“Barbusse has shown us that the Outsider is a man who cannot live in the comfortable, insulated world of the bourgeois, accepting what he sees and touches as reality.”

It is still a question of self-expression.

Context: The world accepts and follows the traditional approach. The primary cause of disorder in ourselves is the seeking of reality promised by another; we mechanically follow somebody who will assure us a comfortable spiritual life. It is a most extraordinary thing that although most of us are opposed to political tyranny and dictatorship, we inwardly accept the authority, the tyranny, of another to twist our minds and our way of life. So if we completely reject, not intellectually but actually, all so-called spiritual authority, all ceremonies, rituals and dogmas, it means that we stand alone and are already in conflict with society; we cease to be respectable human beings. A respectable human being cannot possibly come near to that infinite, immeasurable, reality.
