Every philosophical problem, when it is subjected to the necessary analysis and justification, is found either to be not really philosophical at all, or else to be, in the sense in which we are using the word, logical.

In fact the opposition of instinct and reason is mainly illusory. Instinct, intuition, or insight is what first leads to the beliefs which subsequent reason confirms or confutes; but the confirmation, where it is possible, consists, in the last analysis, of agreement with other beliefs no less instinctive. Reason is a harmonising, controlling force rather than a creative one. Even in the most purely logical realms, it is insight that first arrives at what is new.

The true function of logic ... as applied to matters of experience ... is analytic rather than constructive; taken a priori, it shows the possibility of hitherto unsuspected alternatives more often than the impossibility of alternatives which seemed prima facie possible. Thus, while it liberates imagination as to what the world may be, it refuses to legislate as to what the world is.

The conception of the necessary unit of all that is resolves itself into the poverty of the imagination, and a freer logic emancipates us from the straitwaistcoated benevolent institution which idealism palms off as the totality of being.

The best life is the one in which the creative impulses play the largest part and the possessive impulses the smallest.

Without effort and change, human life cannot remain good. It is not a finished Utopia that we ought to desire, but a world where imagination and hope are alive and active.

The facts of science, as they appeared to him [Heraclitus], fed the flame in his soul, and in its light, he saw into the depths of the world.

Mysticism is, in essence, little more than a certain intensity and depth of feeling in regard to what is believed about the universe.

In a logically perfect language, there will be one word and no more for every simple object, and everything that is not simple will be expressed by a combination of words, by a combination derived, of course, from the words for the simple things that enter in, one word for each simple component.

To understand a name you must be acquainted with the particular of which it is a name.

The reason that I call my doctrine logical atomism is because the atoms that I wish to arrive at as the sort of last residue in analysis are logical atoms and not physical atoms. Some of them will be what I call "particulars" - such things as little patches of color or sounds, momentary things - and some of them will be predicates or relations and so on.

My desire and wish is that the things I start with should be so obvious that you wonder why I spend my time stating them. This is what I aim at because the point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.

I do not pretend to start with precise questions. I do not think you can start with anything precise. You have to achieve such precision as you can, as you go along.

The process of philosophizing, to my mind, consists mainly in passing from those obvious, vague, ambiguous things, that we feel quite sure of, to something precise, clear, definite, which by reflection and analysis we find is involved in the vague thing that we start from, and is, so to speak, the real truth of which that vague thing is a sort of shadow.

Philosophy, from the earliest times, has made greater claims, and achieved fewer results, than any other branch of learning.

Philosophy is to be studied, not for the sake of any definite answers to its questions, since no definite answers can, as a rule, be known to be true, but rather for the sake of the questions themselves; because these questions enlarge our conception of what is possible, enrich our intellectual imagination and diminish the dogmatic assurance which closes the mind against speculation; but above all because, through the greatness of the universe which philosophy contemplates, the mind is also rendered great, and becomes capable of that union with the universe which constitutes its highest good.

I don't care for the applause one gets by saying what others are thinking; I want actually to change people's thoughts. Power over people's minds is the main personal desire of my life; and this sort of power is not acquired by saying popular things.

It seems clear to me that marriage ought to be constituted by children, and relations not involving children ought to be ignored by the law and treated as indifferent by public opinion. It is only through children that relations cease to be a purely private matter.

Righteousness cannot be born until self-righteousness is dead.

No nation was ever so virtuous as each believes itself, and none was ever so wicked as each believes the other.

Of all evils of war the greatest is the purely spiritual evil: the hatred, the injustice, the repudiation of truth, the artificial conflict.

It must not be supposed that this conflict is, on the part of the Teuton, aggressive in substance, whatever it may be in form. In substance it is defensive, the attempt to preserve Central Europe for a type of civilisation indubitably higher and of more value to mankind than that of any Slav State. The existence of the Russian menace on the Eastern border is, quite legitimately, a nightmare to Germany.

The Austrians are a highly civilised race, half-surrounded by Slavs in a relatively backward state of culture. ... Servia, a country so barbaric that a man can secure the throne by instigating the assassination of his predecessor, is engaged constantly in fermenting the racial discontent of men of the same race who are Austrian subjects.

Essentially, this war...is a great race-conflict, a conflict of Teuton and Slav, in which certain other nations, England, France and Belgium, have been led into cooperation with the Slav. ... The conflict of Germany and Russia has been produced not by this or that diplomatic incident, but by primitive passions expressing themselves in the temper of the two races.

I don't like the spirit of socialism - I think freedom is the basis of everything.

[One] must look into hell before one has any right to speak of heaven.

Philosophy, if it cannot answer so many questions as we could wish, has at least the power of asking questions which increase the interest of the world, and show the strangeness and wonder lying just below the surface even in the commonest things of daily life.

Is there any knowledge in the world which is so certain that no reasonable man could doubt it?

No man is liberated from fear who dare not see his place in the world as it is; no man can achieve the greatness of which he is capable until he has allowed himself to see his own littleness.

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded. They divide their time between labour designed to postpone the moment of dissolution for themselves and frantic struggles to hasten it for others of their kind.

What a queer work the Bible is. ...Some texts are very funny. Deut. XXIV, 5: "When a man hath taken a new wife, he shall not go out to war, neither shall he be charged with any business: but he shall be free at home one year, and shall cheer up his wife which he hath taken." I should never have guessed "cheer up" was a Biblical expression. Here is another really inspiring text: "Cursed be he that lieth with his mother-in-law. And all the people shall say, Amen." St Paul on marriage: "I say therefore to the unmarried and widows, It is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn." This has remained the doctrine of the Church to this day. It is clear that the Divine purpose in the text "it is better to marry than to burn" is to make us all feel how very dreadful the torments of Hell must be.

The principal source of the harm done by the State is the fact that power is its chief end.

How much good it would do if one could exterminate the human race.

I hate the world and almost all the people in it. I hate the Labour Congress and the journalists who send men to be slaughtered, and the fathers who feel a smug pride when their sons are killed, and even the pacifists who keep saying human nature is essentially good, in spite of all the daily proofs to the contrary. I hate the planet and the human race - I am ashamed to belong to such a species.

I do wish I believed in the life eternal, for it makes me quite miserable to think man is merely a kind of machine endowed, unhappily for himself, with consciousness.
