In a forthcoming paper, John Schellenberg forwards the following argument: anatomically humans have been around 200,000 years. That's a very short span of time for any species, and only in the past few thousand years ago have we been reflecting on the world around us. If we our species survives even as long as Homo erectus did, we've only completed a very small part of a potentially long future of thinking about religion, metaphysics and other matters.
At present, philosophy of religion in the analytic tradition is quite narrowly focused:
"in the west – and I expect I am writing mainly for western readers – philosophy of religion has been largely preoccupied with one religious idea, that of theism, and it looks to be moving into a narrower and deeper version of this preoccupation, one focused on specifically Christian ideas, rather than broadening out and coming to grips with its full task."(p. 3).
Theism, in a generic, omni-property sort of way, is one position that philosophers of religion commonly defend. The other is scientific naturalism. These seem to be the only games in town:
"most naturalists too assume that theistic God-centered religion must succeed if any does. Naturalism or theism. These seem to be the only options that many see. The harshest critics of religion, including philosophers such as Daniel Dennett, seem to think their job is done when they have, to their own satisfaction, criticized personalistic, agential conceptions of a divine reality." (pp. 3-4).
At the end of 2013, I conducted a qualitative survey (summary here, but I am writing up the paper presently) among philosophers of religion. Next to a series of open questions, there was a question for open feedback. I was quite surprised to see so many philosophers of religion openly lament the lack of subject diversity in their discipline. Just a few choice examples written by anonymous respondents:
