"What is it that makes a Beast be a Creature of less Liberty than Man, but only that its natural Appetites more necessarily govern all its Actions, and that it is not indued with a Faculty of Reason, whereby to exert itself, and gain a Power or Liberty of over-ruling those Appetites?"
— Clarke, Samuel (1675-1729)
