In the movie The Seven Percent Solution, Freud and Holmes use different, but empirical methods to come to the same conclusions. Using empirical reasoning they converge on the same understanding of how a murder took place. In contrast ideologies diverge as people go off on different ideological tangents. Ideologies seem destined to diverge into increasingly fragmented sects.
Are Atheists converging on an increasingly common understanding? As faith based groups splinter into increasingly hostile sects, can Atheists expect to have an advantage as we rely on empiricism to become an increasingly cohesive group?
