I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.

The inclination to seek the truth is safer than the presumption which regards unknown things as known.

Amid a multitude of projects, no plan is devised.

Seek after the good, and with much toil shall ye find it; the evil turns up of itself without your seeking it.

In the first place, the German is a branch of the Teutonic race. Of the latter it is sufficient to say here that its mission was to combine the social order established in ancient Europe with the true religion preserved in ancient Asia, and in this way to develop in and by itself a new and different age after the ancient world had perished.

It seems hard for the American people to believe that anything could be more exciting than the times themselves. What we read daily and view on the TV has thrust imagined forms into the shadow. We are staggeringly rich in facts, in things, and perhaps, like the nouveau riche of other ages, we want our wealth faithfully reproduced by the artist.

If science is not to degenerate into a medley of ad hoc hypotheses, it must become philosophical and must enter upon a thorough criticism of its own foundations.

Can a man who's warm understand one who's freezing?

Among animals, some learn to speak and sing; they remember tunes, and strike the notes as exactly as a musician. Others, for instance the ape, show more intelligence... would it be absolutely impossible to teach the ape a language? I do not think so.

Moreover, there is a victory and defeat, the first and best of victories, the lowest and worst of defeat, which each man gains or sustains at the hands, not of another, but of himself; this shows that there is a war against ourselves going on within every one of us. Book I Sometimes paraphrased as "The first and best victory is to conquer self".

What is left when honor is lost?

The activity of to-day and the assurance of to-morrow.

I deny that anyone knows, or can know, the nature of the two sexes, as long as they have only been seen in their present relation to one another. If men had ever been found in society without women, or women without men, or if there had been a society of men and women in which the women were not under the control of the men, something might have been positively known about the mental and moral differences which may be inherent in the nature of each. What is now called the nature of women is an eminently artificial thing - the result of forced repression in some directions, unnatural stimulation in others.

Do not know the truth by the men, but know the truth, and then you will know who are truthful.

I know that my unity with all people cannot be destroyed by national boundaries and government orders.

Three in the morning. I realize this second, then this one, then the next: I draw up the balance sheet for each minute. And why all this? Because I was born. It is a special type of sleeplessness that produces the indictment of birth.

Utopia is a meta-utopia: the environment in which Utopian experiments may be tried out; the environment in which people are free to do their own thing; the environment which must, to a great extent, be realized first if more particular Utopian visions are to be realized stably.

And as to you, Sir, treacherous in private friendship (for so you have been to me, and that in the day of danger) and a hypocrite in public life, the world will be puzzled to decide whether you are an apostate or an impostor; whether you have abandoned good principles, or whether you ever had any. 

Trying to define yourself is like trying to bite your own teeth.

You get tragedy where the tree, instead of bending, breaks.

The source of our actions resides in an unconscious propensity to regard ourselves as the center, the cause, and the conclusion of time. Our reflexes and our pride transform into a planet the parcel of flesh and consciousness we are. If we had the right sense of our position in the world, if to compare were inseparable from to live, the revelation of our infinitesimal presence would crush us. But to live is to blind ourselves to our own dimensions. . . .

In death too, there is always something of the rich cat that lets the mouse run before devouring it.

We tend to believe the premises because we can see that their consequences are true, instead of believing the consequences because we know the premises to be true. But the inferring of premises from consequences is the essence of induction; thus the method in investigating the principles of mathematics is really an inductive method, and is substantially the same as the method of discovering general laws in any other science.

If man's love for himself be necessary, then his love for Him through whom, first his coming-to-be, and second, his continuance in his essential being with all his inward and outward traits, his substance and his accidents, occur must also be necessary. Whoever is so besotted by his fleshy appetites as to lack this love neglects his Lord and Creator. He possesses no authentic knowledge of Him; his gaze is limited to his cravings and to things of sense. 

To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection.

Character is higher than intellect...A great soul will be strong to live, as well as strong to think.

Poetry and the arts can't exist in America. Mere exposure to the arts does nothing for a mentality which is incorrigibly dialectical. The vital tensions and nutritive action of ideogram remain inaccessible to this state of mind.

