We are accustomed to speak of ideas as reproduced, as passed from mind to mind, as similar or dissimilar to one another, and, in short, as if they were substantial things; nor can any reasonable objection be raised to such expressions. But taking the word "idea" in the sense of an event in an individual consciousness, it is clear that an idea once past is gone forever, and any supposed recurrence of it is another idea. These two ideas are not present in the same state of consciousness, and therefore cannot possibly be compared.

There is no tyranny in the world more hateful than that of ideas. Ideas bring ideophobia, and the consequence is that people begin to persecute their neighbors in the name of ideas. I loathe and detest all labels, and the only label that I could now tolerate would be that of ideoclast or idea breaker.

Since the law is good, the will, which is hostile to it, cannot be good.

No man can justly censure or condemn another, because indeed no man truly knows another.

What is to prevent one from telling truth as he laughs, even as teachers sometimes give cookies to children to coax them into learning their A B C?

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.

The most elementary form of rebellion, paradoxically, expresses an aspiration for order.

Hypocrisy, of course, delights in the most sublime speculations; for, never intending to go beyond speculation, it costs nothing to have it magnificent.

The past alone is truly real: the present is but a painful, struggling birth into the immutable being of what is no longer. Only the dead exist fully. The lives of the living are fragmentary, doubtful, and subject to change; but the lives of the dead are complete, free from the sway of Time, the all but omnipotent lord of the world. Their failures and successes, their hopes and fears, their joys and pains, have become eternal-our efforts cannot now abate one jot of them. Sorrows long buried in the grave, tragedies of which only a fading memory remains, loves immortalized by Death's hallowing touch these have a power, a magic, an untroubled calm, to which no present can attain. ...On the banks of the river of Time, the sad procession of human generations is marching slowly to the grave; in the quiet country of the Past, the march is ended, the tired wanderers rest, and the weeping is hushed.

What, then, is the animal? First of all, a system of plant-souls. The unity of those plant-souls, which unity nature itself produces, is the soul of the animal. Its world is therefore partly that of the plants - its nourishment, for instance, it receives partly through synthesis from vegetable, and through analysis from animal nature - and partly that of the animals, whereof we shall speak directly. Each product of nature is an organically in-itself completed totality in space, like the plant. Hence, the unknown x which we are looking for must also be such a whole or totality, and in so far it must also have a principle of organization, a sphere and central point of this organization ; in short, the same which we have called the soul of the plant, which thus remains common to both. ... The animal is a system of plant-souls, and the plant is a separated, isolated part of an animal. Both reciprocally affect each other.

The trouble with fiction... is that it makes too much sense. Reality never makes sense.

Animal Liberation is Human Liberation too.

I could not be true and constant to the argument I handle, if I were not willing to go beyond others; but yet not more willing than to have others go beyond me again: which may the better appear by this, that I have propounded my opinions naked and unarmed, not seeking to preoccupate the liberty of men's judgments by confutations.

The RIGHT OF NATURE, which Writers commonly call Jus Naturale, is the Liberty each man hath, to use his own power, as he will himself, for the preservation of his own Nature; that is to say, of his own Life; and consequently, of doing any thing, which in his own Judgement, and Reason, he shall conceive to be the aptest means thereunto.

The superior man examines his heart, that there may be nothing wrong there, and that he may have no cause for dissatisfaction with himself. That wherein the superior man cannot be equaled is simply this, his work which other men cannot see.

That is why St. John of the Cross calls faith a night. With those who have received a Christian education, the lower parts of the soul become attached to these mysteries when they have no right at all to do so. That is why such people need a purification of which St. John of the Cross describes the stages. Atheism and incredulity constitute an equivalent of such a purification.

Tears do not burn except in solitude.

We should not pretend to understand the world only by the intellect; we apprehend it just as much by feeling. Therefore, the judgment of the intellect is, at best, only the half of truth, and must, if it be honest, also come to an understanding of its inadequacy. Variant translation: We should not pretend to understand the world only by the intellect. The judgement of the intellect is only part of the truth.

We produce enough food to feed everyone while millions starve. Restaurants discard edible food, grocery stores destroy expiring products, farms let produce rot rather than lower prices. Food waste coexists with hunger because feeding people is less profitable than maintaining scarcity.

The tolls for the maintenance of a high road, cannot with any safety be made the property of private persons.

Let the public good overcome all private and selfish regards of every kind and degree; though in truth, even private and selfish regards, and every man's own interest, will be best promoted by the preservation of peace.

You don't have a soul. You are a soul. You have a body.

I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation.

We can only learn to love by loving.

Yes, you see the Trinity if you see charity.

"And your education! Is not that also social, and determined by the social conditions under which you educate, by the intervention, direct or indirect, of society, by means of schools, etc.? The Communists have not invented the intervention of society in education; they do but seek to alter the character of that intervention, and to rescue education from the influence of the ruling class."

There's only one corner of the universe you can be certain of improving, and that's your own self.

