Help us make a difference!

We want to keep this website open and free, and without distracting advertisements. ‡

Your financial support can help us expand the site and provide more free tutorials for teachers and students all over the world.

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 ( 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!

‡ : The only exceptions are ads served by third-party videos and search results over which we have no control.
