You shall not, for the sake of one individual, change the meaning of principle and integrity, nor endeavour to persuade yourself or me, that selfishness is prudence, and insensibility of danger security for happiness.

Context

“My dear Jane, Mr. Collins is a conceited, pompous, narrow-minded, silly man; you know he is, as well as I do; and you must feel, as well as I do, that the woman who married him cannot have a proper way of thinking. You shall not defend her, though it is Charlotte Lucas. You shall not, for the sake of one individual, change the meaning of principle and integrity, nor endeavour to persuade yourself or me, that selfishness is prudence, and insensibility of danger security for happiness. "I must think your language too strong in speaking of both," replied Jane; "and I hope you will be convinced of it by seeing them happy together. But enough of this. You alluded to something else. You mentioned two instances.” source
