Doubt must be no more than vigilance, otherwise it can become dangerous.

This morning I thought, hence lost my bearings, for a good quarter of an hour.

Truth is a standard both of itself and of falsity.

The assertion fallacy ... is the fallacy of confusing the conditions for the performance of the speech act of assertion with the analysis of the meaning of particular words occurring in certain assertions.

Proceeding from ourselves, from our own human consciousness, the only consciousness which we feel from within and in which feeling is identical with being, we attribute some sort of consciousness, more or less dim, to all living things, and even to the stones themselves, for they also live. And the evolution of organic beings is simply the struggle to realize fullness of consciousness through suffering, a continual aspiration to be others without ceasing to be themselves, to break and yet to preserve their proper limits.

The First thing that strikes a traveler in the United States is the innumerable multitude of those who seek to emerge from their original condition; and the second is the rarity of lofty ambition to be observed in the midst of the universally ambitious stir of society. No Americans are devoid of a yearning desire to rise, but hardly any appear to entertain hopes of great magnitude or to pursue very lofty aims. All are constantly seeking to acquire property, power, and reputation.

The particularity (Jeweiligkeit) of the places and their manifoldness are grounded in space, and the particularity of the time points is grounded in time. That basic characteristic of the thing, that essential determination of the thingness of the thing to be this one (je dieses), is grounded in the essence of space and time. Our question "What is a thing?" includes, therefore, the questions "What is space?" and "What is time?" It is customary The particularity (Jeweiligkeit) os the places.

Fleeing from a life of constant insecurity and forced mobility is good preparation for dealing with and resisting the typical forms of exploitation of immaterial labor.

Civilizations die from suicide, not by murder.

Why expect a false theory of the world, i.e. classical physics, to yield a true account of consciousness?

The world is nothing but 'world-as-meaning.'

Sincerity is the end and beginning of things; without sincerity there would be nothing. On this account, the superior man regards the attainment of sincerity as the most excellent thing.

The gods we stand by are the gods we need and can use, the gods whose demands on us are reinforcements of our demands on ourselves and on one another. What I then propose to do is, briefly stated, to test saintliness by common sense, to use human standards to help us decide how far the religious life commends itself as an ideal kind of human activity . ... It is but the elimination of the humanly unfit, and the survival of the humanly fittest, applied to religious beliefs; and if we look at history candidly and without prejudice, we have to admit that no religion has ever in the long run established or proved itself in any other way. Religions have approved themselves; they have ministered to sundry vital needs which they found reigning. When they violated other needs too strongly, or when other faiths came which served the same needs better, the first religions were supplanted.

A man who belongs to some communist or revolutionary society wills certain concrete ends, which imply the will to freedom, and that freedom is willed in community. We will freedom for freedom's sake, and in and through the particular circumstances. And in thus willing freedom, we discover that it depends entirely upon the freedom of others and that the freedom of others depends upon our own.

The physicist who states a law of nature with the aid of a mathematical formula is abstracting a real feature of a real material world, even if he has to speak of numbers, vectors, tensors, state-functions, or whatever to make the abstraction.

Be it well understood, I am free by compulsion, whether I wish to be or not. Freedom is not an activity pursued by an entity that, apart from and previous to such pursuit, is already possessed of a fixed being. To be free means to be lacking in constitutive identity, not to have subscribed to a determined being, to be able to be other than what one was, to be unable to install oneself once and for all in any given being. The only attribute of the fixed, stable being in the free being is this constitutive instability.

A man is as old as his arteries, and as young as his ideas.

The question here is the same as the question I addressed with regard to madness, disease, delinquency and sexuality. In all of these cases, it was not a question of showing how these objects were for a long time hidden before being finally discovered, nor of showing how all these objects are only wicked illusions or ideological products to be dispelled in the light of reason finally having reached its zenith. It was a matter of showing by what conjunctions a whole set of practices-from the moment they become coordinated with a regime of truth-was able to make what does not exist (madness, disease, delinquency, sexuality, etcetera), nonetheless become something.

A loving heart is the beginning of all knowledge.

The Chinese believe that when there are too many policemen, there can be no individual liberty, when there are too many lawyers, there can be no justice, and when there are too many soldiers, there can be no peace.

