The purpose of aphorisms is to keep fools who have memorised them from having nothing to say.

The doors of heaven and hell are adjacent and identical.

If you want to do evil, science provides the most powerful weapons to do evil; but equally, if you want to do good, science puts into your hands the most powerful tools to do so. The trick is to want the right things, then science will provide you with the most effective methods of achieving them.

It is crazy to want what is impossible. And impossible for the wicked not to do so.

There is something in the nature of tea that leads us into a world of quiet contemplation of life.

I shall need only myself to be happy.

Men who prefer any load of infamy, however great, to any pressure of taxation, however light.

Why dost thou not retire like a guest sated with the banquet of life, and with calm mind embrace, thou fool, a rest that knows no care?

No matter what anyone says or does, my task is to be good.

Those who devote themselves to rituals must ignore themselves. Rituals produce a distance from the self, a self-transcendence.

There is a strong affinity between the forces of empire and a politics of hate that justifies policies of domination and exclusion. So long as people's attention is focused on fear and hatred of foreigners or members of a particular religious group, such as Muslims, they are distracted from organizing to deal with the system of institutional domination and exploitation that is the real source of their insecurity.

Two conflicting types of educational systems spring from these conflicting aims. One is public and common to many, the other private and domestic. If you wish to know what is meant by public education, read Plato's Republic. Those who merely judge books by their titles take this for a treatise on politics, but it is the finest treatise on education ever written. In popular estimation the Platonic Institute stands for all that is fanciful and unreal. For my own part I should have thought the system of Lycurgus far more impracticable had he merely committed it to writing. Plato only sought to purge man's heart; Lycurgus turned it from its natural course. The public institute does not and cannot exist, for there is neither country nor patriot. The very words should be struck out of our language. The reason does not concern us at present, so that though I know it I refrain from stating it.

The more one has suffered, the less one demands. To protest is a sign one has traversed no hell.

The appreciation of the merits of art (of the emotions it conveys) depends upon an understanding of the meaning of life, what is seen as good and evil. Good and evil are defined by religions.

If a man has no humaneness what can his propriety be like? If a man has no humaneness what can his happiness be like?

For want of the apparatus of propositional functions, many logicians have been driven to the conclusion that there are unreal objects. It is argued, e.g., by Meinong, that we can speak about "the golden mountain," "the round square," and so on; we can make true propositions of which these are the subjects; hence they must have some kind of logical being, since otherwise the propositions in which they occur would be meaningless. In such theories, it seems to me, there is a failure of that feeling for reality which ought to be preserved even in the most abstract studies. Logic, I should maintain, must no more admit a unicorn than zoology can; for logic is concerned with the real world just as truly as zoology, though with its more abstract and general features.

True and perfect Friendship is, to make one heart and mind of many hearts and bodies.

All the problems that disturb us today-the cutting down of forests and the erosion of the soil; the emancipation of woman and the limitation of the family; the conservatism of the established, and the experimentalism of the unplaced, in morals, music, and government; the corruptions of politics and the perversions of conduct; the conflict of religion and science, and the weakening of the supernatural supports of morality; the war of the classes, the nations, and the continents; the revolutions of the poor against the economically powerful rich, and of the rich against the politically powerful poor; the struggle between democracy and dictatorship, between individualism and communism, between the East and the West-all these agitated, as if for our instruction, the brilliant and turbulent life of ancient Hellas. There is nothing in Greek civilization that does not illuminate our own.

During his lifetime Gurdjieff did not publish any books on the techniques of his teaching, and his pupils were bound to secrecy on the subject. Since his death in Paris in 1949, however, many of his works have been published, and there has been a flood of memoirs by disciples and admirers. Gurdjieff was in almost ever respect the antithesis of Aleister Crowley. Whereas Crowley craved publicity, Gurdjieff shunned it. Crowley was forgotten for two decades after his death; Gurdjieff on the contrary, has become steadily better known, and his influence continues to grow. One of the main reasons for this is that there was so little of the charlatan about him. He is no cult figure with hordes of gullible disciples. What he has to teach makes an appeal to the intelligence, and can be fully understood only by those who are prepared to make a serious effort.

Nationality is not the only kind of social membership, nor is it an exclusive tie. However, it is the only form of membership that has so far shown itself able to sustain a democratic process and a liberal rule of law.

Man is an imagining being.

No natural boundary seems to be set to the efforts of man; and what is not yet done is only what he has not yet attempted to do. Variant: What is not yet done is only what we have not yet attempted to do.

