 Moreover, concerning (P2), since it would be odd (to say the least) to deny that human animals think while accepting that porpoises and porcupines do, and since we can assume that the human animal in your chair is not atypical of its kind, whatever reasons one has for accepting that various nonhuman animals think apply equally to the human animal in your chair. While there are those who deny (in a sense) that any animal can think (e.g., Descartes, Johnston, S. Shoemaker), their positions strain empirical credibility and/or depend on fairly sophisticated metaphysical machinery. At first glance, anyway, (P2) is much easier to accept.
