Morality is not an imposition removed from life and reason; it is a compendium of the minimum of sacrifices necessary for man to live in company with other men, without suffering too much or causing others to suffer.
When the taste is purified, the morals are not easily corrupted. Whatever injures the body, the morals, or the mind, will lessen or vitiate taste; thus, disorders of the body and violent passions of the mind, will do this, and so will also excessive care or covetousness; but above all, a habit of intemperance, and keeping low company will greatly deprave that which was once a good taste.
Bad company is like a nail driven into a post, which, after the first and second blow, may be drawn out with little difficulty; but being once driven up to the head, the pincers cannot take hold to draw it out, but which can only be done by the destruction of the wood.
Philosophy is not opposed to science; it behaves itself as if it were a science, and to a certain extent it makes use of the same methods; but it parts company with science, in that it clings to the illusion that it can produce a complete and coherent picture of the universe, though in fact that picture must needs fall to pieces with every new advance in our knowledge.
