Abstract
Psychosemantics consists of four chapters, a brief epilogue, and an appendix. The chapters explain and argue for the book's main thesis, which is that "We have no reason to doubt--indeed, we have substantial reason to believe--that it is possible to have a scientific psychology that vindicates commonsense belief/desire explanation". The epilogue offers a quasi-transcendental deduction of the innateness of our knowledge of human psychology. The appendix gives three updated and refined arguments for the thesis of its title, "Why There Still Has to Be a Language of Thought."
