Creating a Large Language Model of a Philosopher. (arXiv:2302.01339v1 [cs.CL])

Can large language models be trained to produce philosophical texts that are
difficult to distinguish from texts produced by human philosophers? To address
this question, we fine-tuned OpenAI’s GPT-3 with the works of philosopher
Daniel C. Dennett as additional training data. To explore the Dennett model, we
asked the real Dennett ten philosophical questions and then posed the same
questions to the language model, collecting four responses for each question
without cherry-picking. We recruited 425 participants to distinguish Dennett’s
answer from the four machine-generated answers. Experts on Dennett’s work (N =
25) succeeded 51% of the time, above the chance rate of 20% but short of our
hypothesized rate of 80% correct. For two of the ten questions, the language
model produced at least one answer that experts selected more frequently than
Dennett’s own answer. Philosophy blog readers (N = 302) performed similarly to
the experts, while ordinary research participants (N = 98) were near chance
distinguishing GPT-3’s responses from those of an “actual human philosopher”.
