God is the Immanent Cause of all things, never truly transcendent from them.

The science of pure mathematics, in its modern developments, may claim to be the most original creation of the human spirit.

I do not pretend to start with precise questions. I do not think you can start with anything precise. You have to achieve such precision as you can, as you go along.

The vocation of every man and woman is to serve other people.

I hold in fact(1) That small portions of space are in fact of a nature analogous to little hills on a surface which is on the average flat; namely, that the ordinary laws of geometry are not valid in them.(2) That this property of being curved or distorted is continually being passed on from one portion of space to another after the manner of a wave.(3) That this variation of the curvature of space is what really happens in that phenomenon which we call the motion of matter, whether ponderable or etherial.(4) That in the physical world nothing else takes place but this variation, subject possibly to the law of continuity.

When we assume God to be a guiding principle-well, sure enough, a god is usually characteristic of a certain system of thought or morality. For instance, take the Christian God, the summum bonum: God is love, love being the highest moral principle; and God is spirit, the spirit being the supreme idea of meaning. All our Christian moral concepts derive from such assumptions, and the supreme essence of all of them is what we call God.

Science can only be comprehended epistemologically, which means as one category of possible knowledge, as long as knowledge is not equated either effusively with the absolute knowledge of a great philosophy or blindly with scientistic self-understanding of the actual business of research.

The class of big capitalists, who, in all civilized countries, are already in almost exclusive possession of all the means of subsistance and of the instruments (machines, factories) and materials necessary for the production of the means of subsistence. This is the bourgeois class, or the bourgeoisie.

The existence of the mind-independent environment beyond one's world-simulation is a theoretical inference, not an empirical observation.

Living a minimally acceptable ethical life involves using a substantial part of our spare resources to make the world a better place. Living a fully ethical life involves doing the most good we can.

The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

Not far from the invention of fire... we must rank the invention of doubt.

The student of mathematics often finds it hard to throw off the uncomfortable feeling that his science, in the person of his pencil, surpasses him in intelligence,-an impression which the great Euler confessed he often could not get rid of. This feeling finds a sort of justification when we reflect that the majority of the ideas we deal with were conceived by others, often centuries ago. In a great measure it is really the intelligence of other people that confronts us in science.

Practice humility at first with man and only then before God. He who despises man, has also no respect for God.

... the only contestant who can confidently enter the lists is the man who has seen his own blood, who has felt his teeth rattle beneath his opponent's fist, who has been tripped and felt the full force of his adversary's charge, who has been downed in body but not in spirit, one who, as often as he falls, rises again with greater defiance than ever.

We are not ostriches, and cannot believe that if we refuse to look at what we do not wish to see, it will not exist. This is especially the case when what we do not wish to see is what we wish to eat. If it were really indispensable, or, if not indispensable, at least in some way useful! But it is quite unnecessary ... And this is continually being confirmed by the fact that young, kind, undepraved people - especially women and girls - without knowing how it logically follows, feel that virtue is incompatible with beefsteaks, and, as soon as they wish to be good, give up eating flesh.

When a reasonable Soul forsaketh his divine nature, and becometh beast-like, it dieth. For though the substance of the Soul be incorruptible: yet, lacking the use of Reason, it is reputed dead; for it loseth the Intellective Life.

Poetry can be written only because it has been written.

The members of Christ, many though they be, are bound to one another by the ties of charity and peace under the one Head, who is our Saviour Himself, and form one man. Often their voice is heard in the Psalms as the voice of one man; the cry of one is as the cry of all, for all are one in One.

Gratitude is a burden, and every burden is made to be shaken off.

The more remote and unreal the personal mother is, the more deeply will the son's yearning for her clutch at his soul, awakening that primordial and eternal image of the mother for whose sake everything that embraces, protects, nourishes, and helps assumes maternal form, from the Alma Mater of the university to the personification of cities, countries, sciences and ideals.

Let a man take time enough for the most trivial deed, though it be but the paring of his nails. The buds swell imperceptibly, without hurry or confusion; as if the short spring days were an eternity.

For a consistent naturalist science can only be a refinement of animal exploration, a practice humans have devised for finding their way in the bit of the universe in which they have so far survived. Instead of thinking of science as a law-seeking activity, we can think of it as a tool humans use to cope with a world they will never understand.

