Men have been obliged to make for themselves a notion of what religion is, long before the science of religions started its methodical comparisons.

It is science, and not religion, which has taught men that things are complex and difficult to understand.

It is inadmissible that systems of ideas like religions, which have held so considerable a place in history, and to which, in all times, men have come to receive the energy which they must have to live, should be made up of a tissue of illusions.

The roles of art, morality, religion, political faith, science itself are not to repair organic exhaustion nor to provide sound functioning of the organs. All this supraphysical life is built and expanded not because of the demands of the cosmic environment but because of the demands of the social environment.

There are two types of men: the great and the small.

If religion has given birth to all that is essential in society, it is because the idea of society is the soul of religion.
