Rather than getting bogged down in an essentially definitional issue, this entry will adopt a different strategy. It will outline a range of philosophical commitments of a generally naturalist stamp, and comment on their philosophical cogency. The primary focus will be on whether these commitments should be upheld, rather than on whether they are definitive of “naturalism”. The important thing is to articulate and assess the reasoning that has led philosophers in a generally naturalist direction, not to stipulate how far you need to travel along this path before you can count yourself as a paid-up “naturalist”.
