ensured that the British Corporation enabled owners to build ships of strengths equal to any others despite using up to 10 per cent less steel within the structure. In 1949 Lloyd's Register of Shipping and the British Corporation merged to form the largest and most influential ship classification society in the world.

Lithgow attended Glasgow Academy and then spent a year in Paris. In 1901 he commenced a shipyard apprenticeship with Russell \& Co., where his father, William Lithgow, was sole proprietor. For years Russell's had topped the Clyde tonnage output and more than once had been the world's leading yard. Along with his brother Henry, Lithgow in 1908 was appointed a director, and in a few years he was Chairman and the yard was renamed Lithgows Ltd. By the outbreak of the First World War the Lithgow brothers were recognized as good shipbuilders and astute businessmen. In 1914 he joined the Royal Artillery; he rose to the rank of major and served with distinction, but his skills in administration were recognized and he was recalled home to become Director of Merchant Shipbuilding when British shipping losses due to submarine attack became critical. This appointment set a pattern, with public duties becoming predominant and the day-to-day shipyard business being organized by his brother. During the interwar years, Lithgow served on many councils designed to generate work and expand British commercial interests. His public appointments were legion, but none was as controversial as his directorship of National Shipbuilders Security Ltd, formed to purchase and "sterilize" inefficient shipyards that were hindering recovery from the Depression. To this day opinions are divided on this issue, but it is beyond doubt that Lithgow believed in the task in hand and served unstintingly. During the Second World War he was Controller of Merchant Shipbuilding and Repairs and was one of the few civilians to be on the Board of Admiralty. On the cessation of hostilities, Lithgow devoted time to research boards and to the expansion of the Lithgow Group, which now included the massive Fairfield Shipyard as well as steel, marine engineering and other companies.

Throughout his life Lithgow worked for the Territorial Army, but he was also a devoted member of the Church of Scotland. He gave practical support to the lona Community, no doubt influenced by unbounded love of the West Highlands and Islands of Scotland.

Messerschmitt studied engineering at the Munich Institute of Tchnology and obtained his degree in 1923. By 1926 he was Chief Designer at the Bayerische Flugzeugwerke in Augsburg. Due to the ban on military aircraft in Germany following the First World War, his early designs included gliders, light aircraft, and a series of high-wing airliners. He began to make a major impact on German aircraft design once Hitler came to power and threw off the shackles of the Treaty of Versailles, which so restricted Germany's armed forces. In 1932 he bought out the now-bankrupt Bayerische Flugzeugwerke, but initially, because of enmity between himself and the German aviation minister, was not invited to compete for an air force contract for a single-engined fighter. However, in 1934 Messerschmitt designed the Bf 108 Taifun, a small civil aircraft with a fighter-like appearance. This displayed the quality of his design and the German air ministry was forced to recognize him. As a result, he unveiled the famous Bf 109 fighter which first flew in August 1935; it was used during the Spanish Civil War in 1936–9, and was to become one of the foremost combat aircraft of the Second World War. In 1938, after several name changes, the company became Messerschmitt Aktien-Gesellschaft (and hence a change of prefix from Bf to Me). During April 1939 a Messerschmitt aircraft broke the world air-speed record at 755.14 km/h (469.32 mph): it was entered in the FAI records as a Bf 109R, but was more accurately a new design designated Me 209V-1.

During the Second World War, the 5/70P was progressively improved, and eventually almost 35,000 were built. Other successful fighters followed, such as the twin-engined Me 110 which also served as a bomber and night fighter. The Messerschmitt Me 262 twin-engined jet fighter, the first jet aircraft in the world to enter service, flew during the early years of the war, but it was never given a high priority by the High Command and only a small number were in service when the war ended. Another revolutionary Messerschmitt AG design was the Me 163 Komet, the concept of Professor Alexander Lippisch who had joined Messerschmitt's company in 1939; this was the first rocket-propelled fighter to enter service. It was a small tailless design capable of 880 km/hr (550 mph), but its duration under power was only about 10 minutes and it was very dangerous to fly. From late 1944 onwards it was used to intercept the United States Air Force bombers during their daylight raids. At the other end of the scale, Messerschmitt produced the Me 321 Gigant, a huge transport glider which was towed behind a flight of three Me 110s. Later it was equipped with six engines, but it was an easy target for allied fighters. This was a costly white elephant, as was his high-speed twin-engined Me 210 fighter-bomber project which nearly made his company bankrupt. Nevertheless, he was certainly an innovator and was much admired by Hitler, who declared that he had "the skull of a genius", because of the Me 163 Komet rocket-powered fighter and the Me 262.

