They are crazy because the limits of sanity are set by what we can take seriously. This, in turn, is determined by our upbringing, our historical situation."

“On James's view, "true" resembles "good" or "rational" in being a normative notion, a compliment paid to sentences that seem to be paying their way and that fit with other sentences which are doing so.”
