“If slavery, barbarism and desolation are to be called peace, men can have no worse misfortune. No doubt there are usually more and sharper quarrels between parents and children, than between masters and slaves; yet it advances not the art of household management to change a father’s right into a right of property, and count children but as slaves. Slavery, then, and not peace, is furthered by handing the whole authority to one man.”
Baruch Spinoza, Tractatus Politicus (1677; translated by A. H. Gosset, 1883), Ch. 6, Of Monarchy
