[edit] Syllogisms
I don't follow. Syllogistic logic should be binary or dyadic: All A is B is a function of two variables, isn't it? Septentrionalis 20:07, 19 November 2006 (UTC)
- No. In modern notation "Every A is a B" would be rendered . Remember that A and B are (mondaic) predicates, not individuals. From a modern viewpoint, the problem of multiple generality is that one cannot usefully nest quantifiers without a formal machinery for speaking about multiary predicates.

[edit] MSO
as far as i know in monadic second order logic only the second order variables have arity 1. --84.148.78.213 19:29, 24 March 2007 (UTC)
