A Replacement?

In class this week we talked about good and evil, the decline of religion and the ascendancy of the "spiritual." A question the professor threw out to us then that I'm only answering now is, what is religion's greatest potential alternative? What's replacing it?

There's some irony in answering this question in a social science class because in many ways, the answer to these questions is ... social science. 

Psychology and social psychology have not answered all the questions, but they have provided close-enough answers that the influence of religion has paled. They have answered the problem of evil with the medicalization of evil, a belief that much wrongdoing is due to illness rather than sin. Hard to compete with that.
