Totalitarianism in power invariably replaces all first-rate talents, regardless of their sympathies, with those crackpots and fools whose lack of intelligence and creativity is still the best guarantee of their loyalty.

Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty. One person may even perceive deformity, where another is sensible of beauty; and every individual ought to acquiesce in his own sentiment, without pretending to regulate those of others.

Do the essences of proposition and of the truth determine themselves from out of the essence of the thing, or does the essence of the thing determine itself from out of the essence of the proposition? The question is posed as an either/or. However does this either/or itself suffice? Are the essence of the thing and the essence of the proposition only built as mirror images because both of them together determine themselves from out of the same but deeper lying root? However, what and where can be this common ground for the essence of the thing and of the proposition and of their origin? The unconditioned (Unbedingt)? We stated at the beginning that what conditions the essense of the thing in its thingness can no longer itself be thing and conditioned, it must be an unconditioned (Un-bedingtes).

I maintain that in every special natural doctrine only so much science proper is to be met with as mathematics; for... science proper, especially of nature, requires a pure portion, lying at the foundation of the empirical, and based upon à priori knowledge of natural things. ...the conception should be constructed. But the cognition of the reason through construction of conceptions is mathematical. A pure philosophy of nature in general, namely, one that only investigates what constitutes a nature in general, may thus be possible without mathematics; but a pure doctrine of nature respecting determinate natural things (corporeal doctrine and mental doctrine), is only possible by means of mathematics; and as in every natural doctrine only so much science proper is to be met with therein as there is cognition à priori, a doctrine of nature can only contain so much science proper as there is in it of applied mathematics.

The vessel, though her masts be firm, beneath her copper bears a worm.

And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence. 1:4-5 (KJV)

It is one of the chief skills of the philosopher not to occupy himself with questions which do not concern him.

The obliteration of the evil hath been practised by two means, some kind of redemption or expiation of that which is past, and an inception or account de novo for the time to come. But this part seemeth sacred and religious, and justly; for all good moral philosophy (as was said) is but a handmaid to religion.

Are not five sparrows sold for two farthings, and not one of them is forgotten before God? But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows. 12:6-7

It is difficult, if not impossible, to define the limit of our reasonable desires in respect of possessions.

Speed, it seems to me, provides the one genuinely modern pleasure.

Law could never, by determining exactly what is noblest and must just for one and all, enjoin upon them that which is best; for the differences of men and of actions and the fact that nothing, I may say, in human life is ever at rest, forbid any science whatsoever to promulgate any simple rule for everything and for all time. So, that which is persistently simple is inapplicable to things which are never simple.

You called and cried out loud and shattered my deafness. You were radiant and resplendent, you put to flight my blindness. You were fragrant, and I drew in my breath and now pant after you. I tasted you, and I feel but hunger and thirst for you. You touched me, and I am set on fire to attain the peace which is yours.

In obedience to the feeling of reality, we shall insist that, in the analysis of propositions, nothing "unreal" is to be admitted. But, after all, if there is nothing unreal, how, it may be asked, could we admit anything unreal? The reply is that, in dealing with propositions, we are dealing in the first instance with symbols, and if we attribute significance to groups of symbols which have no significance, we shall fall into the error of admitting unrealities, in the only sense in which this is possible, namely, as objects described.

If, when a man writes a poem or commits a murder, the bodily movements involved in his act result solely from physical causes, it would seem absurd to put up a statue to him in the one case and to hang him in the other.

The sun, which passeth through pollutions and itself remains as pure as before.

For many years I was self-appointed inspector of snowstorms and rainstorms, and did my duty faithfully, though I never received one cent for it.

An intolerant sect has no right to complain when it is denied an equal liberty. ... A person's right to complain is limited to principles he acknowledges himself.

Whoever has overthrown an existing law of custom has hitherto always first been accounted a bad man: but when, as did happen, the law could not afterwards be reinstated and this fact was accepted, the predicate gradually changed: - history treats almost exclusively of these bad men who subsequently became good men!

The fault of the utilitarian doctrine is that it mistakes impersonality for impartiality.

An act has no ethical quality whatever unless it be chosen out of several all equally possible.

It is very likely that there are many, many planets carrying life, even intelligent life, throughout the universe, because there are so many stars. By sheer chance, even if those chances are small, a great many life forms and a great many intelligences may exist.

This miracle of analysis, this marvel of the world of ideas, an almost amphibian object between Being and Non-being that we call the imaginary number.

