I have described religion as the metaphysics of the people.

Thus, because Christian morals leave animals out of consideration ... therefore in philosophical morals they are of course at once outlawed; they are merely "things," simply means to ends of any sort; and so they are good for vivisection, for deer-stalking, bull-fights, horse-races, etc., and they may be whipped to death as they struggle along with heavy quarry carts. Shame on such a morality ... which fails to recognize the Eternal Reality immanent in everything that has life, and shining forth with inscrutable significance from all eyes that see the sun!

The effect of music is so very much more powerful and penetrating than is that of the other arts, for these others speak only of the shadow, but music of the essence.

A man's body and the needs of his body are now everywhere treated with a tender indulgence. Is the thinking mind then, to be the only thing that is never to obtain the slightest measure of consideration or protection, to say nothing of respect?

If a person is stupid, we excuse him by saying that he cannot help it; but if we attempted to excuse in precisely the same way the person who is bad, we should be laughed at.

Childish and altogether ludicrous is what you yourself are and all philosophers; and if a grown-up man like me spends fifteen minutes with fools of this kind, it is merely a way of passing the time. I've now got more important things to do. Goodbye!

If there is anything in the world that can really be called a man's property, it is surely that which is the result of his mental activity.

Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.

My body and my will are one.

Philosophy of religion ... really amounts to ... philosophizing on certain favorite assumptions that are not confirmed at all.

Boundless compassion for all living beings is the surest and most certain guarantee of pure moral conduct, and needs no casuistry. Whoever is filled with it will assuredly injure no one, do harm to no one, encroach on no man's rights; he will rather have regard for every one, forgive every one, help every one as far as he can, and all his actions will bear the stamp of justice and loving-kindness. ... In former times the English plays used to finish with a petition for the King. The old Indian dramas close with these words: "May all living beings be delivered from pain." Tastes differ; but in my opinion there is no more beautiful prayer than this.

This art is music. It stands quite apart from all the others. In it we do not recognize the copy, the repetition, of any Idea of the inner nature of the world. Yet it is such a great and exceedingly fine art, its effect on man's innermost nature is so powerful, and it is so completely and profoundly understood by him in his innermost being as an entirely universal language, whose distinctness surpasses even that of the world of perception itself, that in it we certainly have to look for more than that.

Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served.

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

A reproach can only hurt if it hits the mark. Whoever knows that he does not deserve a reproach can treat it with contempt.

Change alone is eternal, perpetual, immortal.

No difference of rank, position, or birth, is so great as the gulf that separates the countless millions who use their head only in the service of their belly, in other words, look upon it as an instrument of the will, and those very few and rare persons who have the courage to say: No! my head is too good for that; it shall be active only in its own service; it shall try to comprehend the wondrous and varied spectacle of this world and then reproduce it in some form, whether as art or as literature, that may answer to my character as an individual.

We see in tragedy the noblest men, after a long conflict and suffering, finally renounce forever all the pleasure of life and the aims till then pursued so keenly, or cheerfully and willingly give up life itself.

The cheapest sort of pride is national pride; for if a man is proud of his own nation, it argues that he has no qualities of his own of which he can be proud; otherwise he would not have recourse to those which he shares with so many millions of his fellowmen. The man who is endowed with important personal qualities will be only too ready to see clearly in what respects his own nation falls short, since their failings will be constantly before his eyes. But every miserable fool who has nothing at all of which he can be proud adopts, as a last resource, pride in the nation to which he belongs; he is ready and glad to defend all its faults and follies tooth and nail, thus reimbursing himself for his own inferiority.

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.

For what is modesty but hypocritical humility, by means of which, in a world swelling with vile envy, a man seeks to beg pardon for his excellences and merits from those who have none? For whoever attributes no merit to himself because he really has none is not modest, but merely honest.

To be a philosopher, that is to say, a lover of wisdom (for wisdom is nothing but truth), it is not enough for a man to love truth, in so far as it is compatible with his own interest, with the will of his superiors, with the dogmas of the church, or with the prejudices and tastes of his contemporaries; so long as he rests content with this position, he is only a philautos, not a philosophos [a lover of self, not a lover of wisdom]. For this title of honor is well and wisely conceived precisely by its stating that one should love the truth earnestly and with one's whole heart, and thus unconditionally and unreservedly, above all else, and, if need be, in defiance of all else. Now the reason for this is the one previously stated that the intellect has become free, and in this state it does not even know or understand any other interest than that of truth.

At the age of five years to enter a spinning-cotton or other factory, and from that time forth to sit there daily, first ten, then twelve, and ultimately fourteen hours, performing the same mechanical labour, is to purchase dearly the satisfaction of drawing breath. But this is the fate of millions, and that of millions more is analogous to it.

Christianity taught only what the whole of Asia knew already long before and even better.

A mother gave her children Aesop's fables to read, in the hope of educating and improving their minds; but they very soon brought the book back, and the eldest, wise beyond his years, delivered himself as follows: This is no book for us; it's much too childish and stupid. You can't make us believe that foxes and wolves and ravens are able to talk; we've got beyond stories of that kind! In these young hopefuls you have the enlightened Rationalists of the future.

