In celebration of the 125th year of the Proceedings, we are proud to present the first Virtual Issue of the Proceedings of the Aristotelian Society. The Virtual Issue is based upon an Online Conference on the theme of Truth that took place 12th–18th April 2013. This weeklong event featured papers from our back catalogue, commentaries on these papers delivered by contemporary philosophers, and an online-based discussion forum that was open to all. The Virtual Issue comprises the classic papers and commentaries from the conference.
