"How far such an one [one in whom "decrepid old Age" has blotted out Memory] (notwithstanding all that is boasted of innate Principles) is in his Knowledge, and intellectual Faculties, above the Condition of a Cockle, or an Oyster, I leave to be considered."
— Locke, John (1632-1704)

Searching first in a Past Masters edition based on the 12th Edition of Locke's Works and proofread against the 1959 Fraser edition. More recent searches in EEBO-TCP.
Reading John Locke's An Essay Concerning Human Understanding, ed. Peter Nidditch (Oxford, Oxford UP, 1975)--against which I have checked the text searched in Past Masters. Note, Nidditch's text is based on 4th ed. of 1700.