Life continues, and some mornings, weary of the noise, discouraged by the prospect of the interminable work to keep after, sickened also by the madness of the world that leaps at you from the newspaper, finally convinced that I will not be equal to it and that I will disappoint everyone, all I want to do is sit down and wait for evening. This is what I feel like, and sometimes I yield to it.

In this life it is necessary that we be on our guard. To begin with we must be constantly aware of the fact that life here below is best described as being a type of continual warfare. This is a fact that Job, that undefeated soldier of vast experience, tells us so plainly. Yet in this matter the great majority of mankind is often deceived, for the world, like some deceitful magician, captivates their minds with seductive blandishments, and as a result most individuals behave as if there had been a cessation of hostilities.

How could one speak properly about love if you were forgotten, you God of love, source of all love in heaven and on earth; you who spared nothing but in love gave everything; you who are love, so that one who loves is what he is only by being in you.

All the cruelty and torment of which the world is full is in fact merely the necessary result of the totality of the forms under which the will to live is objectified.

Life has no meaning a priori ... It is up to you to give it a meaning, and value is nothing but the meaning that you choose.

Life's short span forbids us to enter on far reaching hopes.

He who is punished is never he who performed the deed. He is always the scapegoat.

The principles of pleasure are not firm and stable. They are different in all mankind, and variable in every particular with such a diversity that there is no man more different from another than from himself at different times.

I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death. Write the things which thou hast seen, and the things which are, and the things which shall be hereafter Revelation 1:18-19

How much good it would do if one could exterminate the human race.

The heavens are as deep as our aspirations are high.

I believe in Christianity as I believe that the sun has risen. Not only because I see it, but because by it I see everything else.

To live, by definition, is not something one learns. Not from oneself, it is not learned from life, taught by life. Only from the other and by death. In any case from the other at the edge of life. At the internal border or the external border, it is a heterodidactics between life and death.

Though the Earth, and all inferior Creatures be common to all Men, yet every Man has a Property in his own Person. Thus no Body has any Right to but himself.

The reservedness and distance that fathers keep, often deprive their sons of that refuge which would be of more advantage to them than an hundred rebukes or chidings.

The study of politics is a form of natural history. Thomas Hobbes loathed Aristotle's politics, and in Leviathan followed Plato in modeling politics on geometry; but he admired Aristotle's biology. One consequence of that "biological" style is important, not only because it was at odds with Hobbes's-and Plato's-hankering after political geometry. Aristotle claimed that political analysis should aim only "at as much precision as the subject matter permits." Political wisdom cannot aspire to the precision of geometry, and must not pretend to. Aboriculture suggests an analogy: most trees grow best in firm soil with a moderate water supply; a few thrive with their roots in mud and water. Alan Ryan, On Politics: A History of Political Thought: From Herodotus to the Present (2012), Ch. 3 : Aristotle: Politics Is Not Philosophy

If a workman can conveniently spare those three halfpence, he buys a pot of porter. If he cannot, he contents himself with a pint, and, as a penny saved is a penny got, he thus gains a farthing by his temperance.

If I made laws for Shakers or a school, I should gazette every Saturday all the words they were wont to use in reporting religious experience, as "spiritual life," "God," "soul," "cross," etc., and if they could not find new ones next week, they might remain silent.

The need of reason is not inspired by the quest for truth but by the quest for meaning. And truth and meaning are not the same. The basic fallacy, taking precedence over all specific metaphysical fallacies, is to interpret meaning on the model of truth.

Beauty is the mark God sets upon virtue.

M. Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind, and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry.

No rules, however wise, are a substitute for affection and tact.

Wherever you are it is your own friends who make your world.

"Everything is already there in...." How does it come about that [an] arrow points? Doesn't it seem to carry in it something besides itself? - "No, not the dead line on paper; only the psychical thing, the meaning, can do that." - That is both true and false. The arrow points only in the application that a living being makes of it.

Their worship was not paid to the demon which such a being as they imagined would really be, but to their own idea of excellence. The evil is, that such a belief keeps the ideal wretchedly low; and opposes the most obstinate resistance to all thought which has a tendency to raise it higher. Believers shrink from every train of ideas which would lead the mind to a clear conception and an elevated standard of excellence, because they feel (even when they do not distinctly see) that such a standard would conflict with many of the dispensations of nature, and with much of what they are accustomed to consider as the Christian creed.

His character does not appear more extraordinary and unusual by the mixture of so much absurdity with so much penetration, than by his tempering such violent ambition, and such enraged fanaticism with so much regard to justice and humanity.

I find the Englishman to be him of all men who stands firmest in his shoes. They have in themselves what they value in their horses, - mettle and bottom.
