For, after all, the foundation of our whole nature, and, therefore, of our happiness, is our physique, and the most essential factor in happiness is health, and, next in importance after health, the ability to maintain ourselves in independence and freedom from care.
Reading is merely a surrogate for thinking for yourself; it means letting someone else direct your thoughts. Many books, moreover, serve merely to show how many ways there are of being wrong, and how far astray you yourself would go if you followed their guidance. You should read only when your own thoughts dry up, which will of course happen frequently enough even to the best heads; but to banish your own thoughts so as to take up a book is a sin against the holy ghost; it is like deserting untrammeled nature to look at a herbarium or engravings of landscapes.
A man's knowledge may be said to be mature, in other words, when it has reached the most complete state of perfection to which he, as an individual, is capable of bringing it, when an exact correspondence is established between the whole of his abstract ideas and the things he has actually perceived for himself. His will mean that each of his abstract ideas rests, directly or indirectly, upon a basis of observation, which alone endows it with any real value; and also that he is able to place every observation he makes under the right abstract idea which belongs to it.
The vanity of existence is revealed in the whole form existence assumes: in the infiniteness of time and space contrasted with the finiteness of the individual in both; in the fleeting present as the sole form in which actuality exists; in the contingency and relativity of all things; in continual becoming without being; in continual desire without satisfaction; in the continual frustration of striving of which life consists. . . Time is that by virtue of which everything becomes nothingness in our hands and loses all real value.
We should be surprised that a matter that generally plays such an important part in the life of man has hitherto been almost entirely disregarded by philosophers, and lies before us as raw and untreated material.
Great minds are related to the brief span of time during which they live as great buildings are to a little square in which they stand: you cannot see them in all their magnitude because you are standing too close to them.
In order to increase his pleasures, man has intentionally added to the number and pressure of his needs, which in their original state were not much more difficult to satisfy than those of the brute. Hence luxury in all its forms; delicate food, the use of tobacco and opium, spirituous liquors, fine clothes, and the thousand and one things that he considers necessary to his existence.
Monotheistic religions alone furnish the spectacle of religious wars, religious persecutions, heretical tribunals, that breaking of idols and destruction of images of the gods, that razing of Indian temples and Egyptian colossi, which had looked on the sun 3,000 years: just because a jealous god had said, Thou shalt make no graven image.
Every state of welfare, every feeling of satisfaction, is negative in its character; that is to say, it consists in freedom from pain, which is the positive element of existence.
It is, indeed, only in old age that intellectual men attain their sublime expression, whilst portraits of them in their youth show only the first traces of it.
There are two things which make it impossible to believe that this world is the successful work of an all-wise, all-good, and at the same time, all-powerful being; firstly, the misery which abounds in it everywhere; and secondly, the obvious imperfection of its highest product, man, who is a burlesque of what he should be.
The mother of useful arts is necessity; that of the fine arts is luxury. For father the former has intellect; the latter genius, which itself is a kind of luxury.
If a person is stupid, we excuse him by saying that he cannot help it; but if we attempted to excuse in precisely the same way the person who is bad, we should be laughed at.
