If you want to find out anything from the theoretical physicists about the methods they use, I advise you to stick closely to one principle: don't listen to their words, fix your attention on their deeds. To him who is a discoverer in this field the products of his imagination appear so necessary and natural that he regards them, and would like to have them regarded by others, not as creations of thought but as given realities.
Know that all sins and all evils can be summed up in that one word, weakness. It is weakness that is the motive power in all evil doing; it is weakness that makes men injure others; it is weakness that makes them manifest what they are not in reality. Let them know what they really are.
And, moreover, when it happens that both are sincere and good, nothing will mix and amalgamate more easily than an old priest and an old soldier. In reality, they are the same kind of man. One has devoted himself to country upon earth, the other to his country in heaven; there is no other difference.
Our life is two fold Sleep hath its own world, A boundary between the things misnamed Death and existence Sleep hath its own world, And a wide realm of wild reality.
The soul consists of two parts, one irrational and the other capable of reason. (Whether these two parts are really distinct in the sense that the parts of the body or of any other divisible whole are distinct, or whether though distinguishable in thought as two they are inseparable in reality, like the convex and concave of a curve, is a question of no importance for the matter in hand.)
Between the idea And the reality Between the motion And the act Falls the Shadow For Thine is the Kingdom Between the conception And the creation Between the emotion And the response Falls the Shadow Life is very long Between the desire And the spasm Between the potency And the existence Between the essence And the descent Falls the Shadow For Thine is the Kingdom For Thine is Life is For Thine is the This is the way the world ends This is the way the world ends This is the way the world ends Not with a bang but a whimper.
We coin concepts and we use them to analyse and explain nature and society. But we seem to forget, midway, that these concepts are our own constructs and start equating them with reality.
