The cookbook gives a detailed description of ingredients and procedures but no proofs for its prescriptions or reasons for its recipes; the proof of the pudding is in the eating. ... Mathematics cannot be tested in exactly the same manner as a pudding; if all sorts of reasoning are debarred, a course of calculus may easily become an incoherent inventory of indigestible information.

America is woven of many strands; I would recognize them and let it so remain. It's "winner take nothing" that is the great truth of our country or of any country. Life is to be lived, not controlled; and humanity is won by continuing to play in face of certain defeat. Our fate is to become one, and yet many- This is not prophecy, but description.
Ralph Ellison
Education is a companion which no misfortune can depress, no crime can destroy, no enemy can alienate, no despotism can enslave. At home, a friend, abroad, an introduction, in solitude a solace and in society an ornament. It chastens vice, it guides virtue, it gives at once grace and government to genius. Without it, what is man A splendid slave, a reasoning savage.
Joseph Addison
Their [those with eating disorders'] task is to rescue themselves from a drive that is destroying them. Food embodies the false values that their own bodies refuse to assimilate, by which I mean that their bodies become edemic, bloated, allergic, or resort to vomiting the poison out. The unconscious body, and certainly the conscious body, will not tolerate the negative mother.
Marion Woodman
It is what makes conscious of the conditions and laws of observing which applied in this manner become a theme on its own. The activity of consciousness depending on the way the work itself proceeds, becomes the subject of my attention this way and it is precisely because of this voyeuristic attitude toward the own observation and experience of the subject that the conscious analytic dimension in the work shows.
Antoni Tàpies
A writer's life is a highly vulnerable, almost naked activity. We don't have to weep about that. The writer makes his choice and is stuck with it. But it is true to say that you are open to all the winds, some of them icy indeed. You are out on your own, out on a limb. You find no shelter, no protection - unless you lie - in which case of course you have constructed your own protection and, it could be argued, become a politician.
Harold Pinter
