There are men who radiate a special charm. They attract without wanting to, —one must believe in their personality, and then there is a certain quality which repels. One is not conscious what it consists of, but it is there. They are branded with the brand of Art. So was Oscar Wilde,—so was Edgar Allan Poe.
It's from an essay on Edgar Allan Poe by the German author Hanns Heinz Ewers (translated by Adèle Lewisohn, 1917). I didn't understand the bold part. What do you think the author meant by believing their personality? I also didn't get why he said that they have a special charm in the first sentence and they have a repelling quality in the second? Isn't that contradicting?
