Our present work sets forth mathematical principles of philosophy. For the basic problem of philosophy seems to be to discover the forces of nature from the phenomena of motions and then to demonstrate the other phenomena from these forces. It is to these ends that the general propositions in books 1 and 2 are directed, while in book 3 our explanation of the system of the world illustrates these propositions.

As for politics, I'm an anarchist. I hate governments and rules and fetters. Can't stand caged animals. People must be free.

In politics, as in philosophy, my tenets are few and simple. The leading one of which, and indeed that which embraces most others, is to be honest and just ourselves and to exact it from others, meddling as little as possible in their affairs where our own are not involved. If this maxim was generally adopted, wars would cease, and our swords would soon be converted into reap hooks and our harvests be more peaceful, abundant, and happy.