At the end of the war Messerschmitt was detained by the Americans for two years. In 1952 Messerschmitt became an aviation adviser to the Spanish government, and his Bf109 was produced in Spain as the Hispano Buchon for a number of years and was powered by Rolls-Royce Merlin engines. A factory was also constructed in Egypt to produce aircraft to Messerschmitt's designs. His German company, banned from building aircraft, produced prefabricated houses, sewing machines and, from 1953 to 1962, a series of bubble-cars: the KR 175 (1953–55) and the KR 200 (1955–62) were single-cylinder three-wheeled bubble-cars, and the Tiger (1958–62) was a twin-cylinder, 500cc four-wheeler. In 1958 Messerschmitt resumed aircraft construction in Germany and later became the Honorary Chairman of the merged Messerschmitt-Bölkow-Blohm company (now part of the Franco-German Eurocopter company).

Paul was educated at the City of London School and Finsbury Technical College. He worked first for a short time in the Bell Telephone Works in Antwerp, Belgium, and then in the electrical instrument shop of Elliott Brothers in the Strand until 1891, when he opened an instrument-making business at 44 Hatton Garden, London. He specialized in the design and manufacture of electrical instruments, including the Ayrton Mather galvanometer. In 1902, with a purpose-built factory, he began large batch production of his instruments. He also opened a factory in New York, where uncalibrated instruments from England were calibrated for American customers. In 1903 Paul introduced the Unipivot galvanometer, in which the coil was supported at the centre of gravity of the moving system on a single pivot. The pivotal friction was less than in a conventional instrument and could be used without accurate levelling, the sensitivity being far beyond that of any pivoted galvanometer then in existence.

In 1894 Paul was asked by two entrepreneurs to make copies of Edison's kinetoscope, the pioneering peep-show moving-picture viewer, which had just arrived in London. Discovering that Edison had omitted to patent the machine in England, and observing that there was considerable demand for the machine from show-people, he began production, making six before the end of the year. Altogether, he made about sixty-six units, some of which were exported. Although Edison's machine was not patented, his films were certainly copyrighted, so Paul now needed a cinematographic camera to make new subjects for his customers. Early in 1895 he came into contact with Birt Acres, who was also working on the design of a movie camera. Acres's design was somewhat impractical, but Paul constructed a working model with which Acres filmed the Oxford and Cambridge Boat Race on 30 March, and the Derby at Epsom on 29 May. Paul was unhappy with the inefficient design, and developed a new intermittent mechanism based on the principle of the Maltese cross. Despite having signed a ten-year agreement with Paul, Acres split with him on 12 July 1895, after having unilaterally patented their original camera design on 27 May. By the early weeks of 1896, Paul had developed a projector mechanism that also used the Maltese cross and which he demonstrated at the Finsbury Technical College on 20 February 1896. His Theatrograph was intended for sale, and was shown in a number of venues in London during March, notably at the Alhambra Theatre in Leicester Square. There the renamed Animatographe was used to show, among other subjects, the Derby of 1896, which was won by the Prince of Wales's horse "Persimmon" and the film of which was shown the next day to enthusiastic crowds. The production of films turned out to be quite profitable: in the first year of the business, from March 1896, Paul made a net profit of £12,838 on a capital outlay of about £1,000. By the end of the year there were at least five shows running in London that were using Paul's projectors and screening films made by him or his staff.

Paul played a major part in establishing the film business in England through his readiness to sell apparatus at a time when most of his rivals reserved their equipment for sole exploitation. He went on to become a leading producer of films, specializing in trick effects, many of which he pioneered. He was affectionately known in the trade as "Daddy Paul", truly considered to be the "father" of the British film industry. He continued to appreciate fully the possibilities of cinematography for scientific work, and in collaboration with Professor Silvanus P.Thompson films were made to illustrate various phenomena to students.

