H. A. Lorentz has found out the Relativity theorem and has created the Relativity postulate as a hypothesis that electrons and matter suffer contractions in consequence of their motion according to a certain law. A. Einstein has brought out the point very clearly, that this postulate is not an artificial hypothesis but is rather a new way of comprehending the time-concept, which is forced upon us by observation of natural phenomena.

I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.
G. H. Hardy
In the Gospels, for instance, we sometimes find the kingdom of heaven illustrated by principles drawn from observation of this world rather than from an ideal conception of justice; ... They remind us that the God we are seeking is present and active, that he is the living God; they are doubtless necessary if we are to keep religion from passing into a mere idealism and God into the vanishing point of our thought and endeavour.
George Santayana
Mine is a very matter-of-fact approach to the problem. If you can select a population and they're educated and they're properly brought up, then you don't have to use too much of the stick because they would already have been trained. It's like with dogs. You train it in a proper way from small. It will know that it's got to leave, go outside to pee and to defecate. No, we are not that kind of society. We had to train adult dogs who even today deliberately urinate in the lifts.

By consequence I hold that no one ever did, or can do, anything for "society."... Comte invented the term altruism as an antonym for egoism, and it found its way at once into everyone's mouth, although it is utterly devoid of meaning, since it points to nothing that ever existed in mankind; This hybrid or rather this degenerate form of hedonism served powerfully to invest collectivism's principles with a specious moral sanction, and collectivists naturally made the most of it.
Albert Jay Nock
At any one time there is a natural tendency among physicists to believe that we already know the essential ingredients of a comprehensive theory. But each time a new frontier of observation is broached we inevitably discover new phenomena which force us to modify substantially our previous conceptions. I believe this process to be unending, that the delights and challenges of unexpected discovery will continue always.
