CHAPTER XVII
ON THE NOTIONS OF 'MATTER', 'SPACE', 'TIME*
Common sense starts with the notion that there is matter where we can get sensations of touch, but not elsewhere. Then it gets puzzled by wind, breath, clouds, etc., whence it is led to the conception of "spirit" - I speak etymologically. After "spirit" has been replaced by "gas," there is a further stage, that of the aether. (457)                                bkrtrand russell
The supposition of common sense and naive realism, that we see the actual physical object, is very hard to reconcile with the scientific view that our perception occurs somewhat later than the emission of light by the object; and this difficulty is not overcome by the fact that the time involved, like the notorious baby, is a very little one. (457)
BERTRAND RUSSELL
We have certain preconceived ideas about location in space which have come down to us from ape-like ancestors. (149)                       a. s. eddington
But it does not seem a profitable procedure to make odd noises on the off-chance that posterity will find a significance to attribute to them.
(149)                                                                                              A. S. EDDINGTON
There is a blessed phrase "hidden reserves"; and generally speaking the more respectable the company the more widely does its balance-sheet deviate from reality. This is called sound finance. . . . Thanks to Minkowski a way of keeping accounts has been found which exhibits realities (absolute things) and balances. (149)            a. s. eddington
The quest of the absolute leads into the four-dimensional world. (149)
A. s. eddington
The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality. (352)                                         h. Minkowski
It is a thing; not like space, which is a mere negation; nor like time, which is - Heaven knows what! (149)                                       a. s. eddington
Newton objectivises space. Since he classes his absolute space together with real things, for him rotation relative to an absolute space is also something real. (isi>                                                                                  a. einstein
Space is only a word that we have believed a thing. (417) h. poincare
In fact, our ordinary description of nature, and the idea of exact laws, rests on the assumption that it is possible to observe the phenomena without appreciably influencing them. (215)                                     w. heisenberg
Even when this arbitrariness is taken into account the concept "observation" belongs, strictly speaking, to the class of ideas borrowed from the experiences of everyday life. It can only be carried over to atomic phenomena when due regard is paid to the limitations placed on all space-time descriptions by the uncertainty principle. (2is>                        w. heisenberg
