In this article I argue that we do not need a strict definition of naturalism, but can satisfactorily describe the naturalistic stance or attitude in terms of hostility to seeing human beings as subject to powers or forces or laws of nature that go beyond those governing the rest of the empirical world. We are to be explained as the evolutionary products of natural processes. I argue that we should see our concepts as well in this light, and explore some examples of the way this attitude can illuminate questions of meaning.
