When Berkeley lists what philosophers take to be the so-called primary qualities of material bodies in the Dialogues, he remarkably adds "gravity" to the more familiar list of size, shape, motion, and solidity, thereby suggesting that the received view of material bodies had already changed before the second edition of the Principia had circulated widely.
That is, from Locke's point of view, we know that human beings which are, or at least contain, material bodies with size, shape, motion and solidity, along with parts characterized by those qualities are capable of thought, but since we cannot discern how any material thing could possibly have that capacity, we conclude that God may have superadded that feature to us, or to our bodies.
