Historical footnote
Mar. 9th, 2016 06:41 amFrom Branson's "Rises, Falls and Contractions: The 19th Through 22nd Centuries", chapter 12:
21. The term "sanity" here is not used in the modern sense. Through the early 21st century, it denoted the idea that, given the same information, we would all come to the same small handful of coping methods, personalities and ways of going about our affairs. Someone who was even briefly acting outside of established convention in a way that wasn't clearly and immediately advantageous was colloquially "insane" or "crazy." Imprisoning the socially unconventional was standard; see chapter 16 for more details.
