The term is relatively uncommon even in philosophical discussion, and is often erroneously equated with panpsychism despite notable differences between the two views,[1] that are evident in the etymologies of the two words: "panpsychism" derives from the Greek pan, "all", and psyche, "soul" or "mind" (the terms consciousness and experience being preferred in philosophy),[2] and implies the sentience of all things; hylopathism derives from hylo-, which is translated either as "matter" or "wood" depending on its context, and whose English equivalent is hyle,[3] and pathos, "emotion" or "suffering" (and, by extension, experience).[4] Hylopathism is thus not necessarily a belief in the universality of sentience, but rather in the derivation of sentience from matter.[5]
