If we remembered everything, we should on most occasions be as ill off — William James

"The union of the mathematician with the poet, fervor with measure, passion with correctness, this surely is the ideal."

"I think that yesterday was a crisis in my life. I finished the first part of Renouviers second Essais and see no reason why his definition of free will—"the sustaining of a thought because I choose to when I might have other thoughts"—need be the definition of an illusion. At any rate, I will assume for the present—until next year—that it is no illusion. My first act of free will shall be to believe in free will."

"Habit is thus the enormous fly-wheel of society, its most precious conservative agent. It alone is what keeps us all within the bounds of ordinance, and saves the children of fortune from the envious uprisings of the poor."

"As we take, in fact, a general view of the wonderful stream of our consciousness, what strikes us first is this different pace of its parts. Like a birds life, it seems to be made of an alternation of flights and perchings."

"The last peculiarity of consciousness to which attention is to be drawn in this first rough description of its stream is that it is always interested more in one part of its object than in another, and welcomes and rejects, or chooses, all the while it thinks."

"Alexanders career was piracy pure and simple, nothing but an orgy of power and plunder, made romantic by the character of the hero. There was no rational purpose in it, and the moment he died his generals and governors attacked one another."

"In the life of the mass-order, the culture of the generality tends to conform to the demands of the average human being. Spirituality decays through being diffused among the masses when knowledge is impoverished in every possible way by rationalisation until it becomes accessible to the crude understanding of all."

"I say this to you because we Spaniards are a forgetful people, because we are used to living for the moment, because we do not look back, because we do not know how to see the chain of heroes, because we do not contemplate the sum of sacrifices."

"Sharon Tate was my best friend. Once, we were roommates. She introduced me to my husband. She was the godmother to my baby daughter who is named for her. In the six years time that I knew her, she never said an unkind word about anyone."

"Long time to see. (VS: Tapion)"

"Most mathematicians prove what they can, von Neumann proves what he wants." Once in a discussion about the rapid growth of mathematics in modern times, von Neumann was heard to remark that whereas thirty years ago a mathematician could grasp all of mathematics, that is impossible today. Someone asked him: "What percentage of all mathematics might a person aspire to understand today?" Von Neumann went into one of his five-second thinking trances, and said: "About 28 percent."

"Children must be free to think in all directions irrespective of the peculiar ideas of parents who often seal their childrens minds with preconceived prejudices and false concepts of past generations. Unless we are very careful, very careful indeed, and very conscientious, there is still great danger that our children may turn out to be the same kind of people we are."
