9128 | It is propositional attitudes which can be a priori, not the propositions themselves [Sorensen] |
Full Idea: The primary bearer of apriority is the propositional attitude (believing, knowing, guessing and so on) rather than the proposition itself. A proposition could be a priori to homo sapiens but a posteriori to Neandethals. | |
From: Roy Sorensen (Vagueness and Contradiction [2001], 6.3) | |
A reaction: A putative supreme being is quite useful here, who might even see the necessity of Arsenal beating Manchester United next Saturday. Unlike infants, adults know a priori that square pegs won't fit round holes. |
9130 | Attributing apriority to a proposition is attributing a cognitive ability to someone [Sorensen] |
Full Idea: Every attribution of apriority to a proposition is tacitly an attribution of a cognitive ability to some thinker. | |
From: Roy Sorensen (Vagueness and Contradiction [2001], 6.3) | |
A reaction: The ability would include a range of background knowledge, as well as a sheer power of intellect. If you know all of Euclid's theorems, you will spot facts about geometrical figues quicker than me. His point is important. |
