101 Behaviorism
A person is changed by the contingencies of reinforcement under which he behaves; he does not store the contingencies. In particular, he does not store copies of the stimuli which have played a part in the contingencies. There are no "iconic representations" in his mind; there are no "data structures stored in his memory"; he has no "cognitive map" of the world in which he has lived. He has simply been changed in such a way that stimuli now control particular kinds of perceptual behavior. (Skinner, 1974, p. 84)Psychology as the behaviorist views it is a purely objective natural science. Its theoretical goal is the prediction and control of behavior. Introspection forms no essential part of its method nor is the scientific value of its data dependent upon the readiness with which they lend themselves to interpretation in terms of consciousness. The behaviorist, in his efforts to get a unitary scheme of animal response, recognizes no dividing line between man and brute. The behavior of man, with all its refinement and complexity, forms only a part of the behaviorist's total scheme of investigation.

102 Experience
Any kind of experience-accidental impressions, observations, and even "inner experience" not induced by stimuli received from the environment-may initiate cognitive processes leading to changes in a person's knowledge. Thus, new knowledge can be acquired without new information being received. (That this statement refers to subjective knowledge goes without saying; but there is no such thing as objective knowledge that was not previously somebody's subjective knowledge. (Machlup & Mansfield, 1983, p. 644)Our faith in experience is far from well grounded, because we have an untenable concept of the nature of experience, one that assumes truth is manifest, and does not have to be inferred. (Brehmer, 1986, p. 715)I now wish to unfold the principles of experimental science, since without experience nothing can be sufficiently known. For there are two modes of acquiring knowledge, namely by reasoning and experience. Reasoning draws a conclusion and makes us grant the conclusion, but does not make the conclusion certain, nor does it remove doubt so that the mind may rest on the intuition of truth, unless the mind discovers it by the path of experience.... Aristotle's statement then that proof is reasoning that causes us to know is to be understood with the proviso that the proof is accompanied by its appropriate experience, and is not to be understood of the bare proof.... He therefore who wishes to rejoice without doubt in regard to the truths underlying phenomena must know how to devote himself to experiment. (Bacon, 1928, Pt. VI, Chap. 1)Historical dictionary of quotations in cognitive science > Experience