Antisthenes ... said once to a youth from Pontus who was on the point of coming to him to be his pupil, and was asking him what things he wanted, "You want a new book, and a new pen, and a new tablet;"

In the end, I am moved by causes and ideas that I can actually choose to support because they conform to values and principles that I believe in.

It would be too ridiculous to go about seriously to prove that wealth does not consist in money, or in gold and silver; but in what money purchases, and is valuable only for purchasing. Money no doubt, makes always a part of the national capital; but it has already been shown that it generally makes but a small part, and always the most unprofitable part of it.

It was the addition of status that brought the little things: a more comfortable seat here, a better cut of meat there, a shorter wait in line at the other place. To the philosophical mind, these items might seem scarcely worth any great trouble to acquire.Yet no one, however philosophical, could give up those privileges, once acquired, without a pang. That was the point.

The worst of misfortunes is still a stroke of luck, since one feels oneself living when one experiences it.

If you look at the sociology of populism in the United States, it is tied most closely to population density, which... is correlated... to these types of cultural differences... to belief... in traditional cultural values, in family, in religion and the like, and conversely to... belief in immigration and diversity as strengths... This is the fundamental division that's taken hold of the United States. It has been augmented by technology because the internet has succeeded in... destroying every other source of authority that used to filter news and facts and information that... formed the basis of a democratic ability to have political discourse.

Hatred comes from the heart; contempt from the head; and neither feeling is quite within our control.

What could be a better indication of man's continued dependence on nature than the fact that today's so-called post-industrial societies satisfy most of their food needs through imports from so-called underdeveloped countries?

It is the natural effect of improvement, however, to diminish gradually the real price of almost all manufactures.

With his sharp power of vision, resolute power of action, I doubt not he could have learned to write Books withal, and speak fluently enough;-he did harder things than writing of Books. This kind of man is precisely he who is fit for doing manfully all things you will set him on doing.

A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.

Every man bears the whole stamp of the human condition.

The infant runs toward it with its eyes closed, the adult is stationary, the old man approaches it with his back turned.

The earth belongs to the living, not to the dead.

There were never in the world two opinions alike, any more than two hairs or two grains. Their most universal quality is diversity.

At dawn, when you have trouble getting out of bed, tell yourself: 'I have to go to work - as a human being. What do I have to complain of, if I'm going to do what I was born for - the things I was brought into the world to do? Or is this what I was created for? To huddle under the blankets and stay warm?' 

The general fellowship of our human situation has been rendered even more dubious than before, inasmuch as, though the old ties of caste have been loosened, a new restriction of the individual to some prescribed status in society is manifest. Less than ever, perhaps, is it possible for a man to transcend the limitations imposed by his social origins.

May some future student go over this ground again, and have the leisure to give his results to the world.

I get along quite well with someone only when he is at his lowest point and has neither the desire nor the strength to restore his habitual illusions.

Nothing in all literature is so depressing as the "Dissertations" of the slave [Epictetus], unless it be the "Meditations" of the Emperor [Marcus Aurelius] ...[after some excerpts from the two books]..... In such passages we feel the proximity of Christianity and its dauntless martyrs; indeed were not the Christian ethic of self-denial, the Christian political ideal of an almost communistic brotherhood of man, and the Christian eschatology of the final conflagration of all the world, fragments of Stoic doctrine floating on the stream of thought? In Epictetus the Greco-Roman soul has lost its paganism, and is ready for a new faith".

The antagonism between science and religion, about which we hear so much, appears to me to be purely factitious - fabricated, on the one hand, by short-sighted religious people who confound a certain branch of science, theology, with religion; and, on the other, by equally short-sighted scientific people who forget that science takes for its province only that which is susceptible of clear intellectual comprehension; and that, outside the boundaries of that province, they must be content with imagination, with hope, and with ignorance.

In the effort to tell a whole story, to see it whole and clear, I have had to imagine more than I have known.

Anarchism is the only philosophy which brings to man the consciousness of himself; which maintains that God, the State, and society are non-existent, that their promises are null and void, since they can be fulfilled only through man's subordination.

A scholar who loves comfort is not worthy of the name.

All words at every level of prose and poetry and all devices of language and speech derive their meaning from figure / ground relation.
