I cannot praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary, but slinks out of the race where that immortal garland is to be run for, not without dust and heat. Assuredly we bring not innocence into the world, we bring impurity much rather; that which purifies us is trial, and trial is by what is contrary.
Freud pointed out, in his Problem of Lay Analysis , that it is extremely unlikely that a young man who would throw the best years of his life into the cloistered drudgery of getting an M.D. degree, could possibly make a good psychoanalyst; so he preferred to look for young analysts among the writers, the lawyers, the mothers of families, those who had chosen human contact. But in their economic wisdom, the Psychoanalytic Institute of Vienna (and New York) overruled him.paul goodman
If one cannot state a matter clearly enough so that even an intelligent twelve-year-old can understand it, one should remain within the cloistered walls of the university and laboratory until one gets a better grasp of one's subject matter.Margaret Mead
We are not put into this world to sit still and know; we are put into it to act. It is true that in order to learn men must for a little while withdraw from action, must seek some quiet place of remove from the bustle of affairs, where their thoughts may run clear and tranquil, and the heats of business be for the time put off; but that cloistered refuge is no place to dream in.
