If mind be common to us all, the reason in virtue of which we are rational is also common; so too is the power which bids us do or not do. Therefore we have all a common law; and if so, we are fellow-citizens and members of some common polity. The Universe, then, must in a manner be a state, for of what other common polity can all mankind be said to be members? Wherefore it is from this common state that we derive our intellectual power, our reason, and our law; or whence do we derive them? For that which is earthy in me is derived from earth, my moisture from some other element, my breath and what is warm or fiery from their proper sources. And therefore, as nothing can arise from nothing or return thereto, my intellectual part has also a source.