Paul ended his involvement with film making in 1910 to concentrate on his instrument business; on his retirement in 1920, this was amalgamated with the Cambridge Instrument Company. In his will he left shares valued at over £100,000 to form the R.W.Paul Instrument Fund, to be administered by the Institution of Electrical Engineers, of which he had been a member since 1887. The fund was to provide instruments of an unusual nature to assist physical research.

From 1795 Rondelet was Professor at the Ecole Centrale des Travaux Publics and while there was responsible for a major treatise on building construction: this was his Traité théorique et pratique de l'art de bâtir, published in four volumes in 1802–17. From 1806 he taught at the Ecole Spéciale d'Architecture, which was soon afterwards merged with the Ecole Polytechnique. It was when Rondelet took over the work of com-pleting the Panthéon in Paris, after the death of Jacques-Germain Soufflot, that he had the opportunity of putting some of his particular structural ideas into practice. In 1755 the King had appointed Soufflot architect of the great new church to be dedicated to the patron saint of the city, Sainte Geneviève. In this neo-classical structure based upon Greek cross plan, Soufflot intended four slender piers, each encased in three engaged columns, to support the pendentives for the dome to rise over the crossing. It was a fine and elegant building on a large scale, but by the early nineteenth century, when the church had become a pantheon, cracks were appearing in the masonry. When Rondelet succeeded as architect after Soufflot's death, he strengthened and enlarged the piers, employing a faced concrete structure reinforced with metal. He used a metalreinforced mortar with rubble aggregate.

In 1722, employed as an apothecary's assistant, he studied surgery and especially diseases of the eye under Cheselden at St Thomas's Hospital, London. He returned to Norwich to practise, but in 1727 he assumed the role of itinerant surgeon oculist, with a particular reputation for putting eyes straight; at first he covered the major part of the British Isles and then he extended his activities to Europe.

He obtained MDs from Basle in 1733, and from Liège and Cologne in 1734. In 1736 he was appointed Oculist to George II. It is likely that he was responsible for Johann Sebastian Bach's blindness, and Gibbon was one of his patients. The subject of considerable obloquy on account of his self-advertisement in the crudest and most bombastic terms, it is none the less certain that he had developed a technique, probably related to couching, which was considerably in advance of that of other practitioners and at least offered a prospect of assistance where none had been available.

Dr Johnson declared him "an instance of how far impudence will carry ignorance". Without justification, he styled himself "Chevalier". He is said, not improbably having regard to his age, to have become blind himself later in life. His son carried on his practice.

From an old mining family in the Saxon coalfields, Wolf was aware from his youth of the urgent demand for a miner's lamp which would provide adequate light but not provoke firedamp explosions. While working as an engineer in Zwickau, Wolf spent his spare time conducting experiments for such a lamp. The basic concept of his invention was the principle that dangerous concentrations of methane and air would not explode within a small pipe; this had been established almost seventy years earlier by the English chemist Humphrey Davy. By combining and developing certain devices designed by earlier inventors, in 1883 Wolf produced a prototype with a glass cylinder, a primer fixed inside the lamp and a magnetic lock. Until the successful application of electric light, Wolfs invention was the safest and most popular mining safety lamp. Many earlier inventions had failed to address all the problems of lighting for mines; Davy's lamp, for example, would too quickly become sooty and hot. As Wolfs lamp burned petroleum spirit, at first it was mistrusted outside Saxony, but it successfully passed the safety tests in all the leading coal-producing countries at that time. As well as casting a safe, constant light, the appearance of the cap flame could indicate the concentration of fire-damp in the air, thus providing an additional safety measure. Wolfs first patent was soon followed by many others in several countries, and underwent many developments. In 1884 Heinrich Friemann, a merchant from Eisleben, invested capital in the new company of Friemann and Wolf, which became the leading producer of miners' safety lamps. By 1914 they had manufactured over one million lamps, and the company had branches in major mining districts worldwide.

