In celebration of the 125th year of the Proceedings we are proud to announce our first ever Online Conference of the Aristotelian Society: a week-long event featuring a classic paper a day from our back catalogue, each accompanied by a commentary by a contemporary philosopher and an online forum open to all. The commentary will stimulate discussion by highlighting the paper’s major themes and their continuing importance to current debates; signaling challenges to specific claims and arguments; and indicating thematic connections between the various papers.
