 Philosophical naturalism  denotes a broad range of attitudes towards ontological questions. We use “teleonaturalism” to denote a similarly broad range of naturalistic accounts of teleology in biology that are united in rejecting any dependence on mental or intentional notions in explicating the use of the teleological terms in biological contexts. Thus, those who reject teleomentalism typically seek truth conditions for teleological claims in biology that are grounded in non-mental facts about organisms and their traits.
