Someone describes that sometimes he pretended to be a philosopher and occasionally he hit the nail on the head, but more often [then he used such words] "it's his own finger-nail he leaves black and blue.
--- Does it mean that more often his comments as a would-be philosopher were inaccurate?
He's developing the idea of nails and hammers - quite neat, really.
ps - 'black and blue' is an idiomatic phrase that means 'badly bruised'.

or it might be that his comments sort of worked against him; like made others laugh at him or something!
