Now as we call every thing custom, which proceeds from a past repetition, without any new reasoning or conclusion, we may establish it as a certain truth, that all the belief, which follows upon any present impression, is deriv'd solely from that origin.

There is not a negro from the coast of Africa who does not, in this respect, possess a degree of magnanimity which the soul of his sordid master is too often scarce capable of conceiving. Fortune never exerted more cruelly her empire over mankind, than when she subjected those nations of heroes to the refuse of the jails of Europe, to wretches who possess the virtues neither of the countries which they come from, nor of those which they go to, and whose levity, brutality, and baseness, so justly expose them to the contempt of the vanquished.

What strength belongs to every plant and animal in nature. The tree or the brook has no duplicity, no pretentiousness, no show. It is, with all its might and main, what it is, and makes one and the same impression and effect at all times. All the thoughts of a turtle are turtles, and of a rabbit, rabbits. But a man is broken and dissipated by the giddiness of his will; he does not throw himself into his judgments; his genius leads him one way but 't is likely his trade or politics in quite another.

Hearken with your ears to these best counsels,Reflect upon them with illumined judgment.Let each one choose his creed with that freedom of choice each must have at great events.

Advancing bourgeois society liquidates memory, time, recollection as irrational leftovers of the past.

How can I, who was not able to retain my own past, hope to save that of another?

The perfection of a thing does not annul its existence, but, on the contrary, asserts it. Imperfection, on the other hand, does annul it ; therefore we cannot be more certain of the existence of anything, than of the existence of a being absolutely infinite or perfect-that is, of God. For inasmuch as his essence excludes all imperfection, and involves absolute perfection, all cause for doubt concerning his existence is done away, and the utmost certainty on the question is given. This, I think, will be evident to every moderately attentive reader.

Animals and plants are living effects of Nature; this Nature ... is none other than God in things... Diverse living things represent diverse divinities and diverse powers, which, besides the absolute being they possess, obtain the being communicated to all things according to their capacity and measure. Whence all of God is in all things (although not totally, but in some more abundantly and in others less) ... Think thus, of the sun in the crocus, in the narcissus, in the heliotrope, in the rooster, in the lion.... To the extent that one communicates with Nature, so one ascends to Divinity through Nature.

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.

Even those who have renounced Christianity and attack it, in their inmost being still follow the Christian ideal, for hitherto neither their subtlety nor the ardor of their hearts has been able to create a higher ideal of man and of virtue than the ideal given by Christ.

A life devoted to science is therefore a happy life, and its happiness is derived from the very best sources that are open to dwellers on this troubled and passionate planet.

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.

If we make a couple of discoveries here and there we need not believe things will go on like this for ever.... Just as we hit water when we dig in the earth, so we discover the incomprehensible sooner or later.

My appetite comes to me while eating.

In the dominant Western religious system, the love of God is essentially the same as the belief in God, in God's existence, God's justice, God's love. The love of God is essentially a thought experience. In the Eastern religions and in mysticism, the love of God is an intense feeling experience of oneness, inseparably linked with the expression of this love in every act of living.

All media work us over completely. They are so pervasive in their personal, political, economic, aesthetic, psychological, moral, ethical, and social consequences that they leave no part of us untouched, unaffected, unaltered. The medium is the massage. Any understanding of social and cultural change is impossible without a knowledge of the way media work as environments. All media are extensions of some human faculty - psychic or physical.

I consider as lovers of books not those who keep their books hidden in their store-chests and never handle them, but those who, by nightly as well as daily use thumb them, batter them, wear them out, who fill out all the margins with annotations of many kinds, and who prefer the marks of a fault they have erased to a neat copy full of faults.

Power is not opposed to freedom. It is precisely freedom that distinguishes power from violence or coercion.

In the United States, the majority undertakes to supply a multitude of ready-made opinions for the use of individuals, who are thus relieved from the necessity of forming opinions of their own.

The similarity between Marxism and neoconservativism might be expressed in the following way: both perspectives say that certain injustices can't be cured under our present system of political democracy and mixed economy. The Marxist concludes that we have to overthrow the present system and the neoconservative concludes that we have to live with the injustices. But they are both wrong.

Most people live, whether physically, intellectually or morally, in a very restricted circle of their potential being. They make use of a very small portion of their possible consciousness, and of their soul's resources in general, much like a man who, out of his whole bodily organism, should get into a habit of using and moving only his little finger. Great emergencies and crises show us how much greater our vital resources are than we had supposed.

Here we must make one of those inductive applications of the law of continuity which have produced such great results in all of the positive sciences. We must extend the law of insistency into the future. Plainly, the insistency of a future idea with reference to the present is a quantity affected by the minus sign; for it is the present that affects the future, if there be any effect, not the future that affects the present.

When we reflect on the long and dense night in which France and all Europe have remained plunged by their governments and their priests, we must feel less surprise than grief at the bewilderment caused by the first burst of light that dispels the darkness.

The tool, as we have seen, is not exterminated by the machine.

My lectures are published and not published; they will be intelligible to those who heard them, and to none beside.

