Scorn is thinking less highly of someone than is just, out of Hate.

Exp.: Overestimation, therefore, is an effect, or property, of Love, and Scorn an effect of Hate. And so Overestimation can also be defined as love insofar as it so affects a man that he thinks more highly than is just of the thing loved. On the other hand, Scorn can be defined as Hate insofar as it so affects a man that he thinks less highly than is just of him he hates. See P26 S.