A great deal of intelligence can be invested in ignorance when the need for illusion is deep. 

...and if you are common, you can dress up as a woman, show you behind or write poems: there's nothing offensive about a naked behind if it's everybody's; each person will be mirrored in it.

But the Jews are so hardened that they listen to nothing; though overcome by testimonies they yield not an inch. It is a pernicious race, oppressing all men by their usury and rapine. If they give a prince or magistrate a thousand florins, they extort twenty thousand from the subjects in payment. We must ever keep on guard against them.

I fancy that most people who think at all have done a great deal of their thinking in the first fourteen years.

Labor is a commodity, like any other, and its price is therefore determined by exactly the same laws that apply to other commodities. In a regime of big industry or of free competition - as we shall see, the two come to the same thing - the price of a commodity is, on the average, always equal to its cost of production. Hence, the price of labor is also equal to the cost of production of labor. But, the costs of production of labor consist of precisely the quantity of means of subsistence necessary to enable the worker to continue working, and to prevent the working class from dying out. The worker will therefore get no more for his labor than is necessary for this purpose; the price of labor, or the wage, will, in other words, be the lowest, the minimum, required for the maintenance of life.

No man who has once heartily and wholly laughed can be altogether irreclaimably bad.

Conformity to nature has no connection whatever with right and wrong. The idea can never be fitly introduced into ethical discussions at all, except, occasionally and partially, into the question of degrees of culpability. To illustrate this point, let us consider the phrase by which the greatest intensity of condemnatory feeling is conveyed in connection with the idea of nature - the word "unnatural." That a thing is unnatural, in any precise meaning which can be attached to the word, is no argument for its being blamable; since the most criminal actions are to a being like man not more unnatural than most of the virtues.

As man loses touch with his 'inner being', his instinctive depths, he finds himself trapped in the world of consciousness, that is to say, in the world of other people. Any poet knows this truth; when other people sicken him, he turns to hidden resources of power inside himself, and he knows then that other people don't matter a damn. He knows the 'secret life' inside him is the reality; other people are mere shadows in comparison. but the 'shadows' themselves cling to one another. 'Man is a political animal', said Aristotle, telling one of the greatest lies in human history. Man has more in common with the hills, or with the stars, than with other men.

If one assumes, as I do, that battery is caused by the belief permeating this culture that hierarchical rule and coercive authority are natural, then all our relationships tend to be based on power and domination, and thus all forms of battery are linked.

The manufacturing worker almost always lives in the countryside and in a more or less patriarchal relation to his landlord or employer; the proletarian lives, for the most part, in the city and his relation to his employer is purely a cash relation. The manufacturing worker is torn out of his patriarchal relation by big industry, loses whatever property he still has, and in this way becomes a proletarian.

What is called an acute knowledge of human nature is mostly nothing but the observer's own weaknesses reflected back from others.

The pivot round which the religious life... revolves, is the interest of the individual in his private personal destiny. Religion, in short, is a monumental chapter in the history of human egotism. The gods believed in-whether by crude savages or by men disciplined intellectually-agree with each other in recognizing personal calls. Religious thought is carried on in terms of personality, this being, in the world of religion, the one fundamental fact. To-day, quite as much as at any previous age, the religious individual tells you that the divine meets him on the basis of his personal concerns.

What could be a better indication of man's continued dependence on nature than the fact that today's so-called post-industrial societies satisfy most of their food needs through imports from so-called underdeveloped countries?

Volumes might be written upon the impiety of the pious.

Is not every true Reformer, by the nature of him, a Priest first of all? He appeals to Heaven's invisible justice against Earth's visible force; knows that it, the invisible, is strong and alone strong. He is a believer in the divine truth of things; a seer, seeing through the shows of things; a worshipper, in one way or the other, of the divine truth of things; a Priest, that is. If he be not first a Priest, he will never be good for much as a Reformer.

The violence and injustice of the rulers of mankind is an ancient evil, for which, I am afraid, the nature of human affairs can scarce admit a remedy.

The Divine light is always in man, presenting itself to the senses and to the comprehension, but man rejects it.
