Every sensible man, every honorable man, must hold the Christian sect in horror.

He who does not give himself leisure to be thirsty cannot take pleasure in drinking.

The use of the intellect in the sciences whose primitive concepts as well as axioms are given by sensuous intuition is only logical, that is, by it we only subordinate cognitions to one another according to their relative universality conformably to the principle of contradiction, phenomena to more general phenomena, and consequences of pure intuition to intuitive axioms. But in pure philosophy, such as metaphysics, in which the use of the intellect in respect to principles is real, that is to say, where the primary concept of things and relations and the very axioms are given originally by the pure intellect itself, and not being intuitions do not enjoy immunity from error, the method precedes the whole science, and whatever is attempted before its precepts are thoroughly discussed and firmly established is looked upon as rashly conceived and to be rejected among vain instances of mental playfulness.

Were a stranger to drop on a sudden into this world, I would show him, as a specimen of its ills, a hospital full of diseases, a prison crowded with malefactors and debtors, a field of battle strewed with carcasses, a fleet foundering in the ocean, a nation languishing under tyranny, famine, or pestilence. To turn the gay side of life to him, and give him a notion of its pleasures; whither should I conduct him? to a ball, to an opera, to court? He might justly think, that I was only showing him a diversity of distress and sorrow.

I am not concerned that I have no place; I am concerned how I may fit myself for one. I am not concerned that I am not known; I seek to be worthy to be known.

Man is a goal-seeking animal. His life only has meaning if he is reaching out and striving for goals.

For the history of the centuries that have passed since the birth of Christ nowhere reveals conditions like those of the present. There has never been such building and planting in the world. There has never been such gluttonous and varied eating and drinking as now. Wearing apparel has reached its limit in costliness. Who has ever heard of such commerce as now encircles the earth? There have arisen all kinds of art and sculpture, embroidery and engraving, the like of which has not been seen during the whole Christian era. In addition men are so delving into the mysteries of things that today a boy of twenty knows more than twenty doctors formerly knew.

Corpses are more fit to be cast out than dung.

If someone were to expound that godliness is to belong to childhood in the temporal sense and thus dwindle and die with the years as childhood does, is to be a happy frame of mind that cannot be preserved but only recollected; if someone were to expound that repentance as a weakness of old age accompanies the decline of one's powers, when the senses are dulled, when sleep no longer strengthens but increases lethargy-this would be ungodliness and foolishness.

But if one should guide his life by true principles, man's greatest riches is to live on a little with contented mind; for a little is never lacking.

Reason is the greatest enemy that faith has: it never comes to the aid of spiritual things, but--more frequently than not--struggles against the divine Word, treating with contempt all that emanates from God.

It is written, My house shall be called the house of prayer; but ye have made it a den of thieves. 21:13 (KJV)

He that is not with me is against me: and he that gathereth not with me scattereth. Luke 11:23 (KJV)

Oh providence! Oh nature! Treasure of the poor, resource of the unfortunate. The person who feels, knows your holy laws and trusts them, the person whose heart is at peace and whose body does not suffer, thanks to you is not entirely prey to adversity.

Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use of the book of the world.

Encourage therefore his inquisitiveness all you can, by satisfying his demands, and informing his judgement, as far as it is capable. When his reasons are any way tolerable, let him find the credit and commendation of it, without being laugh'd at for his mistake be gently put into the right; and if he shew a forwardness to be reasoning about things that come in his way, take care, as much as you can, that no body check this inclination in him, or mislead it by captious or fallacious ways of talking with him. For when all is done, this is the highest and most important faculty of our minds, deserves the greatest care and attention in cultivating it: the right improvement, and exercise of our reason being the highest perfection that a man can attain to in his life.

I do not know, my listener, what your crime, your guilt, your sins are, but surely we are all more or less of the guilt of loving only little. Take comfort, then, in these words just as I take comfort in them.

Preference of vice to virtue, a manifest wrong judgment.

It will be easy for us once we receive the ball of yarn from Ariadne (love) and then go through all the mazes of the labyrinth (life) and kill the monster. But how many are there who plunge into life (the labyrinth) without taking that precaution?

It is soft, smooth and shining like intelligence. Its edges seem sharp but do not cut like justice. It hangs down to the ground like humility. When struck, it gives a clear, ringing sound like music. The strains in it are not hidden and add to its beauty like truthfulness.' What imagination! Confucius extolled Jade's virtues this way.

The fellow who eggs you on to avenge yourself will rob you of what you were going to say, as we forgive our debtors. When you have forfeited that, all your sins will be held against you; absolutely nothing is forgiven.

Guide the people by law, subdue them by punishment; they may shun crime, but will be void of shame. Guide them by example, subdue them by courtesy; they will learn shame, and come to be good.

