"The union of the mathematician with the poet, fervor with measure, passion with correctness, this surely is the ideal."
"The ideal power with which we feel ourselves in connection, the God of ordinary men, is, both by ordinary men and by philosophers, endowed with certain of those metaphysical attributes which in the lecture on philosophy I treated with such disrespect. He is assumed as a matter of course to be one and only, and to be infinite; and the notion of many finite gods is one which hardly any one thinks it worth while to consider, and still less to uphold. Nevertheless, in the interests of intellectual clearness, I feel bound to say that religious experience, as we have studied it, cannot be cited as unequivocally supporting the infinitist belief. The only thing that it unequivocally testifies to is that we can experience union with something larger than ourselves and in that union find our greatest peace. Philosophy, with its passion for unity, and mysticism with its monoideistic bent, both pass to the limit and identify the something with a unique God who is the all-inclusive soul of the world. Popular opinion, respectful to their authority, follows the example which they set."

William James was an American philosopher and psychologist. The first educator to offer a psychology course in the United States, he is considered to be one of the leading thinkers of the late 19th century, one of the most influential philosophers and is often dubbed the "father of American psychology".

"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 did not go to join Kurtz there and then. I did not. I remained to dream the nightmare out to the end, and to show my loyalty to Kurtz once more. Destiny. My destiny! Droll thing life is — that mysterious arrangement of merciless logic for a futile purpose. The most you can hope from it is some knowledge of yourself — that comes too late — a crop of unextinguishable regrets. I have wrestled with death. It is the most unexciting contest you can imagine. It takes place in an impalpable grayness, with nothing underfoot, with nothing around, without spectators, without clamor, without glory, without the great desire of victory, without the great fear of defeat, in a sickly atmosphere of tepid skepticism, without much belief in your own right, and still less in that of your adversary. If such is the form of ultimate wisdom, then life is a greater riddle than some of us think it to be. I was within a hairs-breadth of the last opportunity for pronouncement, and I found with humiliation that probably I would have nothing to say. This is the reason why I affirm that Kurtz was a remarkable man. He had something to say. He said it. Since I had peeped over the edge myself, I understand better the meaning of his stare, that could not see the flame of the candle, but was wide enough to embrace the whole universe, piercing enough to penetrate all the hearts that beat in the darkness. He had summed up — he had judged. The horror! He was a remarkable man. After all, this was the expression of some sort of belief; it had candor, it had conviction, it had a vibrating note of revolt in its whisper, it had the appalling face of a glimpsed truth — the strange commingling of desire and hate."
"Ive been taking a closer look at these graduates. They are actually taller, stronger, smarter than we were, smart enough maybe to take our mistakes as their messages, to make our weaknesses their lessons, and to make our example — good and not so good — part of their education."
"All men suppose what is called Wisdom to deal with the first causes and the principles of things; so that, as has been said before, the man of experience is thought to be wiser than the possessors of any sense-perception whatever, the artist wiser than the men of experience, the masterworker than the mechanic, and the theoretical kinds of knowledge to be more of the nature of Wisdom than the productive."
"My specific... object has been to contain, within the prescribed limits, the whole of the students course, from the confines of elementary algebra and trigonometry, to the entrance of the highest works on mathematical physics. A learner who has a good knowledge of the subjects just named, and who can master the present treatise, taking up elementary works on conic sections, application of algebra to geometry, and the theory of equations, as he wants them, will, I am perfectly sure, find himself able to conquer the difficulties of anything he may meet with; and need not close any book of Laplace, Lagrange, Legendre, Poisson, Fourier, Cauchy, Gauss, Abel, Hindenburgh and his followers. or of any one of our English mathematicians, under the idea that it is too hard for him."
"Religious faith in the case of the Hindus has never been allowed to run counter to scientific laws, moreover the former is never made a condition for the knowledge they teach, but there are always scrupulously careful to take into consideration the possibility that by reason both the agnostic and atheist may attain truth in their own way. Such tolerance may be surprising to religious believers in the West, but it is an integral part of Vedantic belief."
