 One such philosopher is Catharine Trotter Cockburn. Cockburn pens her Defence of Mr. Locke’s Essay of Human Understanding in  1702.[9]  In this text, Cockburn is responding to three pamphlets directed at Locke’s  Essay.[10]  These pamphlets take aim at Locke’s Essay rather broadly, and Cockburn’s Defence reflects this, but much is said about Locke on persons and their persistence conditions therein. Specifically, these pamphlets charge Locke with not proving that the soul is immortal, or threatening proofs of the immortality of the soul. They additionally charge that Locke’s view leaves us with the strange consequence that our souls are in constant flux, making it the case that we “awake with new souls each morning”. Given the importance of the soul, its persistence, and its immortality, to many traditional theories of personal identity, these objections are arguably intended to be objections to Locke’s picture of persons. Cockburn is quick to defend Locke, but proceeds carefully and thoroughly as she does so.
