It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living. It is clear also that thought is not free if all the arguments on one side of a controversy are perpetually presented as attractively as possible, while the arguments on the other side can only be discovered by diligent search.

That which has no existence cannot be destroyed - that which cannot be destroyed cannot require anything to preserve it from destruction. Natural rights is simple nonsense: natural and imprescriptible rights, rhetorical nonsense - nonsense upon stilts. But this rhetorical nonsense ends in the old strain of mischievous nonsense for immediately a list of these pretended natural rights is given, and those are so expressed as to present to view legal rights. And of these rights, whatever they are, there is not, it seems, any one of which any government can, upon any occasion whatever, abrogate the smallest particle. The often-quoted phrase 'nonsense upon stilts' is often modernised to 'nonsense on stilts'.

Happiness is the free play of the instincts, and so is youth.

How much pain have cost us the evils which have never happened.

For me any of the little gestures I make are all tentative probes. That's why I feel free to make them sound as outrageous or extreme as possible. Until you make it extreme, the probe is not very efficient.

How can great minds be produced in a country where the test of a great mind is agreeing in the opinions of small minds?

Nature, therefore, is subject with absolute precision to all the precepts of geometry as to all the properties of space there demonstrated, this being the subjective condition, not hypothetically but intuitively given, of every phenomenon in which nature can ever be revealed to the senses.

Phenomenology is not a philosophy; it is a philosophical method, a tool. It is like an adjustable spanner that can be used for dismantling a refrigerator or a car, or used for hammering in nails, or even for knocking somebody out.

Happiness is not achieved by the conscious pursuit of happiness; it is generally the by-product of other activities.

And of universal nature, the notion I would offer, should be something like this. Nature is the aggregate of the bodies, that make up the world, in its present state, considered as a principle, by virtue whereof, they act and suffer, according to the laws of motion, prescribed by the author of things.

Nothing in this book is true.

To be old is a glorious thing when one has not unlearned what it means to begin, this old man had perhaps first learned it thoroughly in old age.

You know I am not born to tread in the beaten track - the peculiar bent of my nature pushes me on.

A thing, moderately good, is not so good as it ought to be. Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.

The wine is bottled poetry.

We have convictions only if we have studied nothing thoroughly.

As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprise, and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body, and stamp no character on the mind. Let your gun therefore be the constant companion of your walks. Never think of taking a book with you.

Man is an imagining being.

Cease therefore to be dismayed by the mere novelty and so to reject reason from your mind with loathing: weigh the questions rather with keen judgment and if they seem to you to be true, surrender, or if the thing is false, gird yourself to the encounter.

Tell me to what you pay attention and I will tell you who you are.

Both are torn halves of an integral freedom, to which however they do not add up.

Science is a systematic method for studying and working out those generalizations that seem to describe the behavior of the universe. It could exist as a purely intellectual game that would never affect the practical life of human beings either for good or evil, and that was very nearly the case in ancient Greece, for instance. Technology is the application of scientific findings to the tools of everyday life, and that application can be wise or unwise, useful or harmful. Very often, those who govern technological decisions are not scientists and know little about science.

I shall take leave to think the worse, rather of the practice of the men than of the book of God.

Identical in the physical processes by which he originates-identical in the early stages of his formation-identical in the mode of his nutrition before and after birth, with the animals which lie immediately below him in the scale-Man, if his adult and perfect structure be compared with theirs, exhibits, as might be expected, a marvellous likeness of organization. He resembles them as they resemble one another-he differs from them as they differ from one another.-And, though these differences and resemblances cannot be weighed and measured, their value may be readily estimated; the scale or standard of judgment, touching that value, being afforded and expressed by the system of classification of animals now current among zoologists.

If we are not stupid or insincere when we say that the good or ill of man lies within his own will, and that all beside is nothing to us, why are we still troubled?

In its solitariness the spirit asks, What, in the way of value, is the attainment of life? And it can find no such value till it has merged its individual claim with that of the objective universe.

Being summoned by the Athenians out of Sicily to plead for his life, Alcibiades absconded, saying that that criminal was a fool who studied a defence when he might fly for it.

