There is room in the world, no doubt, and even in old countries, for a great increase of population, supposing the arts of life to go on improving, and capital to increase. But even if innocuous, I confess I see very little reason for desiring it. The density of population necessary to enable mankind to obtain, in the greatest degree, all the advantages both of co-operation and of social intercourse, has, in all the most populous countries, been attained. If the earth must lose that great portion of its pleasantness which it owes to things that the unlimited increase of wealth and population would extirpate from it, for the mere purpose of enabling it to support a larger but not a better or a happier population, I sincerely hope, for the sake of posterity, that they will be content to be stationary, long before necessity compels them to it..

I have endeavoured to show that no absolute structural line of demarcation, wider than that between the animals which immediately succeed us in the scale, can be drawn between the animal world and ourselves; and I may add the expression of my belief that the attempt to draw a physical distinction is equally futile, and that even the highest faculties of feeling and of intellect begin to germinate in lower forms of life.

You can never plan the future by the past.

Believe me, my friends, you are yet very deficient with regard to the best modes of training your children, or of arranging your domestic concerns.

"Normal science" means research firmly based upon one or more past scientific achievements, achievements that some particular scientific community acknowledges for a time as supplying the foundation for its further practice.

With so many mind-bytes to be downloaded, so many mental codons to be replicated, it is no wonder that child brains are gullible, open to almost any suggestion, vulnerable to subversion, easy prey to Moonies, Scientologists and nuns. Like immune-deficient patients, children are wide open to mental infections that adults might brush off without effort.

Although our case is different from that of ascetics who remove themselves from the world, the situation of the latest technological civilization might offer the incentive for commitments of this kind. In a large city, in mass society, among the almost unreal swarming of faceless beings, an essential sense of isolation or of detachment often occurs naturally, perhaps even more than in the solitude of moors and mountains.

Straightforward preaching spoils the effectiveness of a story. If you can't resist the impulse to improve your fellow human beings, do it subtly.

Bad company is as instructive as licentiousness. One makes up for the loss of one's innocence with the loss of one's prejudices.

So the majority of the highest classes of that age, even the popes and ecclesiastics, really believed in nothing at all. They did not believe in the Church doctrine, for they saw its insolvency; but neither could they follow Francis of Assisi, Kelchitsky, and most of the sectarians in acknowledging the moral, social teaching of Christ, for that undermined their social position. And so these people remained without any religious view of life. And, having none, they could have no standard with which to estimate what was good and what was bad art, but that of personal enjoyment.

If it is pleasing to observe in nature her desire to paint God in all his works, in which we see some traces of him because they are his images, how much more just is it to consider in the productions of minds the efforts which they make to imitate the essential truth, even in shunning it, and to remark wherein they attain it and wherein they wander from it, as I have endeavored to do in this study.

The years as they pass plunder us of one thing after another.

A sensible human once said, "If people knew how much ill-feeling unselfishness occasions, it would not be so often recommended from the pulpit"; and again, "She's the sort of woman who lives for others-you can always tell the others by their hunted expression."

There is another ground of hope that must not be omitted. Let men but think over their infinite expenditure of understanding, time, and means on matters and pursuits of far less use and value; whereof, if but a small part were directed to sound and solid studies, there is no difficulty that might not be overcome.

This is the Outsider's extremity. He does not prefer not to believe; he doesn't like feeling that futility gets the last word in the universe; his human nature would like to find something it can answer to with complete assent. But honesty prevents his accepting a solution that he cannot reason about.

The pursuit of individual happiness within those limits prescribed by social conditions, is the first requisite to the attainment of the greatest general happiness.

Language does for intelligence what the wheel does for the feet and the body. It enables them to move from thing to thing with greater ease and speed and ever less involvement.

Technical progress and more comfortable living permit the systematic inclusion of libidinal components into the realm of commodity production and exchange. But no matter how controlled the mobilization of instinctual energy may be (it sometimes amounts to a scientific management of libido), no matter how much it may serve as a prop for the status quo-it is also gratifying to the managed individuals, just as racing the outboard motor, pushing the power lawn mower, and speeding the automobile are fun.

The law will never make men free; it is men who have got to make the law free.

...to the question whether or not the motion of the Earth in space can be made perceptible in terrestrial experiments. We have already remarked... that all attempts of this nature led to a negative result. Before the theory of relativity was put forward, it was difficult to become reconciled to this negative result.

Someone once asked me, "If you had your choice, Dr. Asimov, would it be women or writing?" My answer was, "Well, I can write for twelve hours at a time without getting tired."

The idea of creating a national bank I do not concur in, because it seems now decided that Congress has not that power (although I sincerely wish they had it exclusively), and because I think there is already a vast redundancy rather than a scarcity of paper medium.

I never lose an opportunity of urging a practical beginning, however small, for it is wonderful how often in such matters the mustard-seed germinates and roots itself.

The initial revelation of any monastery: everything is nothing. Thus begin all mysticisms. It is less than one step from nothing to God, for God is the positive expression of nothingness.

