You say that, and I'm aware of the historical context. But you cannot deny that the majority of the text is devoted to questions like which verbs are appropriate and how words as used in mathematics relate to their notions used in math. In my experience, logic falls into two catgeories: using math to study a formal system of logic; and determining "foundations for all math" and determining what is an "irreducible form of nature" and other such prosaic things (can the phrase "such that" be defined?). In my humble opinion, the former is mathematics and the latter philosophy.
