circular common occurrences

i dont know about you guys, but i always spot things that seem to come back on them selves, ironies and strange observations that seem to make sense to me, but many people don't see or understand. an example of one I came up with recently

im fairly cynical. which arguably is a flaw in my character, to agree that being cynical is a flaw is looking at that cynicism cynically. but because that is a cynically view then that cynicism cannot be a flaw.

it works the same way a double negative works.

i just wondered if anyone else either:

1) has a countering argument to this conundrum

2) has similar ideas, and would like to share them

*edit* im sure things like this have a greater relevance to things on a large scale, but i cant quite figure it out; any ideas?
