I am sitting with a philosopher in the garden; he says again and again "I know that that's a tree", pointing to a tree that is near us. Someone else arrives and hears this, and I tell them: "This fellow isn't insane. We are only doing philosophy."

He [the devil] always sends errors into the world in pairs-pairs of opposites. And he always encourages us to spend a lot of time thinking which is the worse. You see why, of course? He relies on your extra dislike of the one error to draw you gradually into the opposite one. But do not let us be fooled. We have to keep our eyes on the goal and go straight through between both errors. We have no other concern than that with either of them.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a deep ocean of anguish, reaching to the very verge of despair.

If any man will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works. Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom. 16:24-28 (KJV)

There can be no doubt that the Virgin Mary is in heaven. How it happened we do not know.

The core of ethics runs deep in our species and is common to human beings everywhere. It survives the most appalling hardships and the most ruthless attempts to deprive human beings of their humanity. Nevertheless, some people resist the idea that his core has a biological basis which we have inherited from our pre-human ancestors.

They who know the truth are not equal to those who love it, and they who love it are not equal to those who delight in it.

Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe. Thomas answered him, "My Lord and my God!" John 20:27-28

The Sophist demonstrates that everything is true and nothing is true.

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.

Moderation, in the pursuit of honors or riches, is the only security against disappointment and vexation. A wise man, therefore, will prefer the simplicity of rustic life to the magnificence of courts.

In skating over thin ice our safety is our speed.

See that no man know it. 9:30 (KJV) Said to the two blind men.

The things that we can see with our physical eyes are mere shadows of reality. If they appear ugly and ill formed, then what must be the ugliness of the soul in sin, deprived of all light? The soul, like the body, can undergo transformation in appearance. In sin it appears as completely ugly to the beholder. In virtue it shines resplendently before God.

It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God. 4:4 (KJV) Said to Satan. 

It is asserted that beasts have no rights; the illusion is harboured that our conduct, so far as they are concerned, has no moral significance, or, as it is put in the language of these codes, that "there are no duties to be fulfilled towards animals." Such a view is one of revolting coarseness, a barbarism of the West, whose source is Judaism. In philosophy, however, it rests on the assumption, despite all evidence to the contrary, of the radical difference between man and beast,-a doctrine which, as is well known, was proclaimed with more trenchant emphasis by Descartes than by any one else: it was indeed the necessary consequence of his mistakes.

A theologian is born by living, nay dying and being damned, not by thinking, reading, or speculating.

The domination of the public way in which things have been interpreted has already decided upon even the possibilities of being attuned, that is, about the basic way in which Da-sein lets itself be affected by the world. The they prescribes that attunement, it determines what and how one "sees."

Nihilism is not overcome by arguments or analyses; it is tamed by love and care. Any disease of the soul must be conquered by a turning of one's soul.

But it isn't just a matter of faith, but of faith and works. Each is necessary. For the demons also believe you heard the apostle and tremble (Jas 2:19); but their believing doesn't do them any good. Faith alone is not enough, unless works too are joined to it: Faith working through love (Gal 5:6), says the apostle.

There is no kind of harassment that a man may not inflict on a woman with impunity in civilized societies.

A religious creed differs from a scientific theory in claiming to embody eternal and absolutely certain truth, whereas science is always tentative, expecting that modification in its present theories will sooner or later be found necessary, and aware that its method is one which is logically incapable of arriving at a complete and final demonstration.

What most astonishes me in the United States, is not so much the marvelous grandeur of some undertakings, as the innumerable multitude of small ones.

Standing on the bare ground, - my head bathed by the blithe air, and uplifted into infinite space, - all mean egotism vanishes. I become a transparent eye-ball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or particle of God.

What is it, in your opinion, to be a great nobleman? It is to be master of several objects that men covet, and thus to be able to satisfy the wants and the desires of many. It is these wants and these desires that attract them towards you, and that make them submit to you: were it not for these, they would not even look at you; but they hope, by these services... to obtain from you some part of the good which they desire, and of which they see that you have the disposal.

Criticism alone can sever the root of materialism, fatalism, atheism, free-thinking, fanaticism, and superstition, which can be injurious universally; as well as of idealism and skepticism, which are dangerous chiefly to the Schools, and hardly allow of being handed on to the public.

