what would you look for as signs in a philosopher that he is an intj or an intp? like zizek and derrida and people who are always changing the signs in their systems would be more likely to be intps (Ti Ne), and gruff tyrannical proto-fascist heideggers, nietzsches, etc would be intjs (Ni Te)? more conceptual vs more systematic? is marx an intj? hegel?
what do you think wittgenstein was? i change my take and go with infj too. his entire life story is never feeling at home in the world. and he was a mystic at heart who hated systematic philosophy. he was poetic. "our language is like an ancient city..."
I thought I read somewhere that Hobbes was ISTJ or something like that.
Damm, beat me to it - except that it was my own deduction as I hadn't read that before! Definitely TJ, probably I from what we know of his personality, however an Ni primary seems a little unlikely given his strongly mechanistic philosophy, marked disdain for abstract reasoning, and apologism for authoritarian government and maintenance of what equated to the political status quo.

Could Jeremy Bentham, the brash early Utilitarian stuffy moralists of the time loved to hate, have been an ESTP? His dismissal of the notion of inherent rights as "nonsense on stilts" screams Se and Ti.
