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.
Consider the Koran... this wretched book was sufficient to start a world-religion, to satisfy the metaphysical need of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests. In this book we find the saddest and poorest form of theism. Much may be lost in translation, but I have not been able to discover in it one single idea of value.
With health, everything is a source of pleasure; without it, nothing else, whatever it may be, is enjoyable...Healt h is by far the most important element in human happiness.
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.

There is only one healing force, and that is nature; in pills and ointments there is none. At most they can give the healing force of nature a hint about where there is something for it to do.
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. . .

Truth that is naked is the most beautiful, and the simpler its expression the deeper is the impression it makes; this is partly because it gets unobstructed hold of the hearer’s mind without his being distracted by secondary thoughts, and partly because he feels that here he is not being corrupted or deceived by the arts of rhetoric, but that the whole effect is got from the thing itself.
There is in the world only the choice between loneliness and vulgarity. All young people should be taught now to put up with loneliness ... because the less man is compelled to come into contact with others, the better off he is.
