One common strategy on which we should all be able to agree is to take steps to reduce the risk of human extinction when those steps are also highly effective in benefiting existing sentient beings. For example, eliminating or decreasing the consumption of animal products will benefit animals, reduce greenhouse gas emissions, and lessen the chances of a pandemic resulting from a virus evolving among the animals crowded into today's factory farms, which are an ideal breeding ground for viruses. That therefore looks like a high-priority strategy.

Seeing therefore they are both [heat and pain] immediately perceived at the same time, and the fire affects you only with one simple, or uncompounded idea, it follows that this same simple idea is both the intense heat immediately perceived, and the pain; and consequently, that the intense heat immediately perceived, is nothing distinct from a particular sort of pain.

Mr. Neo-Angular - I am doing my duty. My ethics are based on dogma, not on feeling. Vertue - I know that a rule is to be obeyed because it is a rule and not because it appeals to my feelings at the moment.

My purpose here is to denounce an idea which seems to be dangerous and false. ... Revolutionary trade unionists and orthodox communists are at one in considering everything that is purely theoretical as bourgeois. ... The culture of a socialist society would be a synthesis of theory and practice; but to synthesize is not the same as to confuse together; it is only contraries that can be synthesized. ... Marx's principal glory is to have rescued the study of societies not only from Utopianism but also and at the same time from empiricism. ... Humanity cannot progress by importing into theoretical study the processes of blind routine and haphazard experiment by which production has so long been dominated. ... The true relation between theory and application only appears when theoretical research has been purged of all empiricism.

To flee vice is the beginning of virtue, and to have got rid of folly is the beginning of wisdom.

We are not necessarily doubting that God will do the best for us; we are wondering how painful the best will turn out to be.

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) The real foundations of his enquiry do not strike a man at all. Unless that fact has at some time struck him. - And this means: we fail to be struck by what, once seen, is most striking and most powerful.

If one prefers to have little with blessing, to have truth with concern, to suffer instead of exulting over imagined victories, then one presumably will not be disposed to praise the knowledge, as if what it bestows were at all proportionate to the trouble it causes, although one would not therefore deny that through its pain it educates a person, if he is honest enough to want to be educated rather than to be deceived, out of the multiplicity to seek the one, out of abundance to seek the one thing needful, as this is plainly and simply offered precisely according to the need for it.

A philosopher of imposing stature doesn't think in a vacuum. Even his most abstract ideas are, to some extent, conditioned by what is or is not known in the time when he lives.

Christianity is most admirably adapted to the training of slaves, to the perpetuation of a slave society; in short, to the very conditions confronting us to-day.... The rulers of the earth have realized long ago what potent poison inheres in the Christian religion. That is the reason they foster it; that is why they leave nothing undone to instill it into the blood of the people. They know only too well that the subtleness of the Christian teachings is a more powerful protection against rebellion and discontent than the club or the gun.

Formerly, it was held by philosophers and mathematicians alike that the proofs in Geometry depended on the figure; nowadays, this is known to be false. In the best books there are no figures at all. The reasoning proceeds by the strict rules of formal logic from a set of axioms laid down to begin with.

Only a neutral, who is indifferent to the stake and perhaps to all stakes, can appreciate aesthetically the grandeur of a fine disaster

Every morning I shall concern myself anew about the boundary Between the love-deed-Yes and the power-deed-No And pressing forward honor reality. We cannot avoid Using power, Cannot escape the compulsion To afflict the world, So let us, cautious in diction And mighty in contradiction, Love powerfully.

You can't worship a spirit in spirit, unless you do it now. Wallowing in the past may be good literature. As wisdom, it's hopeless. Time Regained is Paradise Lost, and Time Lost is Paradise Regained. Let the dead bury their dead. If you want to live at every moment as it presents itself, you've got to die to every other moment.

The strongest bulwark of authority is uniformity; the least divergence from it is the greatest crime. The wholesale mechanisation of modern life has increased uniformity a thousandfold. It is everywhere present, in habits, tastes, dress, thoughts and ideas. Its most concentrated dullness is "public opinion." Few have the courage to stand out against it. He who refuses to submit is at once labelled "queer," "different," and decried as a disturbing element in the comfortable stagnancy of modern life.

Nietzsche's great concept of Yea-saying gave him a notion of purpose that is seen as positive.

