title: Top-down causation regarding the chemistry-physics interface: a sceptical view.
abstract: This article examines two influential authors who have addressed the interface between the fields of chemistry and physics and have reached opposite conclusions about whether or not emergence and downward causation represent genuine phenomena. While McLaughlin concludes that emergence is impossible in the light of quantum mechanics, Hendry regards issues connected with the status of molecular structure as supporting emergence. The present author suggests that one should not be persuaded by either of these arguments and pleads for a form of agnosticism over the reality of emergence and downward causation until further studies might be carried out.