Christianity has functioned for the normative self-understanding of modernity as more than a mere precursor or a catalyst. Egalitarian universalism, from which sprang the ideas of freedom and social solidarity, of an antonomous conduct of life and emancipation, of the individual morality of conscience, human rights, and democracy, is the direct heir to the judaic ethic of justice and the Christian ethic of love. This legacy, substantially unchanged, has been the object of continual critical appropriation and reinterpretation. To this day, there is no alternative to it. And in the light of the current challenges of a postnational constellation, we continue to draw on the substance of this heritage. Everything else is just idle postmodern talk.

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

I am a utilitarian. I am also a vegetarian. I am a vegetarian because I am a utilitarian.

I find that the whiter my hair becomes the more ready people are to believe what I say.

Each of our senses makes its own space, but no sense can function in isolation. Only as sight relates the touch, or kinaesthesia, or sound, can the eye see.

Put in a nut-shell, my thesis amounts to this. The repeated attempts made by Rudolf Carnap to show that the demarcation between science and metaphysics coincides with that between sense and nonsense have failed. The reason is that the positivistic concept of 'meaning' or 'sense' (or of verifiability, or of inductive confirmability, etc.) is inappropriate for achieving this demarcation - simply because metaphysics need not be meaningless even though it is not science. In all its variations demarcation by meaninglessness has tended to be at the same time too narrow and too wide: as against all intentions and all claims, it has tended to exclude scientific theories as meaningless, while failing to exclude even that part of metaphysics which is known as 'rational theology'.

For such is the nature of men, that howsoever they may acknowledge many others to be more witty, or more eloquent, or more learned; Yet they will hardly believe there be many so wise as themselves: For they see their own wit at hand, and other men's at a distance.

God functions like a stabilizer of time.

Poetry - No definition of poetry is adequate unless it be poetry itself. The most accurate analysis by the rarest wisdom is yet insufficient, and the poet will instantly prove it false by setting aside its requisitions. It is indeed all that we do not know. The poet does not need to see how meadows are something else than earth, grass, and water, but how they are thus much. He does not need discover that potato blows are as beautiful as violets, as the farmer thinks, but only how good potato blows are. The poem is drawn out from under the feet of the poet, his whole weight has rested on this ground. It has a logic more severe than the logician's. You might as well think to go in pursuit of the rainbow, and embrace it on the next hill, as to embrace the whole of poetry even in thought.

Even after his conversion, the true 'apostate' is not primarily committed to the positive contents of his new belief and to the realization of its aims. He is motivated by the struggle against the old belief and lives on for its negation. The apostate does not affirm his new convictions for their own sake; he is engaged in a continuous chain of acts of revenge against his own spiritual past. In reality he remains a captive of this past, and the new faith is merely a handy frame of reference for negating and rejecting the old. As a religious type, the apostate is therefore at the opposite pole from the 'resurrected,' whose life is transformed by a new faith which is full of intrinsic meaning and value.

Only the dead have seen the end of war.

Great novelists are philosopher novelists, that is, the contrary of thesis-writers.

As for 'taking sides' - the choice, it seems to me, is no longer between two users of violence, two systems of dictatorship. Violence and dictatorship cannot produce peace and liberty; they can only produce the results of violence and dictatorship, results with which history has made us only too sickeningly familiar. The choice now is between militarism and pacifism. To me, the necessity of pacifism seems absolutely clear.

The first duty of a man is the seeking after and the investigation of truth.

Never say, and never take seriously anyone who says, "I cannot believe that so-and-so could have evolved by gradual selection". I have dubbed this kind of fallacy "the Argument from Personal Incredulity". Time and again, it has proven the prelude to an intellectual banana-skin experience.

Since property here exists in the form of stock, its movement and transfer become purely a result of gambling on the stock exchange, where the little fish are swallowed by the sharks and the lambs by the stock exchange wolves.

I believe in the salvation of humanity, in the future of cyanide . . .

There is a physical relation between physical things. But it is different with commodities.

You do not attain to knowledge by remaining on the shore and watching the foaming waves, you must make the venture and cast yourself in, you must swim, alert and with all your force, even if a moment comes when you think you are losing consciousness; in this way, and in no other, do you reach anthropological insight.

The stars are scattered all over the sky like shimmering tears, there must be great pain in the eye from which they trickled.

We are and irrefutable arbiters of value, and in the world of value Nature is only a part. Thus in this world we are greater than Nature. In the world of values, Nature in itself is neutral, neither good nor bad deserving of neither admiration nor censure. It is we who create value and our desires which confer value. In this realm we are kings, and we debase our kingship if we bow down to Nature. It is for us to determine our good life, not for Nature - not even for Nature personified as God.

In ordinary visual perception, we see by means of light; we distinguish by means of reflected and refracted colors. But in ordinary perception, this medium of color is mixed, adulterated. While we see, we also hear; we feel pressures, and heat and cold. In a painting, color renders the scene without these alloys and impurities. They are part of the dross that is squeezed out and left behind in an act of intensified expression. The medium becomes color alone, and since color alone must now carry the qualities of movement, touch, sound, etc., that are present physically on their own account in ordinary vision, the expressiveness and energy of color are enhanced.