Schizophrenia is like love: there is no specifically schizophrenic phenomenon or entity; schizophrenia is the universe of productive and reproductive desiring machines, universal primary production as "the essential reality of man and nature".

He [God] lends us a little of His reasoning powers and that is how we think: He puts a little of His love into us and that is how we love one another. When you teach a child writing, you hold its hand while it forms the letters: that is, it forms the letters because you are forming them. We love and reason because God loves and reasons and holds our hand while we do it.

Acquire the contemplative way of seeing how all things change into one another, and constantly attend to it, and exercise thyself about this part [of philosophy]. For nothing is so much adapted to produce magnanimity. ...But as to what any man shall say or think about him, or do against him, he never even thinks of it, being himself contented with these two things: with acting justly in what he now does, and being satisfied with what is now assigned to him; and he lays aside all distracting and busy pursuits, and desires nothing else than to accomplish the straight course through the law, and by accomplishing the straight course to follow God.

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.

"I am like a broken puppet whose eyes have fallen inside." This remark of a mental patient weighs more heavily than a whole stack of works on introspection.

It is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.

Among civilized and thriving nations, on the contrary, though a great number of people do no labor at all, many of whom consume the produce of ten times, frequently of a hundred times more labour than the greater part of those who work; yet the produce of the whole labour of the society is so great, that all are often abundantly supplied, and a workman, even of the lowest and poorest order, if he is frugal and industrious, may enjoy a greater share of the necessaries and conveniencies of life than it is possible for any savage to acquire.

A logical theory may be tested by its capacity for dealing with puzzles, and it is a wholesome plan, in thinking about logic, to stock the mind with as many puzzles as possible, since these serve much the same purpose as is served by experiments in physical science.

The dynamic principle of fantasy is play, a characteristic also of the child, and as such it appears inconsistent with the principle of serious work. But without this playing with fantasy no creative work has ever yet come to birth. The debt we owe to the play of imagination is incalculable. It is therefore short-sighted to treat fantasy, on account of its risky or unacceptable nature, as a thing of little worth.

The more you obey your conscience, the more your conscience will demand of you.

Thus far, gentlemen, I have been insisting very strenuously upon what the most vulgar common sense has every disposition to assent to and only ingenious philosophers have been able to deceive themselves about. But now I come to a category which only a more refined form of common sense is prepared willingly to allow, the category which of the three is the chief burden of Hegel's song, a category toward which the studies of the new logico-mathematicians, Georg Cantor and the like, are steadily pointing, but to which no modern writer of any stripe, unless it be some obscure student like myself, has ever done anything approaching to justice.

That body is heavier than another which, in an equal bulk, moves downward quicker.

When we leave you and assemble together by ourselves, we talk freely about his sayings and doings, treating them with the respect which they deserve: in your presence deep silence is observed about him, and thus you lose that greatest of pleasures, the hearing the praises of your son, which I doubt not you would be willing to hand down to all future ages, had you the means of so doing, even at the cost of your own life.

A beautiful face is a silent commendation.

Do not yet see, that, if the single man plant himself indomitably on his instincts, and there abide, the huge world will come round to him.

In 1970s Britain, conservative philosophy was the preoccupation of a few half-mad recluses.

Prejudice is of ready application in the emergency; it previously engages the mind in a steady course of wisdom and virtue and does not leave the man hesitating in the moment of decision sceptical, puzzled, and unresolved. Prejudice renders a man's virtue his habit, and not a series of unconnected acts. Through just prejudice, his duty becomes a part of his nature.

The first statement of the two principles reads as follows. First: each person is to have an equal right to the most extensive basic liberty compatible with a similar liberty for others. Second: social and economic inequalities are to be arranged so that they are both (a)reasonably expected to be to everyone's advantage, and (b) attached to positions and offices open to all.

It is said that our paper is as good as silver, because we may have silver for it at the bank where it issues. This is not true. One, two, or three persons might have it; but a general application would soon exhaust their vaults, and leave a ruinous proportion of their paper in its intrinsic worthless form.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.

When the representative body have lost the confidence of their constituents, when they have notoriously made sale of their most valuable rights, when they have assumed to themselves powers which the people never put into their hands, then indeed their continuing in office becomes dangerous to the state, and calls for an exercise of the power of dissolution.
