Welcome to the Yorkshire Philosophical Society

The society was formed in 1822, when “natural philosopher” was the term used for a scientist, and our traditional name has been retained. We continue to pursue the aim of promoting the public understanding of science by providing a programme of lectures for the public, and activities for members, as well as awarding grants and prizes to qualifying organisations and students. We are also responsible for a number of publications, including our Annual Report.

Our lectures cover a wide range of subjects in the natural sciences, social sciences and archaeology, and take place in a friendly, welcoming environment with the opportunity to meet others with similar interests. We are grateful for the support of IET North Yorkshire for our lecture programme.

Lectures are free and open to all.  Non-members are invited to make a donation to help cover costs.  Children are welcome provided they are accompanied by a responsible adult.

Selected lectures are held on Zoom and recordings of some of these can be found on our YouTube channel.  If you accept the invitation to subscribe to the channel, you will be notified whenever new videos are added.

Explore our website, which will help you to find out more about our lectures, visits, social activities, and publications, and also provide you with a section of articles on many topics you might find interesting.
