Are Atheists "Philosophically Limited"....?

What on earth makes you think that atheists would rule out evidence related to the study of human nature?Someone who opts for a Faith in interpretation "x" of sect #18 of religion #287 would certainly be philosophically limited. Such a person would have ruled out more than 99.9 % of possible explanations of the universe.But lack of belief is not philosophically limiting.Atheism is not something that claims to explain the universe, existence and everything. An atheist could remain open to all possible explanations of the universe.

Atheists aren't, though. Perhaps, given that the thread asks "are atheists philosophically limited?", you should have looked up "atheism" rather than "materialism".Then, you would have found out that atheists can have a wide variety of philosophies, and that there are non-theistic religions with non-material beliefs that they can follow.They can also, so far as moral philosophy is concerned, follow versions of your religion. Christian Atheism!You, as a Christian theist, cannot be a Jain or a Buddhist. But there are atheists in these religions.Atheists can also be agnostic about anything they wish to be agnostic about, including gods, and most do have some level of agnosticism towards the existence of gods (they do not claim to know that there are no gods, just don't believe in any of them).Atheism in its broadest sense, which encompasses anyone who lacks belief in gods, doesn't really mean anything more philosophically than what it says.

You are wrong. Why not look up several definitions of atheism and articles on atheism. Try to avoid the ones by creationists. That would be a Physicalist. If you substitute any particular philosophy for the word "atheist" in the question asked in the O.P., and assume that atheists must limit themselves to it, then of course it will appear to you that atheists must be philosophically limited.Atheism is really just the natural default position towards all god concepts. It describes your position towards them all except the one you happen to believe in. It's easy not believing in Odin, isn't it? You are not really narrowing your philosophical view in any significant way in not believing in him, but you certainly would be narrowing your world view if you did believe that he and his brothers created us.
