NON-ARISTOTELIAN FACTORS
The men most disdainful of theory get from it, without suspecting it, their daily bread; deprived of this food, progress would quickly cease, and we should soon congeal into the immobility of old China. (417) h. poincare
If one wishes to obtain a definite answer from Nature one must attack the question from a more general and less selfish point of view. (415)
M. PLANCK
In particular - if we use the word intelligence as a synonym for mental activity, as is often done - we must differentiate between the primitive forms of sensory intelligence, with their ill-developed symbolism beyond which backward children cannot advance, . . . and the forms of verbal intelligence created by social education, abstract and conceptual forms. (411)
HENRI PIERON
A civilisation which cannot burst through its current abstractions is doomed to sterility after a very limited period of progress. (575)
A. N. WHITEHEAD
. . . almost any idea which jogs you out of your current abstractions may be better than nothing. (575)                                          a. n. whitehead
That is precisely what common sense is for, to be jarred into uncommon sense. One of the chief services which mathematics has rendered the human race in the past century is to put 'common sense' where it belongs, on the topmost shelf next to the dusty canister labeled 'discarded nonsense.' (23)
E. T. BELL
If you have had your attention directed to the novelties in thought in your own lifetime, you will have observed that almost all really new ideas have a certain aspect of foolishness when they are first produced. (575)
A. N. WHITEHEAD
To know how to criticize is good, to know how to create is better. (417)
H. POINCARE
The explanatory crisis which now confronts us in relativity and quantum phenomena is but a repetition of what has occurred many times in the past. ... Every kitten is confronted with such a crisis at the end of nine days. (55)
P. W. BRIDGMAN
The concept does not exist for the physicist until he has the possibility of discovering whether or not it is fulfilled in an actual case. ... As long as this requirement is not satisfied, I allow myself to be deceived as a physicist (and of course the same applies if I am not a physicist), when I imagine that I am able to attach a meaning to the statement of simultaneity. (I would ask the reader not to proceed farther until he is fully convinced on this point.) (150)                                                                               A. EINSTEIN
Einstein, in thus analyzing what is involved in making a judgment of simultaneity, and in seizing on the act of the observer as the essence of the situation, is actually adopting a new point of view as to what the concepts of physics should be, namely, the operational view ... if we had adopted the operational point of view, we would, before the discovery of the actual physical facts, have seen that simultaneity is essentially a relative concept, and would have left room in our thinking for the discovery of such effects as were later found.
