I am sitting with a philosopher in the garden; he says again and again "I know that that's a tree", pointing to a tree that is near us. Someone else arrives and hears this, and I tell them: "This fellow isn't insane. We are only doing philosophy."

What, could ye not watch with me one hour? Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.

The operations of understanding thus divide the world into numberless polarities, and Hegel uses the expression 'isolated reflection' (isolierte Reflection) to characterize the manner in which understanding forms and connects its polar concepts. The rise and spread of this kind of thinking Hegel connects with the origin and prevalence of crucial relationships in human life. The antagonisms of 'isolated reflections' express real antagonisms. .... Isolation and opposition are not, however, the final state of affairs. The world must not remain a complex of fixed disparates. The unity that underlies the antagonisms must be grasped and realized by reason, which has the task of reconciling the opposites and 'sublimating' them in a true unity.

When I walk along with two others, they may serve me as my teachers. I will select their good qualities and follow them, their bad qualities and avoid them.

The chief error in philosophy is overstatement.

To-day the Enlightenment ideal has been changed into a reality; not only in legislation, which is the mere framework of public life, but in the heart of every individual, whatever his ideas may be, and even if he be a reactionary in his ideas, that is to say, even when he attacks and castigates institutions by which those rights are sanctioned.... The sovereignty of the unqualified individual, of the human being as such, generically, has now passed from being a juridical idea or ideal to be a psychological state inherent in the average man. And note this, that when what was before an ideal becomes a component part of reality, it inevitably ceases to be an ideal. The prestige and the magic that are attributes of the ideal are volatilised.

In my opinion, all things in nature occur mathematically.

If you want me to believe in God, you must make me touch him.

A widow, the mother of a family, and from her heart she produces chords to which my whole being responds.

I am obliged to confess that I do not regard the abolition of slavery as a means of warding off the struggle of the two races in the Southern states. The Negroes may long remain slaves without complaining; but if they are once raised to the level of freemen, they will soon revolt at being deprived of almost all their civil rights; and as they cannot become the equals of the whites, they will speedily show themselves as enemies.

Mass man is a phenomenon of electric speed, not of physical quantity.

Nowadays, to say that we are clever animals is not to say something philosophical and pessimistic but something political and hopeful - namely, if we can work together, we can make ourselves into whatever we are clever and courageous enough to imagine ourselves becoming. This is to set aside Kant's question "What is man?" and to substitute the question "What sort of world can we prepare for our great grandchildren?"

The For-itself, in fact, is nothing but the pure nihilation of the In-itself; it is like a hole of being at the heart of Being.

I have entered on an enterprise which is without precedent, and will have no imitator. I propose to show my fellows a man as nature made him, and this man shall be myself.

You venerate the saints, and you take pleasure in touching their relics. But you disregard their greatest legacy, the example of a blameless life. No devotion is more pleasing to Mary than the imitation of Mary's humility. No devotion is more acceptable and proper to the saints than striving to imitate their virtues.

There have been men before ... who got so interested in proving the existence of God that they came to care nothing for God himself... as if the good Lord had nothing to do but to exist. There have been some who were so preoccupied with spreading Christianity that they never gave a thought to Christ.

What are novels? What is the secret of the charm of every romance that ever was written? The first thing in a good novel is to place the persons together in circumstances which naturally call out the high feelings and thoughts of the character, which afford food for sympathy between them on these points - romantic events they are called. The second is that the heroine has generally no family ties (almost invariably no mother), or, if she has, these do not interfere with her entire independence. These two things constitute the main charm of reading novels.

Weisinger, a couple of years ago, made up the following story: "Isaac Asimov was asked how Superman could fly faster than the speed of light, which was supposed to be an absolute limit. To this Asimov replied, 'That the speed of light is a limit is a theory; that Superman can travel faster than light is a fact.'"

It seems as if marriage were the royal road through life, and realised, on the instant, what we have all dreamed on summer Sundays when the bells ring, or at night when we cannot sleep for the desire of living. They think it will sober and change them. Like those who join a brotherhood, they fancy it needs but an act to be out of the coil and clamour for ever. But this is a wile of the devil's. To the end, spring winds will sow disquietude, passing faces leave a regret behind them, and the whole world keep calling and calling in their ears. For marriage is like life in this - that it is a field of battle, and not a bed of roses.

Good bye, proud world! I'm going home; Thou art not my friend; I am not thine.

The 'public' is a phantom, the phantom of an opinion supposed to exist in a vast number of persons who have no effective interrelation and though the opinion is not effectively present in the units. Such an opinion is spoken of as 'public opinion,' a fiction which is appealed to by individuals and by groups as supporting their special views. It is impalpable, illusory, transient; "'tis here, 'tis there, 'tis gone"; a nullity which can nevertheless for a moment endow the multitude with power to uplift or destroy.

Most people, at a crisis, feel more loyalty to their nation than to their class.

Anxiety may be compared with dizziness. He whose eye happens to look down into the yawning abyss becomes dizzy. But what is the reason for this? It is just as much in his own eye as in the abyss, for suppose he had not looked down. Hence, anxiety is the dizziness of freedom, which emerges when the spirit wants to posit the synthesis and freedom looks down into its own possibility, laying hold of finiteness to support itself. Freedom succumbs to dizziness. Further than this, psychology cannot and will not go. In that very moment everything is changed, and freedom, when it again rises, sees that it is guilty. Between these two moments lies the leap, which no science has explained and which no science can explain. He who becomes guilty in anxiety becomes as ambiguously guilty as it is possible to become.

