Abstract
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.
