What does "for" meaning in this sentence? I mean the word "for" after the colon mark.
A second difference from Quine is also important: for the crux of the Legal Realist position (at least for the majority of Realists) is that non-legal reasons (e.g., judgments of fairness, or consideration of commercial norms) explain the decisions.

For whatever reason, for can have the meaning of "because". You can blindly ignore it in the given example (because) it's just a copula connecting the two sentences. I'd say the author used non-legal reasons when opting for the colon, precisely because this use of for is somewhat irregular, not at all conforming to the regular accusative use of for. But it gives a nice doublette: "important for the crux" blended with "the crux is".
