Humans already massively intervene in Nature, whether through habitat destruction, captive breeding programs for big cats, "rewilding", etc. So the question is not whether humans should "interfere", but rather what ethical principles should govern our interventions.

There is no alleviation for the sufferings of mankind except veracity of thought and of action, and the resolute facing of the world as it is, when the garment of make-believe, by which pious hands have hidden its uglier features, is stripped off.

We Shall Naturally look round in vain the macrophysical world for acausal events, for the simple reason that we cannot imagine events that are connected non-causally and are capable of a non-causal explanation. But that does not mean that such events do not exist... The so-called "scientific view of the world" based on this can hardly be anything more than a psychologically biased partial view which misses out all those by no means unimportant aspects that cannot be grasped statistically.

I suppose it is written that any one who sets up for a bit of a philosopher, must contradict himself to his very face. For here have I fairly talked myself into thinking that we have the whole thing before us at last; that there is no answer to the mystery, except that there are as many as you please; that there is no centre to the maze because, like the famous sphere, its centre is everywhere; and that agreeing to differ with every ceremony of politeness, is the only "one undisturbed song of pure concent" to which we are ever likely to lend our musical voices.

Scott does this still better than Wordsworth, and a very second-rate landscape does it more effectually than any poet. What made Wordsworth's poems a medicine for my state of mind, was that they expressed, not mere outward beauty, but states of feeling, and of thought coloured by feeling, under the excitement of beauty. They seemed to be the very culture of the feelings, which I was in quest of. In them I seemed to draw from a Source of inward joy, of sympathetic and imaginative pleasure, which could be shared in by all human beings; which had no connexion with struggle or imperfection, but would be made richer by every improvement in the physical or social condition of mankind. From them I seemed to learn what would be the perennial sources of happiness, when all the greater evils of life shall have been removed. And I felt myself at once better and happier as I came under their influence.

Since in the Middle Ages the psychic relation to woman was expressed in the collective worship of Mary, the image of woman lost a value to which human beings had a natural right. This value could find its natural expression only through individual choice, and it sank into the unconscious when the individual form of expression was replaced by a collective one. In the unconscious the image of woman received an energy charge that activated the archaic and infantile dominants. And since all unconscious contents, when activated by dissociated libido, are projected upon the external object, the devaluation of the real woman was compensated by daemonic features. She no longer appeared as an object of love, but as a persecutor or witch. The consequence of increasing Mariolatry was the witch hunt, that indelible blot on the later Middle Ages.

Seduction is the world's elementary dynamic... All this has changed significantly for us, at least in appearance. For what has happened to good and evil? Seduction hurls them against one another, and unites them beyond meaning, in a paroxysm [sudden outbreak of emotion] of intensity and charm.

Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality.

For Warre, consisteth not in Battell onely, or the act of fighting; but in a tract of time, wherein the Will to contend by Battell is sufficiently known: and therefore the notion of Time, is to be considered in the nature of Warre; as it is in the nature of Weather.

Truth lives, in fact, for the most part on a credit system. Our thoughts and beliefs 'pass,' so long as nothing challenges them, just as bank-notes pass so long as nobody refuses them.

I believe that the nature of man is a contradiction rooted in the conditions of human existence that requires a search for solutions, which in their turn create new contradictions and now the need for answers. I believe that every answer to these contradictions can really satisfy the condition of helping man to overcome the sense of separation and to achieve a sense of agreement, of unity, and of belonging. I believe that in every answer to these contradictions, man has the possibility of choosing only between going forward or going back; these choices, which are translated into specific actions, are means toward the regressing or toward the progressing of the humanity that is in us.

I don't deserve a share in governing a hen-roost, much less a nation. Nor do most people - all the people who believe advertisements, and think in catchwords and spread rumors. The real reason for democracy is just the reverse. Mankind is so fallen that no man can be trusted with unchecked power over his fellows. Aristotle said that some people were only fit to be slaves. I do not contradict him. But I reject slavery because I see no men fit to be masters.

If truth were not boring, science would have done away with God long ago. But God as well as the saints is a means to escape the dull banality of truth.

They all attributed the peaceful dominion of religion in their country mainly to the separation of church and state. I do not hesitate to affirm that during my stay in America I did not meet a single individual, of the clergy or the laity, who was not of the same opinion on this point.

Truth will do well enough if left to shift for herself. She seldom has received much aid from the power of great men to whom she is rarely known & seldom welcome. She has no need of force to procure entrance into the minds of men. Error indeed has often prevailed by the assistance of power or force. Truth is the proper & sufficient antagonist to error.

Use these rules then, and trouble thyself about nothing else.

That by any series of changes a protozoon should ever become a mammal, seems to those who are not familiar with zoology, and who have not seen how clear becomes the relationship between the simplest and the most complex forms when intermediate forms are examined, a very grotesque notion. Habitually, looking at things rather in their statical aspect than in their dynamical aspect, they never realize the fact that, by small increments of modification, any amount of modification may in time be generated.

If I were to be totally sincere, I would say that I do not know why I live and why I do not stop living. The answer probably lies in the irrational character of life which maintains itself without reason.

Because the book became a freak 'bestseller', because I found myself bracketed with the 'Angry Young Men' of the period, I found myself carried to 'fame' on a wave of publicity -- only to discover that this kind of fame is one of the subtlest forms of obscurity. Everybody knew who I was, and nobody knew what I stood for. The public image meant that nobody was interested in what I had to say, for everyone was convinced that they already knew. I could talk until I was blue in the face about my attempt to revise the pessimistic existentialism of Heidegger, Camus and Sartre; as far as most people were concerned, I was an autodidact who was angry about something or other.

One of the many effects of television on radio has been to shift radio from an entertainment medium into a kind of nervous information system.

