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.

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.

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.

A guide to the information available on this site, and help to find it, can be found in the Website help link here or on the left.



This autumn some of our lectures will take place on Wednesday afternoons in the centre of York.  Owing to the Covid-19 situation some of our programme of lectures, talks and visits have moved online particularly in Winter.

Our office at the Lodge is currently open on Tuesdays between 11 am and 4 pm, but please telephone to check before making a special journey.  If visitors are able to wear a mask, this would be much appreciated.

Our quarterly newsletters are printed and sent to members without internet access. Follow the link above or on the left for online newsletters.

During the pandemic, the Geology Group has been providing a monthly series of notes for anyone interested in geology. Click the Geology Group link here or on the left to find a wealth of information and activities.

To contact us during this period, please email: info@ypsyork.org. (Post sent to the Lodge and messages left on our office voicemail will be dealt with but there may be a delay. Thank you for your patience.)
