haecceitistically

[…] I am contemplating the possibility of being poor Fred in a world just life this one. The Haecceitist will suggest that I have in mind a qualitative duplicate of this world where the nonqualitative determinants of cross-identification somehow link me with the qualitative counterpart of Fred. But this distorts my thought: I thought not just that I might have lived Fred's life, but that I might have been Fred living Fred's life. […] I suggest that the possibility I have in mind is not a world that is like ours qualitatively but differs from ours Haecceitistically.