There is no man so good, who, were he to submit all his thoughts and actions to the laws, would not deserve hanging ten times in his life.

Crime is naught but misdirected energy. So long as every institution of today, economic, political, social, and moral, conspires to misdirect human energy into wrong channels; so long as most people are out of place doing the things they hate to do, living a life they loathe to live, crime will be inevitable, and all the laws on the statutes can only increase, but never do away with, crime.

No one has yet been found so firm of mind and purpose as resolutely to compel himself to sweep away all theories and common notions, and to apply the understanding, thus made fair and even, to a fresh examination of particulars. Thus it happens that human knowledge, as we have it, is a mere medley and ill-digested mass, made up of much credulity and much accident, and also of the childish notions which we at first imbibed.

In this sense Marxism performs the function of a religion, and its efficacy is of a religious character. But it is a caricature and a bogus form of religion, since it presents its temporal eschatology as a scientific system, which religious mythologies do not purport to be.

Tell him to live by yes and no - yes to everything good, no to everything bad.

That man and woman have an equality of duties and rights is accepted by woman even less than by man. Behind his destiny woman must annihilate herself, must be only his complement. A woman dedicates herself to the vocation of her husband; she fills up and performs the subordinate parts in it. But if she has any destiny, any vocation of her own, she must renounce it, in nine cases out of ten.

The cult of the Virgin, Mariolatry, which by the gradual elevation of the divine element in the Virgin has led almost to her deification, answers merely to the feeling that God should be a perfect man, that God should include in his nature the feminine element. The progressive exaltation of the Virgin Mary, the work of Catholic piety, having its beginning in the expression Mother of God, ...has culminated in attributing to her the status of co-redeemer and in the dogmatic declaration of her conception without the stain of original sin. Hence she now occupies a position between Humanity and Divinity and nearer Divinity than Humanity. And it has been surmised that in course of time she may perhaps even come to be regarded as yet another personal manifestation of the Godhead.

Beauty is a pledge of the possible conformity between the soul and nature, and consequently a ground of faith in the supremacy of the good.

There ought to be system of manners in every nation which a well-formed mind would be disposed to relish. To make us love our country, our country ought to be lovely.

We are interested in others, when they are interested in us.

As long as politics is the shadow cast on society by big business, the attenuation of the shadow will not change the substance.

What I had to say was so clear and I felt it so deeply that I am amazed by the tediousness, repetitiousness, verbiage, and disorder of this writing. What would have made it lively and vehement coming from another's pen is precisely what has made it dull and slack coming from mine. The subject was myself, and I no longer found on my own interest that zeal and vigor of courage which can exalt a generous soul only for another person's cause.

The truth is, that the greatest enemies of the doctrine of Jesus are those, calling themselves the expositors of them, who have perverted them to the structure of a system of fancy absolutely incomprehensible, and without any foundation in his genuine words. And the day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin will be classed with the fable of the generation of Minerva in the brain of Jupiter ... But may we hope that the dawn of reason and freedom of thought in these United States will do away with this artificial scaffolding, and restore to us the primitive and genuine doctrines of this most venerated reformer of human errors.

The commonest and cheapest sounds, as the barking of a dog, produce the same effect on fresh and healthy ears that the rarest music does. It depends on your appetite for sound. Just as a crust is sweeter to a healthy appetite than confectionery to a pampered or diseased one.

Just as a vagrant accused of stealing a carrot from a field stands before a comfortably seated judge who keeps up an elegant flow of queries, comments and witticisms while the accused is unable to stammer a word, so truth stands before an intelligence which is concerned with the elegant manipulation of opinions.

In man (as the only rational creature on earth) those natural capacities which are directed to the use of his reason are to be fully developed only in the race, not in the individual.

It is the simple hypotheses of which one must be most wary; because these are the ones that have the most chances of passing unnoticed.

The critique of the highest values hitherto does not simply refute them or declare them invalid. It is rather a matter of displaying their origins as impositions which must affirm precisely what ought to be negated by the values established.

What is beginning to emerge, then, is a theory about psychic sensitivity. It runs as follows. When I relax deeply, it is as if someone opened up the partition between the two compartments of my brain, turning them into a single large room. I experience a sense of mental freedom as if I can suddenly breathe more deeply, and a feeling of contact with things. Everyone has had the experience of being in a state of hurry or excitement, and failing to notice that they have bruised or scratched themselves -- until the excitement evaporates and the pain makes itself known. Hurry and tension raise our sensitivity threshold, and at the same time, erect a glass wall between us and reality. In the "unicameral" state, this wall vanishes, and everything seems more real.

Just as it sometimes happens that deformed offspring are produced by deformed parents, and sometimes not, so the offspring produced by a female are sometimes female, sometimes not, but male, because the female is as it were a deformed male.

Will is to grace as the horse is to the rider.

The greatest problem for the human race, to the solution of which Nature drives man, is the achievement of a universal civic society which administers law among men.

The good life, as I conceive it, is a happy life. I do not mean that if you are good you will be happy; I mean that if you are happy you will be good.

First, the physicists in the persons of Faraday and Maxwell, proposed the "electromagnetic field" in contradistinction to matter, as a reality of a different category. Then, during the last century, the mathematicians, ... secretly undermined belief in the evidence of Euclidean Geometry. And now, in our time, there has been unloosed a cataclysm which has swept away space, time, and matter hitherto regarded as the firmest pillars of natural science, but only to make place for a view of things of wider scope and entailing a deeper vision. This revolution was promoted essentially by the thought of one man, Albert Einstein.

Man is to be found in reason, God in the passions.

By reducing any quality to quantity, myth economizes intelligence: it understands reality more cheaply.

We collect individuals into 'kinds' by applying to them the Idea of Likeness.
