Logic Group

Edinburgh logic group is Philosophy Society’s weekly logic-related reading group, and a general PhilSoc hub for all things logical. Originally intended as a short series to gauge interest for a logic reading group in the 2020/21 academic year, and provisionally entitled the wordy Edinburgh University Philosophy Society Philosophy of Logic Reading Group, it had its first meeting in early April 2020. Turns out logic is fun, so Logic group has run continuously since then. In that time, we’ve discussed all sorts—normativity, intuitionsim, future contingents, anumāna, pluralism, and the catuṣkoṭi, as some examples—and look forward to exploring even more of the possible worlds (some impossible ones too).

Up-to-date information on upcoming Logic group events is available at the PhilSoc Facebook page. There’s also a channel on the PhilSoc Discord for discussion (get in touch for a join link).
