Last night I went to hear Ellen Dissanayake’s lecture, ‘The Deep Structure of the Arts’, which was about the role of art in human evolution. I went because I thought I should, cringing slightly because the whole thing sounded too damnably Mona-ish, and left feeling awkward—not because of the lecture or Dissanayake’s ideas (which were methodical and measured, although I craved a more emphatic statement of her argument), but because of the awkward atmosphere of the question time that followed.