Marx explains the alienation of labor as exemplified in, first, the relation of the worker to the product of his labor and, second, the relation of the worker to his own activity. P. 276

Let the modern eye look earnestly on that old midnight hour in St. Edmundsbury Church, shining yet on us, ruddy-bright, through the depths of seven hundred years; and consider mournfully what our Hero-worship once was, and what it now is!

One cannot reduce terror by holding over the world the threat of what it most fears.

Let great authors have their due, as time, which is the author of authors, be not deprived of his due, which is, further and further to discover truth.

Haven't people learned yet that the time of superficial intellectual games is over, that agony is infinitely more important than syllogism, that a cry of despair is more revealing than the most subtle thought, and that tears always have deeper roots than smiles?

And if the immortality of the soul had been unable to find vindication in rational empiricism, neither is it satisfied with pantheism. To say that everything is God, and that when we die, we return to God, or more accurately, continue in Him, avails our longing nothing; for if this indeed be so, then we were in God before we were born, and if we die we return to where we were before being born, then the human soul, the individual consciousness, is perishable. And since we know very well that God, the personal and conscious God of Christian monotheism, is simply the provider, and above all the guarantor, of our immortality, pantheism is said, and rightly said to be merely atheism disguised; and in my opinion, undisguised.

...nothing is stronger than true reality.

But now persecution is good, because it exists; every law which originated in ignorance and malice, and gratifies the passions from whence it sprang, we call the wisdom of our ancestors: when such laws are repealed, they will be cruelty and madness; till they are repealed, they are policy and caution.

I would rather sleep in the southern corner of a little country churchyard, than in the tombs of the Capulets.

Any plea ... for institutionalized risk-assessment, beefed-up bioethics panels, academic review bodies, worse-case scenario planning, more intensive computer simulations, systematic long-term planning and the institutionalized study of existential risks is admirable. But so is urgent action to combat the global pandemic of suffering. "The easiest pain to bear is someone else's"

In the presence of the total reality upon which our conduct is founded, our knowledge is characterized by peculiar limitations and aberrations. We cannot say in principle that "error is life and knowledge is death," because a being involved in persistent errors would continually act wide of the purpose, and would thus inevitably perish.

The notion that one can discover large patterns or regularities in the procession of historical events is naturally attractive to those who are impressed by the success of the natural sciences in classifying, correlating, and above all predicting.

The sneaking arts of underling tradesmen are thus erected into political maxims for the conduct of a great empire; for it is the most underling tradesmen only who make it a rule to employ chiefly their own customers. A great trader purchases his good always where they are cheapest and best, without regard to any little interest of this kind.

The less somebody knows and understands himself the less great he is, however great may be his talent. For this reason our scientists are not great.

The fact that life evolved out of nearly nothing, some 10 billion years after the universe evolved out of literally nothing, is a fact so staggering that I would be mad to attempt words to do it justice.

It may be observed, that provinces amid the vicissitudes to which they are subject, pass from order into confusion, and afterward recur to a state of order again; for the nature of mundane affairs not allowing them to continue in an even course, when they have arrived at their greatest perfection, they soon begin to decline. In the same manner, having been reduced by disorder, and sunk to their utmost state of depression, unable to descend lower, they, of necessity, reascend; and thus from good they gradually decline to evil, and from evil again return to good. The reason is, that valor produces peace; peace, repose; repose, disorder; disorder, ruin; so from disorder order springs; from order virtue, and from this, glory and good fortune.

We know in bodies only matter, and we observe the faculty of feeling only in bodies: on what foundation then can we erect an ideal being, disowned by all our knowledge?

And I will tell you something else: there is no birth of all mortal things, nor any end in wretched death, but only a mixing and dissolution of mixtures; 'birth' is so called on the part of mankind.

The object of walking is to relax the mind. You should therefore not permit yourself even to think while you walk; but divert your attention by the objects surrounding you. Walking is the best possible exercise. Habituate yourself to walk very far. The Europeans value themselves on having subdued the horse to the uses of man; but I doubt whether we have not lost more than we have gained, by the use of this animal. No one has occasioned so much, the degeneracy of the human body. An Indian goes on foot nearly as far in a day, for a long journey, as an enfeebled white does on his horse; and he will tire the best horses. There is no habit you will value so much as that of walking far without fatigue.

Speak straight and clear! I only hear that manly prayerwhich like a huge fist breaks my head against the stones.

Repentance for one's evil deeds is the safeguard of life.

Cultural dominance by either the left or the right hemisphere is largely dependent upon environmental factors.

Well, what does "good" mean anyway...? As Wittgenstein suggested, "good," like "game," has a family of meanings. Prominent among them is this one: "meets the criteria or standards of assessment or evaluation."

It is remarkable that, notwithstanding the universal favor with which the New Testament is outwardly received, and even the bigotry with which it is defended, there is no hospitality shown to, there is no appreciation of, the order of truth with which it deals.

Most men would feel insulted, if it were proposed to employ them in throwing stones over a wall, and then in throwing them back, merely that they might earn their wages. But many are no more worthily employed now.

Self-respect is the cornerstone of all virtue.
