C.A. Macdonald's incisive note, ‘On the Unifier-Multiplier Controversy', gave me fresh thoughts regarding the method of actindividuation which he defends against Jonathan Bennett's and my own misgivings. I believe a second look at the Reductive Unifying account, in light of Macdonald's apology for it, will help us size up the issues, notably those involving causation and time.

I shall follow previous debaters and dwell upon examples of mayhem, where one individual kills another by carrying out a more rudimentary action. Here is Donald Davidson's case. A queen murders her royal husband by emptying a vial of poison into his ear as he sleeps. To be exact: she rotates her wrist, and the lethal drug cascades toward his ear.
