A friend posted this in a comment on Facebook:


I think I get the general meaning, which is "This seems to have a deep meaning." But I'm fuzzy on the implications of しなくもない.

Is it a contraction of かも知{し}れない? Something else?

This is a double negation. It is a way of saying "する" with less certainty.

How does it compare with sentence patterns like でしょう and かもしれない in terms of expressing certainty? – Flaw May 8 '12 at 7:41
