All restraints upon man's natural liberty, not necessary for the simple maintenance of justice, are of the nature of slavery, and differ from each other only in degree.
Lysander SpoonerIf those persons, who fancy themselves gifted with both the power and the right to define and punish other men's vices, would but turn their thoughts inwardly, they would probably find that they have a great work to do at home; and that, when that shall have been completed, they will be little disposed to do more towards correcting the vices of others, than simply to give to others the results of their experience and observation.
Lysander SpoonerThe commerce of a free people is many times more valuable than that of slaves. Freemen produce and consume vastly more than slaves. They have therefore more to buy and more to sell. Hence the free states have a direct pecuniary interest in the civil freedom of all the other states. Commerce between free and slave states is not reciprocal or equal.
