There's been much ado about the divisiveness between Heidegger and Husserl fans on the one side, with Frege and Russell stalwarts on the other. I'm mostly amused by accounts of name-calling between Derrida and Searle. With regards to the C/A divide itself, there remains all too much disagreement about what the disagreement is, and I'm not, for the moment, very interested in an account of the debate.
What I'm curious about is if anyone can identify with any precision where, when, or with who the division began. The SEP's article on Consciousness and Intentionality seems to suggest it was Brentano who started it, but I'm not able to verify the veracity of such a claim with any degree of accuracy. Can anyone else?
