Scientists and the symmetry principle: an email exchange with Steven Weinberg

Earlier this week I received an email from Steven Weinberg, the physicist whose book To Explain the World was critically reviewed by Steven Shapin earlier this year. I commented on Shapin’s review in this essay, and in the process I attributed errors to Weinberg that he disclaimed in his email. Weinberg asked that I publish his email, and my reply, on this blog. I was happy to oblige. As I point out in my reply, Weinberg’s reaction to my essay is an additional reason to adopt the symmetry principle that I defended in earlier posts. Expand post.
