Welcome to the Yorkshire Philosophical Society

We regret that owing to the Covid-19 situation our programme of lectures, talks and visits has been temporarily suspended and our office at the Lodge has been closed. We will be following government advice on when to resume our normal activities. In the meantime we continue to administer the Society, to make plans for later in the year and for our bicentenary in 2022, and to share news and items of interest via this website. New dates are being added for new or postponed lectures etc. The May newsletter has been printed and sent to members without internet access. Follow the link for the online newsletters:
