Descarte said 'I think therefore I am', or in the orginal Latin, cogito ergo sum.
Is this analytic a priori?
The evidence for it being analytic, is that the first statement 'I think' includes a reference to the thinking 'I'. Assuming that this statement is a predicate (is it?) then the conclusion must follow, as the 'I' is already part of the predicate.
But is it a priori, that is independent of the world? It appears so as we've deduced the conclusion of the statement without reference to any world.
Is this correct?