   1) There Are Ideas That Have Their Own True and Immutable Nature

   And what I believe to be more important here is that I find in myself an infinity of ideas of certain things which cannot be assumed to be pure nothingness, even though they may have perhaps no existence outside of my thought. These things are not figments of my imagination, even though it is within my power to think of them or not to think of them; on the contrary, they have their own true and immutable natures. Thus, for example, when I imagine a triangle, even though there may perhaps be no such figure anywhere in the world outside of my thought, nor ever have been, nevertheless the figure cannot help having a certain determinate nature... or essence, which is immutable and eternal, which I have not invented and which does not in any way depend upon my mind. (Descartes, 1951, p. 61)

   2) Examine What Is within Our Reach

   Let us console ourselves for not knowing the possible connections between a spider and the rings of Saturn, and continue to examine what is within our reach. (Voltaire, 1961, p. 144)

   3) Modern Philosophy Starts with the Cartesian Catastrophe

   As modern physics started with the Newtonian revolution, so modern philosophy starts with what one might call the Cartesian Catastrophe. The catastrophe consisted in the splitting up of the world into the realms of matter and mind, and the identification of "mind" with conscious thinking. The result of this identification was the shallow rationalism of l'esprit Cartesien, and an impoverishment of psychology which it took three centuries to remedy even in part. (Koestler, 1964, p. 148)

   4) The Rightful Claims of Philosophy

   It has been made of late a reproach against natural philosophy that it has struck out on a path of its own, and has separated itself more and more widely from the other sciences which are united by common philological and historical studies. The opposition has, in fact, been long apparent, and seems to me to have grown up mainly under the influence of the Hegelian philosophy, or, at any rate, to have been brought out into more distinct relief by that philosophy.... The sole object of Kant's "Critical Philosophy" was to test the sources and the authority of our knowledge, and to fix a definite scope and standard for the researches of philosophy, as compared with other sciences.... [But Hegel's] "Philosophy of Identity" was bolder. It started with the hypothesis that not only spiritual phenomena, but even the actual world-nature, that is, and man-were the result of an act of thought on the part of a creative mind, similar, it was supposed, in kind to the human mind.... The philosophers accused the scientific men of narrowness; the scientific men retorted that the philosophers were crazy. And so it came about that men of science began to lay some stress on the banishment of all philosophic influences from their work; while some of them, including men of the greatest acuteness, went so far as to condemn philosophy altogether, not merely as useless, but as mischievous dreaming. Thus, it must be confessed, not only were the illegitimate pretensions of the Hegelian system to subordinate to itself all other studies rejected, but no regard was paid to the rightful claims of philosophy, that is, the criticism of the sources of cognition, and the definition of the functions of the intellect. (Helmholz, quoted in Dampier, 1966, pp. 291-292)

   5) The Philosophy of Philosophy

   Philosophy remains true to its classical tradition by renouncing it. (Habermas, 1972, p. 317)

   6) Philosophy Is a Field Which Has Certain Central Questions

   I have not attempted... to put forward any grand view of the nature of philosophy; nor do I have any such grand view to put forth if I would. It will be obvious that I do not agree with those who see philosophy as the history of "howlers" and progress in philosophy as the debunking of howlers. It will also be obvious that I do not agree with those who see philosophy as the enterprise of putting forward a priori truths about the world.... I see philosophy as a field which has certain central questions, for example, the relation between thought and reality.... It seems obvious that in dealing with these questions philosophers have formulated rival research programs, that they have put forward general hypotheses, and that philosophers within each major research program have modified their hypotheses by trial and error, even if they sometimes refuse to admit that that is what they are doing. To that extent philosophy is a "science." To argue about whether philosophy is a science in any more serious sense seems to me to be hardly a useful occupation.... It does not seem to me important to decide whether science is philosophy or philosophy is science as long as one has a conception of both that makes both essential to a responsible view of the world and of man's place in it. (Putnam, 1975, p. xvii)

   7) The Central Task of Philosophy

   What can philosophy contribute to solving the problem of the relation [of] mind to body? Twenty years ago, many English-speaking philosophers would have answered: "Nothing beyond an analysis of the various mental concepts." If we seek knowledge of things, they thought, it is to science that we must turn. Philosophy can only cast light upon our concepts of those things.

   This retreat from things to concepts was not undertaken lightly. Ever since the seventeenth century, the great intellectual fact of our culture has been the incredible expansion of knowledge both in the natural and in the rational sciences (mathematics, logic).

