Prose 31
The Logic of Contradictions
A logical principle is said to be an empty
or formal proposition because it can add
nothing to the premises of the argument it
governs. This leads to the logic of contra–
dictions. It is an anacoluthon to say that
a proposition is impossible because it is
self-contradictory. (It is also ambiguous.)
The definition of the possible as that which
in a given state of information (real or
pretended) we do not know not to be true
conceals another anacoluthon.