Most of the propositions that make up the body of administrative theory today share, unfortunately, this defect of proverbs. For almost every principle one can find an equally plausible and acceptable contradictory principle.

And the central assertion of his philosophy is that this inner realm is the 'spiritual world' and that once man has learned to enter this realm, he realizes that it is not a mere imaginative reflection of the external world, but a world that possesses its own independent reality.

Self-reliance, the height and perfection of man, is reliance on God.

The monopoly of capital becomes a fetter upon the mode of production, which has sprung up and flourished along with, and under it. Centralisation of the means of production and socialisation of labour at last reach a point where they become incompatible with their capitalist integument. This integument is burst asunder. The knell of capitalist private property sounds. The expropriators are expropriated.

If someone is merely ahead of his time, it will catch up to him one day.

When at the beginning of the so-called modern age, at the Renaissance, the pagan sense of religion came to life again, it took the concrete form in the knightly ideal with its codes of conduct of love and honor. But it was a paganism Christianized, baptized. "Woman - la donna - was the divinity enshrined within those savage breasts. Whosoever will investigate the memorials of primitive times will find this ideal of woman in its full force and purity; the Universe is woman.

The age of philosophy in the sense again that we are confronted more and more often with philosophical problems at an everyday level. It is not that you withdraw from daily life into a world of philosophical contemplation. On the contrary, you cannot find your way around daily life itself without answering certain philosophical questions. It is a unique time when everyone is, in a way, forced to be some kind of philosopher.

The highest proof of virtue is to possess boundless power without abusing it.

I am now even more persuaded of the urgent need to study why Socrates was accused. The dislike of philosophy is perennial, and the seeds of the condemnation of Socrates are present at all times, not in the bosoms of pleasure-seekers, who don't give a damn, but in those of high-minded and idealistic persons who do not want to submit their aspirations to examination.

Science must begin with myths, and with the criticism of myths.

The idea that an aim can be reasonable for its own sake-on the basis of virtues that insight reveals it to have in itself-without reference to some kind of subjective gain or advantage, is utterly alien to subjective reason, even where it rises above the consideration of immediate utilitarian values and devotes itself to reflection about the social order as a whole.

Can one be a saint without God?, that's the problem, in fact the only problem, I'm up against today.

For the things we have to learn before we can do, we learn by doing.

By the rude bridge that arched the flood, Their flag to April's breeze unfurled, Here once the embattled farmers stood, And fired the shot heard round the world.

Witness the tragic condition of Russia. The methods of State centralization have paralysed individual initiative and effort; the tyranny of the dictatorship has cowed the people into slavish submission and all but extinguished the fires of liberty; organized terrorism has depraved and brutalized the masses and stifled every idealistic aspiration; institutionalized murder has cheapened human life, and all sense of the dignity of man and the value of life has been eliminated; coercion at every step has made effort bitter, labour a punishment, has turned the whole of existence into a scheme of mutual deceit, and has revived the lowest and most brutal instincts of man. A sorry heritage to begin a new life of freedom and brotherhood.

But with respect to future debt; would it not be wise and just for that nation to declare in the constitution they are forming that neither the legislature, nor the nation itself can validly contract more debt, than they may pay within their own age, or within the term of 19 years.

Hayek fails to account either for the passion among intellectuals for equality, or for the resulting success of socialists and their egalitarian successors in driving the liberal idea from the stage of politics. This passion for equality is not a new thing, and indeed pre-dates socialism by many centuries, finding its most influential expression in the writings of Rousseau. There is no consensus as to how equality might be achieved, what it would consist in if achieved, or why it is so desirable in the first place. But no argument against the cogency or viability of the idea has the faintest chance of being listened to or discussed by those who have fallen under its spell.

Every person I met believes if there is any disagreement between the Koran and science, then the Koran wins. It's just utterly deplorable. These are now British children who are having their minds stuffed with alien rubbish. Occasionally, my colleagues lecturing in universities lament having undergraduate students walk out of their classes when they talk about evolution. This is almost entirely Muslims.

I feel effective, competent, likely to do something positive only when I lie down and abandon myself to an interrogation without object or end.

We have unmistakable proof that throughout all past time, there has been a ceaseless devouring of the weak by the strong.
