Full Idea
To declare that existence is absurd is to deny that it can ever be given a meaning; to say that it is ambiguous is to assert that its meaning is never fixed.

A Reaction
Absurdity precludes meaning, but being meaningless doesn't entail absurdity. Asteroids are meaningless. Presumably if existence is meaningless now (as in a depression), but it might possibly become meaningful, then it can't qualify as 'absurd'.
