Tertullian

“ There is impunity in erring, if there is no delinquency; although indeed to err it is itself an act of delinquency. [1] With impunity, I repeat, does a man ramble, [2] when he (purposely) deserts nothing. ”

“ Away with the man [8] who is ever seeking because he never finds; for he seeks there where nothing can be found. Away with him who is always knocking because it will never be opened to him; for he knocks where there is none (to open) . Away with him who is always asking because he will never be heard; for he asks of one who does not hear. ”