Even from their infancy we frame them to the sports of love: their instruction, behavior, attire, grace, learning and all their words azimuth only at love, respects only affection. Their nurses and their keepers imprint no other thing in them.

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.

When we can't dream any longer we die.

I suppose the body to be nothing but a statue or machine made of earth, which God forms with the explicit intention of making it as much as possible like us.

At different degrees, everything is pathology, except for indifference.

People praise virtue, but they hate it, they run away from it. It freezes you to death, and in this world you've got to keep your feet warm.

The antagonism between science and religion, about which we hear so much, appears to me to be purely factitious - fabricated, on the one hand, by short-sighted religious people who confound a certain branch of science, theology, with religion; and, on the other, by equally short-sighted scientific people who forget that science takes for its province only that which is susceptible of clear intellectual comprehension; and that, outside the boundaries of that province, they must be content with imagination, with hope, and with ignorance.

Our business in this world is not to succeed, but to continue to fail, in good spirits.

The average mind is slow in grasping a truth, but when the most thoroughly organized, centralized institution, maintained at an excessive national expense, has proven a complete social failure, the dullest must begin to question its right to exist. The time is past when we can be content with our social fabric merely because it is "ordained by divine right," or by the majesty of the law.

...this Jewish doctrine of the primacy of economic values has found the widest acceptance and been most whole-heartedly acted upon. From America it has begun to infect the rest of the world. We may be pardoned for wishing that the Jews had remained not forty, but four thousand years in their repulsive wilderness.

I have gained this by philosophy ... I do without being ordered what some are constrained to do by their fear of the law.

The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant.

As for Adler, I was much impressed by a personal experience. Once, in 1919, I reported to him a case which to me did not seem particularly Adlerian, but which he found no difficulty in analyzing in terms of his theory of inferiority feelings, although he had not even seen the child. Slightly shocked, I asked him how he could be so sure. "Because of my thousandfold experience," he replied; whereupon I could not help saying: "And with this new case, I suppose, your experience has become thousand-and-one-fold."

We are told that a utilitarian will be apt to make his own particular case an exception to moral rules, and, when under temptation, will see a utility in the breach of a rule, greater than he will see in its observance. But is utility the only creed which is able to furnish us with excuses for evil doing, and means of cheating our own conscience? They are afforded in abundance by all doctrines which recognise as a fact in morals the existence of conflicting considerations; which all doctrines do, that have been believed by sane persons. It is not the fault of any creed, but of the complicated nature of human affairs, that rules of conduct cannot be so framed as to require no exceptions, and that hardly any kind of action can safely be laid down as either always obligatory or always condemnable.

The needs of a human being are sacred. Their satisfaction cannot be subordinated either to reasons of state, or to any consideration of money, nationality, race, or colour, or to the moral or other value attributed to the human being in question, or to any consideration whatsoever. There is no legitimate limit to the satisfaction of the needs of a human being except as imposed by necessity and by the needs of other human beings. The limit is only legitimate if the needs of all human beings receive an equal degree of attention.

By far the most valuable things, which we know or can imagine, are certain states of consciousness, which may roughly be described as the pleasures of human intercourse and the enjoyment of beautiful objects. No one, probably, who has asked himself the question, has ever doubted that personal affection and the appreciation of what is beautiful in Art or Nature, are good in themselves; nor, if we consider strictly what things are worth having purely for their own sakes, does it appear probable that any one will think that anything else has nearly so much value as the things which are included under these two heads.

All human knowledge begins with intuitions, proceeds from thence to concepts, and ends with ideas.

In how many churches, by how many prophets, tell me, is man made sensible that he is an infinite Soul; that the earth and heavens are passing into his mind; that he is drinking forever the soul of God?

Who does not in some sort live to others, does not live much to himself.

Through laziness and cowardice a large part of mankind, even after nature has freed them from alien guidance, gladly remain immature. It is because of laziness and cowardice that it is so easy for others to usurp the role of guardians. It is so comfortable to be a minor!

The science of pure mathematics, in its modern developments, may claim to be the most original creation of the human spirit.

Whensoever therefore the legislative shall transgress this fundamental rule of society; and either by ambition, fear, folly or corruption, endeavour to grasp themselves, or put into the hands of any other, an absolute power over the lives, liberties, and estates of the people; by this breach of trust they forfeit the power the people had put into their hands for quite contrary ends, and it devolves to the people, who have a right to resume their original liberty, and, by the establishment of a new legislative, (such as they shall think fit) provide for their own safety and security, which is the end for which they are in society.

As we search as a nation for constructive ways to challenge racism and white supremacy, it is absolutely essential that progressive female voices gain a hearing.

Whatever bitterness and hate may be found in the movements which we are to examine, it is not bitterness or hate, but love, that is their mainspring. It is difficult not to hate those who torture the objects of our love. Though difficult, it is not impossible; but it requires a breadth of outlook and a comprehensiveness of understanding which are not easy to preserve amid a desperate contest. If ultimate wisdom has not always been preserved by Socialists and Anarchists, they have not differed in this from their opponents; and in the source of their inspiration they have shown themselves superior to those who acquiesce ignorantly or supinely in the injustices and oppressions by which the existing system is preserved.

One may be humble out of pride.
