Definition:
There are three forms of equivalency in philosophy. Material equivalency is used to
describe the state of two propositions which have the exact same truth value. Formal
equivalency is used to describe the situation when one proposition, p, can be deduced
from another proposition, q, alone. Logical equivalency is used when it is impossible
for two propositions to have a different truth value. Thus, to say "p = q" is a
tautology.
