Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use
of the book of the world.
Our moral virtues benefit mainly other people; intellectual virtues, on the other hand, benefit primarily ourselves; therefore the former make us universally popular, the latter unpopular.
There are, first of all, two kinds of authors: those who write for the subject's sake, and those who write for writing's sake. The first kind have had thoughts or experiences which seem to
them worth communicating, while the second kind need money and consequently write for money.
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.
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.
As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value than a much smaller amount if you have not thought it over for yourself.
Money is human happiness in the abstract; he, then, who is no longer capable of enjoying human happiness in the concrete devotes himself utterly to money.
Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him. It is for this reason chiefly that we have philosophy and religion.
The greatest wisdom is to make the enjoyment of the present the supreme object of life; because that is the only reality, all else being merely the play of thought. On the other hand, such a course might just as well be called the greatest folly: for that which in the next moment exists no more, and vanishes utterly, like a dream, can never be worth a serious effort.
