Synthetic: Existence/Kant: every existential judgment is synthetic according to Kant. Synthetic judgments a priori/Kant: make conditional existence assertion. (> Analogies of experience) - ChisholmVs.
Synthetic a priori/Kant: E.g. the space is three-dimensional. - RiemannVs: refuted - synthetic a priori/Chisholm: depends on whether there are non-analytic propositions of the form All S are P. - E.g. Chisholm: All squares are form-bearing, all red is colored, nothing red is green. - But not clearly: two forms: a) all humans are mortal, b) all humans are descendants.
Chisholm: form-identical with the analytical propositions - KantVsChisholm: form differs.
Synthetic a priori/Chisholm/Sauer: Problem: no synthetic a priori if the definition of necessity is: p expresses a contradictory proposition which can be negated - false solution: to chose necessity as mere inclusion (understanding a includes understanding b), then contradiction: it would be possible that there is no or one possible worlds , so that non-p. - reason: E.g. "p" expresses an inclusion, then non-p is contradictory.
Synthetic a priori/Chisholm/Sauer: E.g. (S) All red is colored: is not a logical truth because there are no red objects in every possible world (poss.w.). - analytic/Sauer: Problem: the same happens with the analysis: from the fact that (A) "all squares are rectangles" is analytic, would follow that this is true in every possible world, but not from the simple sentence "All squares are rectangles". - but: see below.
If "all squares are rectangular" is true, then the property of the square exists.
The doctrine of the synthetic a priori in Kant is VsEmpiricism. The doctrine of the analytic is VsRationalism: to reach the knowledge of objects by means of consistent thinking. - ((s) No existence follows from this.)
