It is not a thing to be used indiscriminately, but it is good upon occasion: as now, for instance.
I put out my hand to feel the dark mass before me: I discriminated the rough stones of a low wall — above it, something like palisades, and within, a high and prickly hedge.
I listened long: suddenly I discovered that my ear was wholly intent on analysing the mingled sounds, and trying to discriminate amidst the confusion of accents those of Mr. Rochester; and when it caught them, which it soon did, it found a further task in framing the tones, rendered by distance inarticulate, into words.
As his curate, his comrade, all would be right: I would cross oceans with him in that capacity; toil under Eastern suns, in Asian deserts with him in that office; admire and emulate his courage and devotion and vigour; accommodate quietly to his masterhood; smile undisturbed at his ineradicable ambition; discriminate the Christian from the man: profoundly esteem the one, and freely forgive the other.
There are no more uses of "discriminate" in the book.
