necessary vs. contingent
Domain: epistemology
Canonical Formulation: ?
Possible Formulation:
necessary: A necessary propostion is one that must
be true. It must be true via axioms of logic, laws of physics,
proofs of geometry etc.
Example: The sum of the interior angles of a planar
triangle add up to 180 degrees.
Either proposition A is true or it is not true.
The sum of the forces is equal to the product of mass and
acceleration.
contingent: A contingent proposition is one that is
neither necessarily false nor necessarily true or rather it is a
proposition that need not be true and yet need not be false.
Example: Tomorrow it will rain.
I will be alive tomorrow.
God exists.