The patient typically finds himself impelled by some deep, inner conviction that something is true, or right, or virtuous: a conviction that doesn't seem to owe anything to evidence or reason, but which, nevertheless, he feels as totally compelling and convincing. We doctors refer to such a belief as "faith".

What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift it out? How much then is a man better than a sheep? Wherefore it is lawful to do well on the sabbath days.

If just once you were depressed for no reason, you have been so all your life without knowing.

As we can not give a general definition of energy, the principle of the conservation of energy signifies simply that there is something which remains constant.

A theory of cultural change is impossible without knowledge of the changing sense ratios effected by various externalizations of our senses.

I learn with great satisfaction that you are about committing to the press the valuable historical and State papers you have been so long collecting. Time and accident are committing daily havoc on the originals deposited in our public offices. The late war has done the work of centuries in this business. The last cannot be recovered, but let us save what remains; not by vaults and locks which fence them from the public eye and use in consigning them to the waste of time, but by such a multiplication of copies, as shall place them beyond the reach of accident.

No place in the world has had a comparable role to that of the nameless mountain or valley where mankind first attained self-consciousness. Let us be proud ... of the old patriarchs who, at the foot of Imaiis, laid the foundations of what we are and of what we shall become.

A son is a mirror in which the father sees himself reflected, and the father is a mirror in which the son sees himself as he will be in the future.

The human understanding is unquiet; it cannot stop or rest, and still presses onward, but in vain. Therefore it is that we cannot conceive of any end or limit to the world, but always as of necessity it occurs to us that there is something beyond... But he is no less an unskilled and shallow philosopher who seeks causes of that which is most general, than he who in things subordinate and subaltern omits to do so.

In the world as we find it, even the barest requirements of a life worth living cannot all be always met in full. Toppling a tyranny may trigger civil war. Protecting a broad range of liberal freedoms may result in the regime that guarantees them being short lived. At the same time, supporting a strong state as a bulwark against anarchy may worsen the abuse of power. Wise policy can temper these conflicts. It cannot hope to overcome them.

Scientists have pushed back the horizon of time from the biblical 6,000 years to 4,600,000,000 years for the age of Earth a 760,000-fold increase.

The professional tends to classify and to specialize, to accept uncritically the ground rules of the environment. The ground rules provided by the mass response of his colleagues serves as a pervasive environment of which he is contentedly unaware.

All is ephemeral - fame and the famous as well.

Just as modern mass production requires the standardization of commodities, so the social process requires standardization of man, and this standardization is called equality.

God might grant us riches, honours, life, and even health, to our own hurt; for every thing that is pleasing to us is not always good for us. If he sends us death, or an increase of sickness, instead of a cure, Vvrga tua et baculus, tuus ipsa me consolata sunt. "Thy rod and thy staff have comforted me," he does it by the rule of his providence, which better and more certainly discerns what is proper for us than we can do; and we ought to take it in good part, as coming from a wise and most friendly hand.

Then take, good sir, your pleasure while you may; With life so short 'twere wrong to lose a day.

There are two kinds of pleasure: one consisting in a state of rest, in which both body and mind are undisturbed by any kind of pain; the other arising from an agreeable agitation of the senses, producing a correspondent emotion in the soul. It is upon the former of these that the enjoyment of life chiefly depends. Happiness may therefore be said to consist in bodily ease, and mental tranquility.

Human beings have a physical need to tell themselves when at work: "Let's have done with it now," and it's having constantly to go on thinking in the face of this need when philosophizing that makes this work so strenuous.

Nothing is so difficult as not deceiving oneself.

If you reject absolutely any single sensation without stopping to discriminate with respect to that which awaits confirmation between matter of opinion and that which is already present, whether in sensation or in feelings or in any immediate perception of the mind, you will throw into confusion even the rest of your sensations by your groundless belief and so you will be rejecting the standard of truth altogether. If in your ideas based upon opinion you hastily affirm as true all that awaits confirmation as well as that which does not, you will not escape error, as you will be maintaining complete ambiguity whenever it is a case of judging between right and wrong opinion.

Situation seems to be the mould in which men's characters are formed.

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.

Custom reconciles us to every thing.

Time is the wisest of all things that are; for it brings everything to light.

In tetrad form, the artefact is seen to be not netural or passive, but an active logos or utterance of the human mind or body that transforms the user and his ground.
