Document Summary
Can there be synthetic propositions justified independent of experience: empiricism: no, no synthetic a priori propositions, apriorism: yes, there can be synthetic a priori propositions. Axioms themselves are self-evident in a apriori (not the case in empiricism) As theorems are based off the axioms. Problem with axioms: why should we consider them absolutely certain/infallible. Problem of axioms: propositions: analytic vs synthetic. Analytic propositions: definition that holds in all possible worlds (definite), deducible from definitions, cannot contradict the results of experiments or observations. Empirical: nobody thought there was empirical and analytical (if something is true by definition, why would you need to experience that?) Sometimes things happen for no reason whatsoever (this is both. Synthetic propositions: may or may not be true, its opposite is conceivable. Not deducible, can conceivable and accepted in modern society) contradict the results of experiments or observations. Only answer is because that"s how the world is, and you know the world is this way through experience.
