The Splintered Mind

Here. Comments welcomed, hoped for, treasured. Over the past couple years I’ve been working on a pair of books, AI and Consciousness and Humanlike: A Defense of AI Rights. I began circulating AI and Consciousness last fall, and it should appear with Cambridge Elements soon. Both experts’ and non-experts’ comments were extremely helpful in revising. Thanks so much!

In philosophy of mind, people sometimes say things like the following: If functionalism is true about consciousness, then digital computers could be conscious; all it requires is that they instantiate the right programs. And yes, most functionalists about consciousness do think that. But the claim about digital computer programs does not straightforwardly follow from functionalism alone.

Available here. Abstract: Future AI persons might both (1.) deserve moral consideration and rights fully equal with natural human persons, and (2.) have lifeways so radically different from ours as to break familiar patterns of moral thinking by violating our ordinary background assumptions. This article presents a series of thought experiments about strange AI persons, centering on a two-pronged worry featuring two types of “monster”.

Biological naturalists (e.g., Godfrey-Smith, Block, Searle, Seth) suggest that computers aren’t made of the right kind of stuff to be conscious. Consciousness, they suggest, requires a biological substrate that computers lack. It’s not always clear, however, exactly what property animal biologies have that computers lack or why that property matters. It helps, I think, to sort biological naturalism into two flavors.

... but collectively, we haven’t yet figured out how. Yet! Helen De Cruz and the 2+1 Experiment Thanks for reading The Splintered Mind! Subscribe for free to receive new posts and support my work.

Liberals about AI consciousness hold that we might soon (if we haven’t already) create genuinely conscious AI systems. Conservatives about AI consciousness hold that AI consciousness remains in the distant future if it’s possible at all. According to the Leapfrog Hypothesis, the first conscious AI will not have merely a dim glow of animal-like consciousness, but rich consciousness, similar to a human’s. Such an entity would deserve humanlike rights.

with Jeremy Pober Given the surge of interest in AI consciousness, the issue of “substrate independence” or “substrate flexibility” is now a hot topic in the metaphysics of mind. That is, does being conscious require having a particular material composition? Or can anything with the right type of functional structure and behavioral sophistication be conscious, regardless of what it’s made of? Biologicists say that biological details are crucial.

Some people have come to interact with ChatGPT as though it were a kind of friend or romantic partner. For instance, a 2025 New York Times article describes the case of Ayrin, a human who fell in love with her ChatGPT “boyfriend.” Ayrin is far from alone.

Human beings matter morally. We have moral standing. Our interests deserve consideration -- for our own sakes, and not just as means to ends. Good ethical decision-making requires valuing human lives. Most philosophers hold that humans have the highest moral standing. No entity matters more, and many matter less. It’s worse to kill a human than a dog or a frog or bacteria or a tree.