All wars are accordingly so many attempts (not in the intention of man, but in the intention of Nature) to establish new relations among states, and through the destruction or at least the dismemberment of all of them to create new political bodies, which, again, either internally or externally, cannot maintain themselves and which must thus suffer like revolutions; until finally, through the best possible civic constitution and common agreement and legislation in external affairs, a state is created which, like a civic commonwealth, can maintain itself automatically.

Without effort and change, human life cannot remain good. It is not a finished Utopia that we ought to desire, but a world where imagination and hope are alive and active.

Constitutional freedom, as the right of every citizen to have to obey no other law than that to which he has given his consent or approval;

"Optimism," said Cacambo, "What is that?" "Alas!" replied Candide, "It is the obstinacy of maintaining that everything is best when it is worst!

Understanding being nothing else, but conception caused by Speech.

Whatever you see in the more material part of yourself, learn to refer to God and to the invisible part of yourself. In that way, whatever offers itself to the senses will become for you an occasion for the practice of piety.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride or laziness of mind. 

The true is the whole.

History is not like some individual person, which uses men to achieve its ends. History is nothing but the actions of men in pursuit of their ends.

It's funny the respectable names you can give to superstition.

Common sense doesn't have the last word in ethics or anywhere else, but it has, as J. L. Austin said about language, the first word: it should be examined before it is discarded.

There are, indeed, things that cannot be put into words. They make themselves manifest. They are what is mystical.

Wonderful is the depth of Thy oracles, whose surface is before us, inviting the little ones; and yet wonderful is the depth, O my God, wonderful is the depth. It is awe to look into it; and awe of honour, and a tremor of love. The enemies thereof I hate vehemently. Oh, if Thou wouldest slay them with Thy two-edged sword, that they be not its enemies! For thus do I love, that they should be slain unto themselves that they may live unto Thee.

In the natural state no concept of God can arise, and the false one which one makes for himself is harmful. Hence the theory of natural religion can be true only where there is no science; therefore it cannot bind all men together.

But, when the elements have been mingled in the fashion of a man and come to the light of day, or in the fashion of the race of wild beasts or plants or birds, then men say that these come into being; and when they are separated, they call that woeful death. They call it not aright; but I too follow the custom, and call it so myself.

The three great things that govern mankind are reason, passion and superstition. The first governs a few, the two last share the bulk of mankind and possess them in their turns. But superstition most powerfully produces the greatest mischief.

For a man petticoat government is the limit of insolence.

Love with delight discourses in my mind Upon my lady's admirable gifts...Beyond the range of human intellect.

Philosophy is not politics, and we do our best, within our all-too-human limitations, to seek the truth, not to score points against opponents. There is little satisfaction in gaining an easy triumph over a weak opponent while ignoring better arguments against your views. 'Last Generation': A Response, The New York Times, June 16, 2010.

Strength of body is nobility in beasts of burden, strength of character is nobility in men.

It is not for you to know the times or the seasons, which the Father hath put in his own power. But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. 1:7-8 (KJV)

Given that annihilation of nature in its entirety is impossible, and that death and dissolution are not appropriate to the whole mass of this entire globe or star, from time to time, according to an established order, it is renewed, altered, changed, and transformed in all its parts.

The moment we no longer have a free press, anything can happen. What makes it possible for a totalitarian or any other dictatorship to rule is that people are not informed; how can you have an opinion if you are not informed? If everybody always lies to you, the consequence is not that you believe the lies, but rather that nobody believes anything any longer. This is because lies, by their very nature, have to be changed, and a lying government has constantly to rewrite its own history. On the receiving end you get not only one lie - a lie which you could go on for the rest of your days - but you get a great number of lies, depending on how the political wind blows. And a people that no longer can believe anything cannot make up its mind. It is deprived not only of its capacity to act but also of its capacity to think and to judge. And with such a people you can then do what you please.

Solicitation and effort or conation belong properly to animate beings alone. When they are attributed to other things, they must be taken in a metaphorical sense; but a philosopher should abstain from metaphor.
