Every deprivation of freedom is a species of servitude or slavery

Slavery has been, and, from the nature of man, must ever be, a common and general situation of life … . It is certain that, in civil society, every man is restrained of some part of his natural liberty, and is consequently in some degree deprived of his freedom. Every deprivation of freedom is a species of servitude or slavery.
~ Gilbert Francklyn (1789)
