Answer:
The ideas of three early sociological theorists continue to strongly influence the sociology of religion: Durkheim, Weber, and Marx.
Even though none of these three men was particularly religious, the power that religion holds over people and societies interested them all. They believed that religion is essentially an illusion; because culture and location influence religion to such a degree, the idea that religion presents a fundamental truth of existence seemed rather improbable to them. They also speculated that, in time, the appeal and influence of religion on the modern mind would lessen.
