For they do not despise all those of whom they think ill. For some men they consider unscrupulous, slanderous fraudulent, and dangerous; they do not despise them, it may be; but they do think ill of them.

Context

“And so they reverence and extol with the highest praises those men in whom they see certain pre-eminent and extraordinary talents; and they look down with contempt upon those who they think have no ability, no spirit, no energy. For they do not despise all those of whom they think ill. For some men they consider unscrupulous, slanderous fraudulent, and dangerous; they do not despise them, it may be; but they do think ill of them. And therefore, as I said before, those are despised who are "of no use to themselves or their neighbours," as the saying is, who are idle, lazy, and indifferent.
{37} On the other hand, those are regarded with admiration who are thought to excel others in ability and to be free from all dishonour and also from those vices which others do not easily resist.” source
