It is a quite remarkable fact that the great religions of the most civilized peoples are more deeply fraught with sadness than the simpler beliefs of earlier societies. This certainly does not mean that the current of pessimism is eventually to submerge the other, but it proves that it does not lose ground and that it does not seem destined to disappear.

A religion is a unified system of beliefs and practices relative to sacred things, that is to say, things set apart and forbidden-beliefs and practices which unite into one single moral community called a Church, all those who adhere to them.

It is not human nature which can assign the variable limits necessary to our needs. They are thus unlimited so far as they depend on the individual alone. Irrespective of any external regulatory force, our capacity for feeling is in itself an insatiable and bottomless abyss.

A society whose members are united by the fact that they think in the same way in regard to the sacred world and its relations with the profane world, and by the fact that they translate these common ideas into common practices, is what is called a Church. In all history, we do not find a single religion without a Church.

Man is only a moral being because he lives in society, since morality consists in solidarity with the group, and varies according to that solidarity. Cause all social life to vanish, and moral life would vanish at the same time, having no object to cling to.

Science cannot describe individuals, but only types. If human societies cannot be classified, they must remain inaccessible to scientific description.

There is a collective as well as an individual humor inclining peoples to sadness or cheerfulness, making them see things in bright or somber lights. In fact, only society can pass a collective opinion on the value of human life; for this the individual is incompetent.
