"If therefore we will warily attend to the Motions of the Mind, and observe what Course it usually takes in its way to Knowledge, we shall, I think, find that the Mind having got any Idea, which it thinks it may have use of, either in Contemplation or Discourse; the first Thing it does, is to abstract it, and then get a Name to it; and so lay it up in its Store-house, the Memory, as containing the Essence of a sort of Things, of which that Name is always to be the Mark."
— 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.
