What am I?

Eric T. Olson has argued that any view of personal identity in terms of psychological continuity has a consequence that he considers untenable-namely, that I was never an early-term fetus. I have several replies. First, the psychological-continuity view of personal identity does not entail the putative consequence; the appearance to the contrary depends on not distinguishing between de re and de dicto theses. Second, the putative consequence is not untenable anyway; the appearance to the contrary depends on not taking seriously an idea that underlies a plausible view of persons that I call 'the Constitution View'. Finally, Olson's own "Biological View of personal identity" has liabilities of its own.
