The future, like everything else, is no longer quite what it used to be.

History is the science of things which are not repeated.

That which has been believed by everyone, always and everywhere, has every chance of being false.

My hand feels touched as well as it touches; reality says this, and nothing more.

Science is feasible when the variables are few and can be enumerated; when their combinations are distinct and clear. We are tending toward the condition of science and aspiring to do it. The artist works out his own formulas; the interest of science lies in the art of making science.

If what has happened in the one person were communicated directly to the other, all art would collapse, all the effects of art would disappear.

Every man expects some miracle — either from his mind or from his body or from someone else or from events.
