Sean Carroll's new book is (apparently at least partly) about model-dependent realism
Salon has an interview with Sean Carroll in which he discusses his new book, The Big Picture, which releases tomorrow (May 10th). Readers of this blog will no doubt be aware of my fondness for Hawking's model-dependent realism or what I consider to be a cognitive-science-based variation, Lakoff's embodied realism. And while I've often referenced Carroll's old blog post about free will as evidence he shares the basic ideas, some of his comments in the Salon interview certainly have a ring about them that should be familiar to anyone versed in those empirically responsible epistemologies:
Whether he ever mentions model-dependent realism by name in the book, I don't know yet (obviously); but he's certainly in the ballpark. Stephen Hawking essentially says that the question of what is 'real' is meaningless; what matters is the utility of a model in its ability to reliably describe and predict phenomena. Lakoff, similarly, suggests that we consider something to be 'real' when it has a theoretical ontology necessary to explain phenomena. I think Carroll is in good company.