For as children tremble and fear everything in the blind darkness, so we in the light sometimes fear what is no more to be feared than the things that children in the dark hold in terror and imagine will come true. This terror, therefore, and darkness of mind must be dispelled not by the rays of the sun and glittering shafts of daylight, but by the aspect and law of nature.

Unless I am convinced by the testimony of the Scriptures or by clear reason (for I do not trust either in the pope or in councils alone, since it is well known that they have often erred and contradicted themselves), I am bound by the Scriptures I have quoted and my conscience is captive to the Word of God. I cannot and will not recant anything, since it is neither safe nor right to go against conscience. May God help me. Amen.

Great novelists are philosopher novelists, that is, the contrary of thesis-writers.

There are also Idols formed by the intercourse and association of men with each other, which I call Idols of the Market Place, on account of the commerce and consort of men there. For it is by discourse that men associate, and words are imposed according to the apprehension of the vulgar. And therefore the ill and unfit choice of words wonderfully obstructs the understanding. Nor do the definitions or explanations wherewith in some things learned men are wont to guard and defend themselves, by any means set the matter right. But words plainly force and overrule the understanding, and throw all into confusion, and lead men away into numberless empty controversies and idle fancies.

A wise man sees as much as he ought, not as much as he can

A hymn is the praise of God with song; a song is the exultation of the mind dwelling on eternal things, bursting forth in the voice.

No matter how various the subject matter I write on, I was a science-fiction writer first and it is as a science-fiction writer that I want to be identified.

I recognize the necessity of animal experiments with my mind but not with my heart.

Nobody realizes that some people expend tremendous energy merely to be normal.

You must acquire the best knowledge first, and without delay; it is the height of madness to learn what you will later have to unlearn.

Hear, and understand: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man. 15:10-11 (KJV)

Phenomena of the external sense are examined and set forth in physics; those of the internal sense in empirical psychology. Pure mathematics considers space in geometry and time in pure mechanics. To these is to be added a certain concept, intellectual to be sure in itself, but whose becoming actual in the concrete requires the auxiliary notions of time and space in the successive addition and simultaneous juxtaposition of separate units, which is the concept of number treated in arithmetic.

Let us give Nature a chance; she knows her business better than we do.

Since my logic aims to teach and instruct the understanding, not that it may with the slender tendrils of the mind snatch at and lay hold of abstract notions (as the common logic does), but that it may in very truth dissect nature, and discover the virtues and actions of bodies, with their laws as determined in matter; so that this science flows not merely from the nature of the mind, but also from the nature of things.

Psychologists have hitherto failed to realize that imagination is a necessary ingredient of perception itself.

Let us cultivate our garden.

Don't hold yourselves cheap, seeing that the creator of all things and of you estimates your value so high, so dear, that he pours out for you every day the most precious blood of his only-begotten Son.

The obliteration of the evil hath been practised by two means, some kind of redemption or expiation of that which is past, and an inception or account de novo for the time to come. But this part seemeth sacred and religious, and justly; for all good moral philosophy (as was said) is but a handmaid to religion.

There is not a negro from the coast of Africa who does not, in this respect, possess a degree of magnanimity which the soul of his sordid master is too often scarce capable of conceiving. Fortune never exerted more cruelly her empire over mankind, than when she subjected those nations of heroes to the refuse of the jails of Europe, to wretches who possess the virtues neither of the countries which they come from, nor of those which they go to, and whose levity, brutality, and baseness, so justly expose them to the contempt of the vanquished.

Of all the ways whereby children are to be instructed, and their manners formed, the plainest, easiest, and most efficacious, is, to set before their eyes the examples of those things you would have them do, or avoid; which, when they are pointed out to them, in the practice of persons within their knowledge, with some reflections on their beauty and unbecomingness, are of more force to draw or deter their imitation, than any discourses which can be made to them.

There are degrees of justice, Elijah. When the lesser is incompatible with the greater, the lesser must give way.

We make a ladder of our vices, if we trample those same vices underfoot.

The truth is a trap: you can not get it without it getting you; you cannot get the truth by capturing it, only by its capturing you.

Parmenides: If the one is not, nothing is. Then, and we may add, whether the one is or is not, the one and the others in relation to themselves and to each other all in every way are and are not and appear and do not appear.

Music is associated not only with speculation but with morality. When rhythms and modes reach an intellect through the ear, they doubtless affect and reshape that mind according to their particular character.

It is very likely that there are many, many planets carrying life, even intelligent life, throughout the universe, because there are so many stars. By sheer chance, even if those chances are small, a great many life forms and a great many intelligences may exist.
