According to a second line of response, the apparent conceivability of the relevant states of affairs is merely apparent. To this end, the anti-haecceitist denies that individuals successfully conceive of or imagine the states of affairs required to establish haecceitism. Responses of this sort hold agents to be mistaken about the content of their imaginings and, as a consequence, mistaken in believing themselves to conceive of states of affairs that differ haecceitistically. Responses of this sort reject premises P1 or P2 or their analogues.
