Help us make a difference!

We want to keep this website pleasant to use and completely free. That is why we refuse to run advertisements. The only exceptions are ads served by third-party videos and search results over which we have no control.

Your financial support can help us expand the site and provide more free resources for teachers and students all over the world. Many people have asked if we can offer a comprehensive online course on critical thinking providing a certificate upon completion. A large donation will enable us to do that.

Donations can be sent to the University of Hong Kong. Please see the instructions here. Designate your gift to the Faculty of Arts (Philosophy - Critical Thinking Web)". Please email Joe Lau (jyflau@hku.hk) if you have made a donation or if you would like to discuss how your donation is to be spent.

There are other ways to help too! We also welcome volunteers to translate our Miniguide to critical thinking into other languages!
