Is Scientific Materialism enough to live happily?

[quote=Thus, the strange dichotomy of the most compassionate acts and the most barbaric both appearing to stem from the same religious impulses. In fact, they do not. Religious dogma and tradition inevitably stand in opposition (even thought they grow out of) the underlying philosophy being expressed in religious symbolism. The latter really doesn't change from one faith tradition to another. As Joseph Campbell puts it, they are "folk inflections of the elementary idea."

The former, on the other hand, is the source of much grief and violence.[/QUOTE]
Didn't Maslow have something to say about this phenomena? As I recall he saw that the followers of a person who had a peak experience, if they were "Non-Peakers" as it were, became the legalistic organizers, eventually eschewing the mystical experience altogether?
