 During the heyday of logical positivism in the twentieth century, it is interesting that while Moritz Schlick proposed that its demands for empirical verification would render propositions about God as meaningless, it would not rule out as meaningless propositions about life after death so long as they involved subjects having experiences.

In this section, let us consider whether there is empirical support for belief in an afterlife.
