The Life of Reason by George Santayana — Read

Dialectic better than physics.

Common knowledge passes from memory to history and from history to mechanism; and having reached that point it may stop to look back, not without misgivings, over the course it has traversed, and thus become psychology. These investigations, taken together, constitute physics, or the science of existence. But this is only half of science and on the whole the less interesting and less fundamental half. No existence is of moment to a man, not even his own, unless it touches his will and fulfils or thwarts his intent. Unless he is concerned that existences should be of specific kinds, unless he is interested in form, he can hardly be interested in being. At the very least in terms of pleasure versus pain, light versus darkness, comfort versus terror, the flying moment must be loaded with obloquy or excellence if its passage is not to remain a dead fact, and to sink from the sphere of actuality altogether into that droning limbo of potentialities which we call matter. Being which is indifferent to form is only the material of being. To exist is nothing if you have nothing to do, if there is nothing to choose or to distinguish, or if those things which belong to a chosen form are not gathered into it before your eyes, to express what we call a truth or an excellence.
