Meditations, Book IV, Section 4:

If to understand and to be reasonable be common unto all men, then is that reason, for which we are termed reasonable, common unto all. If reason is general, then is that reason also, which prescribeth what is to be done and what not, common unto all. If that, then law. If law, then are we fellow-citizens. If so, then are we partners in some one commonweal. If so, then the world is as it were a city. For which other commonweal is it, that all men can be said to be members of? From this common city it is, that understanding, reason, and law is derived unto us, for from whence else? For as that which in me is earthly I have from some common earth; and that which is moist from some other element is imparted; as my breath and life hath its proper fountain; and that likewise which is dry and fiery in me: (for there is nothing which doth not proceed from something; as also there is nothing that can be reduced unto mere nothing) so also is there some common beginning from whence my understanding hath proceeded.

An alternative translation:

If our intellectual part is common, the reason also, in respect of which we are rational beings, is common: if this is so, common also is the reason which commands us what to do, and what not to do; if this is so, there is a common law also; if this is so, we are fellow-citizens; if this is so, we are members of some political community; if this is so, the world is in a manner a state. For of what other common political community will any one say that the whole human race are members? And from thence, from this common political community comes also our very intellectual faculty and reasoning faculty and our capacity for law; or whence do they come? For as my earthly part is a portion given to me from certain earth, and that which is watery from another element, and that which is hot and fiery from some peculiar source (for nothing comes out of that which is nothing, as nothing also returns to non-existence), so also the intellectual part comes from some source.
