About my writing

Breaking the chain of confusion

Better ways of thinking, feeling, and acting—around problems of meaning and meaninglessness; self and society; ethics, purpose, and value.

Meaningness is a hypertext book, being written gradually by David Chapman. The web site also includes standalone essays on the same topics, and a “metablog” of news and commentary.

The book begins with an appetizer. Or you might like to look at its table of contents. Or, you may prefer listening to the audio book version.

To support and encourage my writing, the newsletter offers a paid option, which also gets you posts with writing that is too much fun for my Serious Sites.

Other web sites

I present a unified story, in divergent styles, across several web sites, of which this is the main one.


Meta-rationality is skill in using systematic reasoning, in technical fields, that goes beyond formal rationality by taking into account contexts and purposes. In the Cells of the Eggplant is my book about leveling up your work by applying meta-rationality.

Artificial intelligence

Artificial intelligence is harmful and risky. Promises that it will somehow lead to a utopian future lack any specific substance. We can probably get its hypothetical benefits without the risks.

My book Better without AI explains what you can do to stop it.


I am, somewhat reluctantly, a Buddhist. Of an odd sort: “the opposite of whatever you’d expect” comes close. That sort of Buddhism shares central themes with Meaningness. I explain it elsewhere:

Greatest hits

I write mainly web books—expositions extended over dozens of web pages—rather than stand-alone essays. However, here are some popular individual pages, sampled from several sites:

YOU NEED MORE LUX and Seriously bright light vs. winter blahs
Not getting enough daylight causes the winter blahs. Supplementing with seriously bright indoor light—way more than regular, or “light therapy” lamps can produce—lessens or eliminates the blah. These two posts explain the theory, and the solution: industrial strength light supplements.
An appetizer: purpose
An introduction to the main ideas, via the question: What—if anything—is “purpose”?
Geeks, MOPs, and sociopaths in subculture evolution
Subcultures were the main creative cultural force from roughly 1975 to 2000, when they stopped working. Why?
Developing ethical, social, and cognitive competence
A summary of Robert Kegan’s model of adult development; and its personal, social, and cultural implications.
A bridge to meta-rationality vs. civilizational collapse
To prevent civilizational collapse, a bridge may be necessary—specifically for geeks—between systematic rationality and fluid, meta-rational understanding.
“Ethics” is advertising
Claims about ethics mainly function to make oneself attractive.
A first lesson in meta-rationality
Using Bongard problems to introduce patterns of intellectual insight that respect, but transcend, systematic rationality.

Podcast appearances

I’ve been invited onto many podcast episodes to discuss these themes.

About David Chapman

I did a PhD in artificial intelligence at MIT. My undergraduate degree was in math. I’ve also studied cognitive science, biochemistry, Old English and Ancient Greek literature. None of that qualifies me to write Meaningness, but it may explain a certain STEM-ish orientation, decorated with occasional literary jokes. The closest thing I’ve written to an autobiography explains how I became a fictional character in Ken Wilber’s philosophical novel about artificial intelligence.

I have founded, managed, grown, and sold a successful biotech informatics company. That may explain a certain practical orientation, and lack of interest in philosophical theories that depend on the world being very unlike the way it appears.
