Great men and founders of religion usually manifest one of two things: either a sublimation or a norm. Christ, for example, is a sublimation in the sense that he represents the “otherworldly” in the world, hence Christians consider themselves “in the world but not of it,” and the idea that Christ’s Kingdom is not of this world. Buddha is also in this category, as are all the ascetics and hermits. The other path, that of a norm, is represented by Mohammed, Moses, and Abraham, who brought a social order and way of living to a people in addition to a religious life.
The Western mentality is essentially Christian, and this applies even to atheists, since we are dealing with characteristics of the mind and not with any specific ideas or beliefs.