   The success of science created a crisis in philosophy. What was there for philosophy to do? Hume had already perceived the problem in some degree, and so surely did Kant, but it was not until the twentieth century, with the Vienna Circle and with Wittgenstein, that the difficulty began to weigh heavily. Wittgenstein took the view that philosophy could do no more than strive to undo the intellectual knots it itself had tied, so achieving intellectual release, and even a certain illumination, but no knowledge. A little later, and more optimistically, Ryle saw a positive, if reduced role, for philosophy in mapping the "logical geography" of our concepts: how they stood to each other and how they were to be analyzed....

   Since that time, however, philosophers in the "analytic" tradition have swung back from Wittgensteinian and even Rylean pessimism to a more traditional conception of the proper role and tasks of philosophy. Many analytic philosophers now would accept the view that the central task of philosophy is to give an account, or at least play a part in giving an account, of the most general nature of things and of man. (Armstrong, 1990, pp. 37-38)

   8) Philosophy's Evolving Engagement with Artificial Intelligence and Cognitive Science

   In the beginning, the nature of philosophy's engagement with artificial intelligence and cognitive science was clear enough. The new sciences of the mind were to provide the long-awaited vindication of the most potent dreams of naturalism and materialism. Mind would at last be located firmly within the natural order. We would see in detail how the most perplexing features of the mental realm could be supported by the operations of solely physical laws upon solely physical stuff. Mental causation (the power of, e.g., a belief to cause an action) would emerge as just another species of physical causation. Reasoning would be understood as a kind of automated theorem proving. And the key to both was to be the depiction of the brain as the implementation of multiple higher level programs whose task was to manipulate and transform symbols or representations: inner items with one foot in the physical (they were realized as brain states) and one in the mental (they were bearers of contents, and their physical gymnastics were cleverly designed to respect semantic relationships such as truth preservation). (A. Clark, 1996, p. 1)

   9) The Enduring Value of Philosophy

   Socrates of Athens famously declared that "the unexamined life is not worth living," and his motto aptly explains the impulse to philosophize. Taking nothing for granted, philosophy probes and questions the fundamental presuppositions of every area of human inquiry.... [P]art of the job of the philosopher is to keep at a certain critical distance from current doctrines, whether in the sciences or the arts, and to examine instead how the various elements in our world-view clash, or fit together. Some philosophers have tried to incorporate the results of these inquiries into a grand synoptic view of the nature of reality and our human relationship to it. Others have mistrusted system-building, and seen their primary role as one of clarifications, or the removal of obstacles along the road to truth. But all have shared the Socratic vision of using the human intellect to challenge comfortable preconceptions, insisting that every aspect of human theory and practice be subjected to continuing critical scrutiny....

   Philosophy is, of course, part of a continuing tradition, and there is much to be gained from seeing how that tradition originated and developed. But the principal object of studying the materials in this book is not to pay homage to past genius, but to enrich one's understanding of central problems that are as pressing today as they have always been-problems about knowledge, truth and reality, the nature of the mind, the basis of right action, and the best way to live. These questions help to mark out the territory of philosophy as an academic discipline, but in a wider sense they define the human predicament itself; they will surely continue to be with us for as long as humanity endures. (Cottingham, 1996, pp. xxi-xxii)

    10) The Distinction between Dionysian Man and Apollonian Man, between Art and Creativity and Reason and Self- Control

   In his study of ancient Greek culture, The Birth of Tragedy, Nietzsche drew what would become a famous distinction, between the Dionysian spirit, the untamed spirit of art and creativity, and the Apollonian, that of reason and self-control. The story of Greek civilization, and all civilizations, Nietzsche implied, was the gradual victory of Apollonian man, with his desire for control over nature and himself, over Dionysian man, who survives only in myth, poetry, music, and drama. Socrates and Plato had attacked the illusions of art as unreal, and had overturned the delicate cultural balance by valuing only man's critical, rational, and controlling consciousness while denigrating his vital life instincts as irrational and base. The result of this division is "Alexandrian man," the civilized and accomplished Greek citizen of the later ancient world, who is "equipped with the greatest forces of knowledge" but in whom the wellsprings of creativity have dried up. (Herman, 1997, pp. 95-96)

