"Jealousy is nothing more than a fear..." - Quote by Francois De La Rochefoucauld

“One may outwit another, but not all the others.”

“Old people love to give good advice; it compensates them for their inability to set a bad example.”

“A woman is faithful to her first lover for a long time - unless she happens to take a second.”

“Love that is not jealous is neither true nor pure.”

“Jealousy is bred in doubts. When those doubts change into certainties, then the passion either ceases or turns absolute madness.”

“I am jealous of everything whose beauty does not die.”

“But what if all the tranquility, all the comfort, all the contentment were now to come to a horrifying end?”

“My view is that it is desirable to be both loved and feared; but it is difficult to achieve both and, if one of them has to be lacking, it is much safer to be feared than loved.”

“Because of its phantom nature, and despite elaborate defense mechanisms, the ego is very vulnerable and insecure, and it sees itself as constantly under threat. This, by the way, is the case even if the ego is outwardly very confident.”
