Leroi-Gourhan's "Introduction to a Paleontology of Symbols" or Can Art Save Us From AI?


Leroi-Gourhan's

Chapter 10 of Gesture and Speech, "Introduction to a Paleontology of Symbols," marks a key inflection point in Leroi-Gourhan’s argument. Up to this point, the book develops a sweeping account of human evolution through biological form and function and the technical thresholds in which these are externalized: gesture, tool use, language, externalized memory. But here, the question turns: how can we account for art, not as a byproduct or anomaly, but as an expression that runs through, and potentially exceeds, these functional layers? And what happens to the human once these functions are externalized into machines and AI? (Keep in mind, this was published in '64!)

So we tried to to make sense of the layer metaphor that emerges here, and try to think through the previous arguments, but this time with art as something like a third form, co-emerging with gesture and speech. 

Here's a preliminary attempt to diagram this a bit. Very much open for debate...
