A handsome first edition of John Locke's landmark philosophical treatise, a cornerstone of Western philosophical thought, and the first “to estimate critically the certainty and the adequacy of human knowledge." (PMM) This copy with Elizabeth Holt's name in the imprint, traditionally considered the first issue, although recent scholarship has called into question the priority between this and the traditional second issue with the Bassett and Mory imprint. It has been estimated that between only 500-900 copies of the first edition were printed, largely of this Holt issue.