That books do not take the place of experience, and that learning is no substitute for genius, are two kindred phenomena; their common ground is that the abstract can never take the place of the perceptive.

No doubt, when modesty was made a virtue, it was a very advantageous thing for the fools, for everybody is expected to speak of himself as if he were one.

Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he, who is cruel to living creatures, cannot be a good man. Moreover, this compassion manifestly flows from the same source whence arise the virtues of justice and loving-kindness towards men.

The composer reveals the innermost nature of the world, and expresses the profoundest wisdom in a language that his reasoning faculty does not understand, just as a magnetic somnambulist gives information about things of which she has no conception when she is awake. Therefore in the composer, more than in any other artist, the man is entirely separate and distinct from the artist.

The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.

...this our world, which is so real, with all its suns and milky ways is-nothing.

How every line is of such strong, determined, and consistent meaning! And on every page we encounter deep, original, lofty thoughts, while the whole world is suffused with a high and holy seriousness.

In a field of ripening corn I came to a place which had been trampled down by some ruthless foot; and as I glanced amongst the countless stalks, every one of them alike, standing there so erect and bearing the full weight of the ear, I saw a multitude of different flowers, red and blue and violet. How pretty they looked as they grew there so naturally with their little foliage! But, thought I, they are quite useless; they bear no fruit; they are mere weeds, suffered to remain only because there is no getting rid of them. And yet, but for these flowers, there would be nothing to charm the eye in that wilderness of stalks. They are emblematic of poetry and art, which, in civic life-so severe, but still useful and not without its fruit-play the same part as flowers in the corn.

There is only one inborn erroneous notion ... that we exist in order to be happy ... So long as we persist in this inborn error ... the world seems to us full of contradictions. For at every step, in great things and small, we are bound to experience that the world and life are certainly not arranged for the purpose of maintaining a happy existence ... hence the countenances of almost all elderly persons wear the expression of ... disappointment.

Pride is an established conviction of one's own paramount worth in some particular respect, while vanity is the desire of rousing such a conviction in others, and it is generally accompanied by the secret hope of ultimately coming to the same conviction oneself. Pride works from within; it is the direct appreciation of oneself. Vanity is the desire to arrive at this appreciation indirectly, from without.

Europeans are awakening more and more to a sense that beasts have rights, in proportion as the strange notion is being gradually overcome and outgrown, that the animal kingdom came into existence solely for the benefit and pleasure of man. This view, with the corollary that non-human living creatures are to be regarded merely as things, is at the root of the rough and altogether reckless treatment of them, which obtains in the West.

This actual world of what is knowable, in which we are and which is in us, remains both the material and the limit of our consideration.

If, while hurrying ostensibly to the temple of truth, we hand the reins over to our personal interests which look aside at very different guiding stars, for instance at the tastes and foibles of our contemporaries, at the established religion, but in particular at the hints and suggestions of those at the head of affairs, then how shall we ever reach the high, precipitous, bare rock whereon stands the temple of truth?

Whoever heard me assert that the grey cat playing just now in the yard is the same one that did jumps and tricks there five hundred years ago will think whatever he likes of me, but it is a stranger form of madness to imagine that the present-day cat is fundamentally an entirely different one.

And O! how the mind is here washed clean of all its early ingrafted Jewish superstition ! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.

The charlatan takes very different shapes according to circumstances; but at bottom he is a man who cares nothing about knowledge for its own sake, and only strives to gain the semblance of it that he may use it for his own personal ends, which are always selfish and material.

Life is a business that does not cover the costs.

On the other hand, the cheapest form of pride is national pride; for the man affected therewith betrays a want of individual qualities of which he might be proud, since he would not otherwise resort to that which he shares with so many millions. The man who possesses outstanding personal qualities will rather see most clearly the faults of his own nation, for he has them constantly before his eyes. But every miserable fool, who has nothing in the world whereof he could be proud, resorts finally to being proud of the very nation to which he belongs. In this he finds compensation and is now ready and thankful to defend, ... all the faults and follies peculiar to it.

Let us cultivate our garden.

I cannot imagine how the clockwork of the universe can exist without a clockmaker.

All men would then be necessarily equal, if they were without needs. It is the poverty connected with our species which subordinates one man to another. It is not inequality which is the real misfortune, it is dependence.

In every province, the chief occupations, in order of importance, are lovemaking, malicious gossip, and talking nonsense.

Virtue supposes liberty, as the carrying of a burden supposes active force. Under coercion there is no virtue, and without virtue there is no religion. Make a slave of me, and I shall be no better for it. Even the sovereign has no right to use coercion to lead men to religion, which by its nature supposes choice and liberty. My thought is no more subject to authority than is sickness or health.

Morality is everywhere the same for all men, therefore it comes from God; sects differ, therefore they are the work of men.

A testimony is sufficient when it rests on: 1st. A great number of very sensible witnesses who agree in having seen well. 2d. Who are sane, bodily and mentally. 3d. Who are impartial and disinterested. 4th. Who unanimously agree. 5th. Who solemnly certify to the fact.
