 Just as the “waking and sleeping Socrates” passage, L-N 2.27.23 shows that there can be a change of person due to a change in consciousness, and this is the case even though there is no change in man. But, what Locke also makes clear through L-N 2.27.23 is that there can be a change of person even though there is no change in soul. Thus while many philosophers (including Plato, Rene Descartes, Samuel Clarke, etc.) think that one cannot be a person unless one has an immaterial soul, and the identity of persons rests in the identity of souls, Locke makes the bold move of pulling persons and souls apart.