   1) The Ego Is Not Even Master in Its Own House

   [Psychoanalysis] seeks to prove to the ego that it is not even master in its own house, but must content itself with scanty information of what is going on unconsciously in the mind. (Freud, 1953-1974, Vol. 16, pp. 284-285)

   2) Methodological Problems of Psychoanalysis

   Although in the interview the analyst is supposedly a "passive" auditor of the "free association" narration by the subject, in point of fact the analyst does direct the course of the narrative. This by itself does not necessarily impair the evidential worth of the outcome, for even in the most meticulously conducted laboratory experiment the experimenter intervenes to obtain the data he is after. There is nevertheless the difficulty that in the nature of the case the full extent of the analyst's intervention is not a matter that is open to public scrutiny, so that by and large one has only his own testimony as to what transpires in the consulting room. It is perhaps unnecessary to say that this is not a question about the personal integrity of psychoanalytic practitioners. The point is the fundamental one that no matter how firmly we may resolve to make explicit our biases, no human being is aware of all of them, and that objectivity in science is achieved through the criticism of publicly accessible material by a community of independent inquirers.... Moreover, unless data are obtained under carefully standardized circumstances, or under different circumstances whose dependence on known variables is nevertheless established, even an extensive collection of data is an unreliable basis for inference. To be sure, analysts apparently do attempt to institute standard conditions for the conduct of interviews. But there is not much information available on the extent to which the standardization is actually enforced, or whether it relates to more than what may be superficial matters. (E. Nagel, 1959, pp. 49-50)

   3) No Necessary Incompatibility between Psychoanalysis and Certain Religious Formulations

   here would seem to be no necessary incompatibility between psychoanalysis and those religious formulations which locate God within the self. One could, indeed, argue that Freud's Id (and even more Groddeck's It), the impersonal force within which is both the core of oneself and yet not oneself, and from which in illness one become[s] alienated, is a secular formation of the insight which makes religious people believe in an immanent God. (Ryecroft, 1966, p. 22)

   4) The Problem of Verifying Psychoanalytic Theory

   Freudian analysts emphasized that their theories were constantly verified by their "clinical observations."... It was precisely this fact-that they always fitted, that they were always confirmed-which in the eyes of their admirers constituted the strongest argument in favour of these theories. It began to dawn on me that this apparent strength was in fact their weakness.... It is easy to obtain confirmations or verifications, for nearly every theory-if we look for confirmation. (Popper, 1968, pp. 3435)

   5) Psychoanalysis Is Not a Science But Rather the Interpretation of a Narrated History

   Psychoanalysis does not satisfy the standards of the sciences of observation, and the "facts" it deals with are not verifiable by multiple, independent observers.... There are no "facts" nor any observation of "facts" in psychoanalysis but rather the interpretation of a narrated history. (Ricoeur, 1974, p. 186)

   6) Some of the Qualities of a Scientific Approach Are Possessed by Psychoanalysis

   In sum: psychoanalysis is not a science, but it shares some of the qualities associated with a scientific approach-the search for truth, understanding, honesty, openness to the import of the observation and evidence, and a skeptical stance toward authority. (Breger, 1981, p. 50)

   7) Major Attributes of Psychoanalysis

   [Attributes of Psychoanalysis:]

   1. Psychic Determinism. No item in mental life and in conduct and behavior is "accidental"; it is the outcome of antecedent conditions.

   2. Much mental activity and behavior is purposive or goal-directed in character.

   3. Much of mental activity and behavior, and its determinants, is unconscious in character. 4. The early experience of the individual, as a child, is very potent, and tends to be pre-potent over later experience. (Farrell, 1981, p. 25)

   8) The Scientific and Rational Are Not Co- extensive

   Our sceptic may be unwise enough... to maintain that, because analytic theory is unscientific on his criterion, it is not worth discussing. This step is unwise, because it presupposes that, if a study is not scientific on his criterion, it is not a rational enterprise... an elementary and egregious mistake. The scientific and the rational are not co-extensive. Scientific work is only one form that rational inquiry can take: there are many others. (Farrell, 1981, p. 46)

