It is Mortifying to suppose it possible that a people able and zealous to contend with the Enemy should be reduced to fold their Arms for want of the means of defence; yet no resources that we know of, ensure us against this event.
Thomas JeffersonThe movements of nature are in a never ending circle. The animal species which has once been put into a train of motion, is still probably moving in that train. For if one link in nature's chain might be lost, another and another might be lost, till this whole system of things should evanish by piece-meal; a conclusion not warranted by the local disappearance of one or two species of animals, and opposed by the thousands and thousands of instances of the renovating power constantly exercised by nature for the reproduction of all her subjects, animal, vegetable, and mineral.
Thomas Jefferson
