Abstract

According to constitution views of persons, we are constituted by spatially coinciding human animals. Constitution views face an ‘overpopulation’ puzzle: if the animal has my brain, there is another thinker where I am. An influential solution to this problem distinguishes between derivative and non‐derivative property possession: persons non‐derivatively have their personal properties, while inheriting others from their constituters. I will show that this solution raises a new problem, by constructing a puzzle with the absurd result that we instantiate certain properties incompatibly. In setting up the puzzle, I demonstrate the relevance of the bodily awareness and self‐awareness literatures to overpopulation puzzles.