   9) The Validity of Psychoanalytic Therapy

   Psychoanalysts have tended to write as though the term analysis spoke for itself, as if the statement "analysis revealed" or "it was analyzed as" preceding a clinical assertion was sufficient to establish the validity of what was being reported. An outsider might easily get the impression from reading the psychoanalytic literature that some standardized, generally accepted procedure existed for both inference and evidence. Instead, exactly the opposite has been true. Clinical material in the hands of one analyst can lead to totally different "findings" in the hands of another. (Peterfreund, 1986, p. 128)

    10) The Issues of Inference and Evidence in Psychoanalysis

   The analytic process-the means by which we arrive at psychoanalytic understanding-has been largely neglected and is poorly understood, and there has been comparatively little interest in the issues of inference and evidence. Indeed, psychoanalysts as a group have not recognized the importance of being bound by scientific constraints. They do not seem to understand that a possibility is only that-a possibility-and that innumerable ways may exist to explain the same data. Psychoanalysts all too often do not seem to distinguish hypotheses from facts, nor do they seem to understand that hypotheses must be tested in some way, that criteria for evidence must exist, and that any given test for any hypothesis must allow for the full range of substantiation/refutation. (Peterfreund, 1986, p. 129)

In simple terms, a padlock has three major components; the Body, the Shackle and the Locking Mechanism, …it may also incorporate features such as a weatherproof casing, anti drill or anti cropping protection, etc.

Discus style padlocks - have no angular corners, so are often used with cycle security chains and cables, as well as being a popular choice for securing doors on sheds and beach huts, etc. When used as a door lock, they will typically be used in conjunction with the special shrouded discus hasp and staple set, which offers extra protection to the padlock shackle.

Shutter Locks / Anvil Locks - are typically used to secure the external (or internal) security roller shutters fitted to shop fronts. They are also popular for use with parking posts, motorcycle security chains, etc.

Conventional Style padlocks have a wide range of applications from low security applications like locking your toolbox, to high security uses such as securing factory gates or protecting motorcycles. They are typically available as; Open, Close, or Semi Enclosed Shackle types

Shackleless type padlock (shown with special hasp)

Shackleless Padlocks - this is a bit of a misnomer as the padlock does of course have a shackle, it’s just that it’s on the underside of the lock body and therefore unseen. This type of padlock can be round (like the one pictured) or rectangular, but typically, they are designed to be used with a special matching security hasp. Because of their design, these units are difficult to attack and over recent years, as well as being used on warehouse doors, etc, they have also become very popular for use on vans and other vehicles where they are used to secure opening double doors.

A "Close Shackle" padlock is one with built in shoulders, which are designed to minimise the amount of the shackle exposed, to a saw or bolt cropper attack. This type of padlock will normally have a higher security rating than an equivalent unit with a semi enclosed or open shackle, however subject to size and clearances, may not be practical for instance, to use where you need to secure 2 chain links together or require a padlock for use with a shrouded hasp, etc. To make them easier to use, many Close Shackle padlocks feature "removable shackles" which are fully released from the body of the padlock when it's unlocked.

 

An "Open Shackle" padlock will typically be easier to use where the shackle needs to pass through 2 chain-links (i.e, a chain securing two opening gates together), etc. As more of the shackle is exposed however, this makes it potentially easier to attack with a saw or bolt croppers.

 

A "Semi Enclosed Shackle" padlock is something of a compromise, but will often offer more flexibility in use than a Close Shackle padlock and improved security over an Open Shackle model.

cockroach
The most primitive of the living winged insects. It is thought they have been unchanged for more than 300 million years, and are among the oldest fossil insects. Cockroaches are usually found in tropical climates, but a few species, out of the total 3.500 known species, have become pests. They are common household pests in many countries, imported by ship and carried home in grocery bags. Cockroaches eat plant and animal products, including food, paper, clothing and soiled hospital waste, fouling everything they touch with their droppings and unpleasant odour, to which many people are allergic. They are a major health hazard and carry harmful bacteria, protozoan parasites and faunal pathogens, including those that cause typhoid, leprosy and salmonella. Conventional insecticides make little or no impact on the cockroaches population. (Source: WRIGHT / WPR)
