It is a characteristic of the human mind to hate the man one has injured.
It is found by experience that admirable laws and right precedents among the good have their origin in the misdeeds of others.
Men are more ready to repay an injury than a benefit, because gratitude is a burden and revenge a pleasure
Lust of power is the most flagrant of all the passions.
No hatred is so bitter as that of near relations.
In seasons of tumult and discord bad men have most power; mental and moral excellence require peace and quietness.
