All Primary Philosophical Text

A primary text written by the philosopher or theorist whose ideas the atlas describes, cited as the original statement of an idea rather than a later account of it. Belongs here: An Essay Concerning Human Understanding, John Locke's own 1689 treatise cited directly for a claim about his epistemology. Does not belong here: a later scholar's account of that same idea, filed under Academic Philosophy Reference, and an encyclopedia summary of the idea, filed under Encyclopedia Article rather than here.