When animus and anima meet, the animus draws his sword of power and the anima ejects her poison of illusion and seduction. The outcome need not always be negative, since the two are equally likely to fall in love (a special instance of love at first sight).

Pursued by our origins...we all are.

Americans combine to give fêtes, found seminaries, build churches, distribute books, and send missionaries to the antipodes. Hospitals, prisons, and schools take shape in that way. Finally, if they want to proclaim a truth or propagate some feeling by the encouragement of a great example, they form an association. In every case, at the head of any new undertaking, where in France you would find the government or in England some territorial magnate, in the United States you are sure to find an association. I have come across several types of association in America of which, I confess, I had not previously the slightest conception, and I have often admired the extreme skill they show in proposing a common object for the exertions of very many and in inducing them voluntarily to pursue it.

And the Science of them, is the true and onely Moral Philosophy. For Moral Philosophy is nothing else but the Science of what is Good, and Evill, in the conversation, and Society of mankind. Good, and Evill, are names that signify our Appetites, and Aversions; which in different tempers, customes, and doctrines of men, are different.

If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much - and then performed so little.

Now when God sends forth his holy Gospel, He deals with us in a twofold manner, the first outwardly, then inwardly. Outwardly he deals with us through the oral word of the Gospel and through material sings, that is, baptism adndthe sacrament of the altar. Inwardly He deals with us through the Holy spirit, faith, and other gifts. But whatever their measure of order the outward factors should and must procede. The inward experience follows and is effected by the outward. God has determined to give the inward to no one except through the outward.

All religions promise a reward for excellences of the will or heart, but none for excellences of the head or understanding.

But such is the nature of the human mind, that it always lays hold on every mind that approaches it; and as it is wonderfully fortified by an unanimity of sentiments, so is it shocked and disturbed by any contrariety. Hence the eagerness, which most people discover in a dispute; and hence their impatience of opposition, even in the most speculative and indifferent opinions.

I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. I am the good shepherd: the good shepherd giveth his life for the sheep.

What chance has Vulcan against Roberts & Co., Jupiter against the lightning-rod and Hermes against the Credit Mobilier? All mythology overcomes and dominates and shapes the forces of nature in the imagination and by the imagination; it therefore vanishes with the advent of real mastery over them.

The extreme nature of dominant-end views is often concealed by the vagueness and ambiguity of the end proposed.

The tyrant has arisen, and the king and oligarchy and aristocracy and democracy, because men are not contented with that one perfect ruler, and do not believe that there could ever be any one worthy of such power or willing and able by ruling with virtue and knowledge to dispense justice and equity rightly to all, but that he will harm and kill and injure any one of us whom he chooses on any occasion, since they admit that if such a man as we describe should really arise, he would be welcomed and would continue to dwell among them, directing to their weal as sole ruler a perfectly right form of government. But, as the case now stands, since, as we claim, no king is produced in our states who is, like the ruler of the bees in their hives, by birth pre-eminently fitted from the beginning in body and mind, we are obliged, as it seems, to follow in the track of the perfect and true form of government by coming together and making written laws.

These numerous points at which money is withdrawn from circulation and accumulated in numerous individual hoards or potential money-capitals appears as so many obstacles to circulation, because they immobilise the money and deprive it of its capacity to circulate for a certain time.

We used to pay too little attention to utopias, or even disregard them altogether, saying with regret they were impossible of realisation. Now indeed they seem to be able to be brought about far more easily than we supposed, and we are actually faced by an agonising problem of quite another kind: how can we prevent their final realisation? ... Utopias are more realisable than those 'realist politics' that are only the carefully calculated policies of office-holders, and towards utopias we are moving. But it is possible that a new age is already beginning, in which cultured and intelligent people will dream of ways to avoid ideal states and to get back to a society that is less 'perfect' and more free.

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

There are two famous labyrinths where our reason very often goes astray. One concerns the great question of the free and the necessary, above all in the production and the origin of Evil. The other consists in the discussion of continuity, and of the indivisibles which appear to be the elements thereof, and where the consideration of the infinite must enter in.

In a single second we do away with all seconds; God himself could not do as much.

This world belongs to the energetic.

It may indeed be said that since Philosophy began to take a place in Germany, it has never looked so badly as at the present time - never have emptiness and shallowness overlaid it so completely, and never have they spoken and acted with such arrogance, as though all power were in their hands ! To combat the shallowness, to strive with German earnestness and honesty, to draw Philosophy out of the solitude into which it has wandered - to do such work as this we may hope that we are called by the higher spirit of our time.

The sky is the daily bread of the eyes.

There are two kinds of truths: those of reasoning and those of fact. The truths of reasoning are necessary and their opposite is impossible; the truths of fact are contingent and their opposites are possible.

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?

Animals destitute of reason live with their own kind in a state of social amity. Elephants herd together; sheep and swine feed in flocks; cranes and crows take their flight in troops; storks have their public meetings to consult previously to their emigration, and feed their parents when unable to feed themselves; dolphins defend each other by mutual assistance; and everybody knows, that both ants and bees have respectively established by general agreement, a little friendly community.