The great majority of men and women, in ordinary times, pass through life without ever contemplating or criticising, as a whole, either their own conditions or those of the world at large. They find themselves born into a certain place in society, and they accept what each day brings forth, without any effort of thought beyond what the immediate present requires. Almost as instinctively as the beasts of the field, they seek the satisfaction of the needs of the moment, without much forethought, and without considering that by sufficient effort the whole conditions of their lives could be changed.

Love to his soul gave eyes; he knew things are not as they seem. The dream is his real life; the world around him is the dream.

Let me suggest a theme for you: to state to yourself precisely and completely what that walk over the mountains amounted to for you, - returning to this essay again and again, until you are satisfied that all that was important in your experience is in it. Give this good reason to yourself for having gone over the mountains, for mankind is ever going over a mountain. Don't suppose that you can tell it precisely the first dozen times you try, but at 'em again, especially when, after a sufficient pause, you suspect that you are touching the heart or summit of the matter, reiterate your blows there, and account for the mountain to yourself. Not that the story need be long, but it will take a long while to make it short.

The end of the republic is to enervate and to weaken all other bodies so as to increase its own body.

It may indeed be doubted, whether butcher's meat is any where a necessary of life. Grain and other vegetables, with the help of milk, cheese, and butter, or oil, where butter is not to be had, it is known from experience, can, without any butcher's meat, afford the most plentiful, the most wholesome, the most nourishing, and the most invigorating diet.

In all philosophic theory there is an ultimate which is actual in virtue of its accidents. It is only then capable of characterization through its accidental embodiments, and apart from these accidents is devoid of actuality. In the philosophy of organism this ultimate is termed creativity; and [[God] is its primordial, non-temporal accident. In monistic philosophies, Spinoza's or absolute idealism, this ultimate is God, who is also equivalently termed The Absolute. In such monistic schemes, the ultimate is illegitimately allowed a final, eminent reality, beyond that ascribed to any of its accidents. In this general position the philosophy of organism seems to approximate more to some strains of Indian, or Chinese, thought, than to western Asiatic, or European, thought. One side makes process ultimate; the other side makes fact ultimate.

The voice in my soul in which I will have faith, and for the sake of which I have faith in all else, does not merely command me generally to act, but in every particular situation it declares what I shall do and what leave undone; it accompanies me through every event of my life, and it is impossible for me to contend against it. To listen to it and obey it honestly and impartially, without fear or equivocation, is the business of my existence. My life is no longer an empty I play without truth or significance. It is appointed that what I conscience ordains me shall be done, and for this purpose am I here. I have understanding to know, and power to execute it. By conscience alone comes truth and reality into my representations.

In our fear, we are victims of an aggression of the Future.

I see not the shadow of a reason to conclude that their [the sexes'] virtues should differ in respect to their nature. In fact, how can they, if virtue has only one eternal standard? I must therefore, if I reason consequentially, as strenuously maintain that they must have the same simple direction as that there is a God.

There is nothing more visible than what is secret, and nothing more manifest than what is minute. Therefore the superior man is watchful over himself, when he is alone.

Wit is cultured insolence.

The object before us, to begin with, material production.

Pantheism makes God into a present, real, and material being; empiricism - to which rationalism also belongs - makes God into an absent, remote, unreal, and negative being. Empiricism does not deny God existence, but denies him all positive determinations, because their content is supposed to be only finite and empirical; the infinite cannot, therefore, be an object for man. But the more determinations I deny to a being, the more do I cut it of[ from myself, and the less power and influence do I concede to it over me, the freer do I make myself of it. The more qualities I possess, the more I am for others, and the greater is the extent of my influence and effects. And the more one is, the more one is known to others. Hence, each negation of an attribute of God is a partial atheism, a sphere of godlessness.

I must plunge into the water of doubt again and again.

The advance of liberalism, so-called, in Christianity, during the past fifty years, may fairly be called a victory of healthy-mindedness within the church over the morbidness with which the old hell-fire theology was more harmoniously related. We have now whole congregations whose preachers, far from magnifying our consciousness of sin, seem devoted rather to making little of it. They ignore, or even deny, eternal punishment, and insist on the dignity rather than on the depravity of man. They look at the continual preoccupation of the old-fashioned Christian with the salvation of his soul as something sickly and reprehensible rather than admirable; and a sanguine and 'muscular' attitude, which to our forefathers would have seemed purely heathen, has become in their eyes an ideal element of Christian character. I am not asking whether or not they are right, I am only pointing out the change.

Wisdom: The first error is that of the southern people, and it consists in holding that these eastern and western places are real places. ... give no quarter to that thought, whether it threatens you with fear, or tempts you with hopes. For this is Superstition and all who believe it will come in the end to the swamps to the south and the jungles to the far south.

