Confound Quotes - page 2
All this is merely saying that he, in a degree once common, but now very unusual, threw his feelings into his opinions; which truly it is difficult to understand how any one who possesses much of both, can fail to do. None but those who do not care about opinions, will confound it with intolerance. Those, who having opinions which they hold to be immensely important, and their contraries to be prodigiously hurtful, have any deep regard for the general good, will necessarily dislike, as a class and in the abstract, those who think wrong what they think right, and right what they think wrong: though they need not therefore be, nor was my father, insensible to good qualities in an opponent, nor governed in their estimation of individuals by one general presumption, instead of by the whole of their character.
John Stuart Mill
Let me give two cautions. 1) The one is, that you keep them to the practice of what you would have grow into a habit with them, by kind words, and gentle admonitions, rather as minding them of what they forget, than by harsh rebukes and chiding, as if they were wilfully guilty. 2) Another thing you are to take care of, is, not to endeavour to settle too many habits at once, lest by variety you confound them, and so perfect none. When constant custom has made any one thing easy and natural to 'em, and they practice it without reflection, you may then go on to another.
John Locke
