Envy lurks at the bottom of the human heart like a viper in its hole. РHonor̩ de Balzac

It is remarkable that jealousy of individual property in land often goes along with very exaggerated doctrines of tribal or national property in land. – William Graham Sumner

Jealousy contains more of self-love than of love. – Francois de La Rochefoucauld

Envy is a littleness of soul, which cannot see beyond a certain point, and if it does not occupy the whole space feels itself excluded. – William Hazlitt, Characteristics, 1823
