As much as possible I offer my work as a gift. I put it online without a pay wall of any kind. Online course contributions are self-determined at the time you register for each. I also keep the site clean of advertising.

This means I rely on voluntary financial support for my livelihood. You may make a recurring gift or one-time donation using the form below, in whatever amount feels good to you. If your finances are tight at all, please do not give money. Visit our contact page instead for other ways to support this work.

Recurring Donations

Note from the team: Your recurring donation is a resource that allows us to keep Charles doing the work we all want him doing: thinking, speaking, writing, rather than worrying about the business details. Charles and all of us greatly appreciate them!

Donate Monthly

One-Time Donation

Your gift helps us maintain the site, offer tech support, and run programs and events by donation, with no ads, sales pitches, or pay walls. Just as important, it communicates to us that this work is gratefully received. Thank you!