Self-expression is impossible in relation with other men; their self-expression interferes with it. The greatest heights of self-expression in poetry, music, painting - are achieved by men who are supremely alone.

The man who barely abstains from violating either the person, or the estate, or the reputation of his neighbours, has surely very little positive merit. He fulfils, however, all the rules of what is peculiarly called justice, and does every thing which his equals can with propriety force him to do, or which they can punish him for not doing. We may often fulfil all the rules of justice by sitting still and doing nothing.

Those who have ever valued liberty for its own sake believed that to be free to choose, and not to be chosen for, is an inalienable ingredient in what makes human beings human.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!', but 'That's funny ...'

We reduce things to mere Nature in order that we may 'conquer' them.

I like thought which preserves a whiff of flesh and blood, and I prefer a thousand times an idea rising from sexual tension or nervous depression to empty abstraction.

While we are reading these sentences, this fair modern world seems only a reprint of the Laws of Menu with the gloss of Culluca. Tried by a New England eye, or the mere practical wisdom of modern times, they are the oracles of a race already in its dotage, but held up to the sky, which is the only impartial and incorruptible ordeal, they are of a piece with its depth and serenity, and I am assured that they will have a place and significance as long as there is a sky to test them by.

If therefore my work is negative, irreligious, atheistic, let it be remembered that atheism - at least in the sense of this work - is the secret of religion itself; that religion itself, not indeed on the surface, but fundamentally, not in intention or according to its own supposition, but in its heart, in its essence, believes in nothing else than the truth and divinity of human nature. Preface

As geological time goes, it is but a moment since the human race began and only the twinkling of an eye since the arts of civilization were first invented. In spite of some alarmists, it is hardly likely that our species will completely exterminate itself. And so long as man continues to exist, we may be pretty sure that, whatever he may suffer for a time, and whatever brightness may be eclipsed, he will emerge sooner or later, perhaps strengthened and reinvigorated by a period of mental sleep. The universe is vast and men are but tiny specks on an insignificant planet. But the more we realize our minuteness and our impotence in the face of cosmic forces, the more astonishing becomes what human beings have achieved.

That neither our Thoughts, nor Passions, nor Ideas formed by the Imagination, exist without the Mind, is what every Body will allow. And it seems no less evident that the various Sensations or Ideas imprinted on the Sense... cannot exist otherwise than in a Mind perceiving them... For as to what is said of the absolute Existence of unthinking Things without any relation to their being perceived, that seems perfectly unintelligible. Their Esse is Percipi, nor is it possible they should have any Existence, out of the Minds or thinking Things which perceive them.

The infinite... happens to subsist in a way contrary to what is asserted by others: for the infinite is not that beyond which there is nothing, but it is that of which there is always something beyond. ...But that pertaining to which there is nothing beyond is perfect and whole. ...that of which nothing is absent pertaining to the parts ...the whole is that pertaining to which there is nothing beyond. But that pertaining to which something external is absent, that is not all ...But nothing is perfect which has not an end; and the end is a bound. On this account... Parmenides spoke better than Melissus: for the latter says that the infinite is a whole; but the former, that the whole is finite, and equally balanced from the middle: for to conjoin the infinite with the universe and the whole, is not to connect line with line.

Opposition brings concord. Out of discord comes the fairest harmony.

Nothing deserves to be undone, doubtless because nothing deserved to be done.

God might grant us riches, honours, life, and even health, to our own hurt; for every thing that is pleasing to us is not always good for us. If he sends us death, or an increase of sickness, instead of a cure, Vvrga tua et baculus, tuus ipsa me consolata sunt. "Thy rod and thy staff have comforted me," he does it by the rule of his providence, which better and more certainly discerns what is proper for us than we can do; and we ought to take it in good part, as coming from a wise and most friendly hand.

To say that authority, whether secular or religious, supplies no ground for morality is not to deny the obvious fact that it supplies a sanction.

The most disheartening tendency common among readers is to tear out one sentence from a work, as a criterion of the writer's ideas or personality.

At present we live to impede each other's satisfactions; competition, domestic life, society, what is it all but this? We go somewhere where we are not wanted and where we don't want to go. What else is conventional life? Passivity when we want to be active. So many hours spent every day in passively doing what conventional life tells us, when we would so gladly be at work. And is it a wonder that all individual life is extinguished?

In solitude it is possible to love mankind; in the world, for one who knows the world, there can be nothing but secret or open war.
