"Whenever I hear any one arguing for slavery I feel a strong impulse to see it tried on him personally."
-- Abraham Lincoln
A person who can acquire no property can have no other interest but to eat as much and to labour as little as possible.
-- Adam Smith
Although slavery sometimes had an ethnic basis, it was no great respecter of race. Muslim slavers traded in Christians: Georgians, Circassians, Armenians, and others. Christians, for their part, enslaved Moors: as late as the sixteenth century, hundreds of thousands of Muslim slaves toiled on Spanish plantations. On the eve of the American Civil War, there were three thousand black slave owners in the United States.
-- Daniel Hannan
You think that my use of the word 'slave' sounds a little over-stated? Think about it for a moment. We work for them. We do what we are told. We have no control over our lives."
-- Vernon Coleman
No man can properly control another if you are against slavery.
Now think what government does?
TENANTS AT WILL
tenants at will. They were all, or almost all, slaves, but their slavery was of a milder kind than that known among the ancient Greeks and Romans, or even in our West Indian colonies. They were supposed to belong more directly to the land than to their master. They could, therefore, be sold with it, but not separately. They could marry, provided it was with the consent of their master; and he could not afterwards dissolve the marriage by selling the man and wife to different persons.
-- Adam Smith
"A voluntary slavery contract makes no more sense than if the “slave” had agreed to transfer “an absolute property right in his subjective beliefs and values."
-- Randy Barnett
"But by selling himself for a slave, he abdicates his liberty; he foregoes any future use of it, beyond that single act. He therefore defeats, in his own case, the very purpose which is the justification of allowing him to dispose of himself. He is no longer free; but is thenceforth in a position which has no longer the presumption in its favour, that would be afforded by his voluntarily remaining in it. The principle of freedom cannot require that he should be free not to be free. It is not freedom, to be allowed to alienate his freedom."
-- John Stuart Mill
