I dislike commerce and abhor artificial scarcity. My whole purpose here is to distribute knowledge freely, so there will be no tiers or paywalls or any barriers of that kind. However, I've spent a lot of time and effort on this work over the past 40 years (e.g., I got a Ph.D. in it), and I hope I have enough time remaining to complete it. I'll work doggedly on it in any case. I can guarantee persistence, if not speed. Unfortunately, everything costs a bit of money. In particular, hosting this website, if not my time. If you think the work is worthy and you'd like to contribute, there is a patronage link below.

And, if you win a Grammy based on what I've done, be a decent fellow and send me a crate of champagne.
