A good hypothesis in science must have other properties than those of the phenomenon it is immediately invoked to explain, otherwise it is not prolific enough.

Or if the hypothesis were offered us of a world in which Messrs. Fourier's and Bellamy's and Morris's Utopias should all be outdone, and millions kept permanently happy on the one simple condition that a certain lost soul on the far-off edge of things should lead a life of lonely torment, what except a specifical and independent sort of emotion can it be which would make us immediately feel, even though an impulse arose within us to clutch at the happiness so offered, how hideous a thing would be its enjoyment when deliberately accepted as the fruit of such a bargain?

Science must constantly be reminded that her purposes are not the only purposes and that the order of uniform causation which she has use for, and is therefore right in postulating, may be enveloped in a wider order, on which she has no claim at all.

Every man who possibly can should force himself to a holiday of a full month in a year, whether he feels like taking it or not.

There is a voice inside which speaks and says, "This is the real me!"

[T]here is very little difference between one person and another, but what little difference ther eis, is very important.

Anything you may hold firmly in your imagination can be yours.
