"We may as well think the use of Reason necessary to make our Eyes discover visible Objects, as that there should be need of Reason, of the Exercise thereof, to make the Understanding see, what is Originally engraven in it"

Metaphor
"We may as well think the use of Reason necessary to make our Eyes discover visible Objects, as that there should be need of Reason, of the Exercise thereof, to make the Understanding see, what is Originally engraven in it"
Metaphor in Context
But how can these Men think the Use of Reason necessary to discover Principles that are supposed to be innate, when Reason (if we may believe them) is nothing else, but the Faculty of deducing unknown Truths from Principles or Propositions, that are already known? That certainly can never be thought innate, which we have need of Reason to discover, unless as I have said, we will have all the certain Truths, that Reason ever teaches us, to be innate. We may as well think the use of Reason necessary to make our Eyes discover visible Objects, as that there should be need of Reason, of the Exercise thereof, to make the Understanding see, what is Originally engraven in it. So that to make Reason discover those Truths thus imprinted, is to say, that the use of Reason discovers to a Man what he knew before; and if Men have these innate, impressed Truths Originally, and before the use of Reason, 'tis in effect to say that Men know, and know them not at the same time.

Citation
Locke began composition as early as 1671 (Drafts A and B).

I find over 25 entries in the ESTC (1690, 1694, 1695, 1700, 1706, 1710, 1715, 1721, 1726, 1731, 1735, 1741, 1748, 1753, 1759, 1760, 1765, 1768, 1775, 1777, 1786, 1788, 1793, 1795, 1796, 1798). See also the many abridgements issued in the period.

First published as An Essay Concerning Humane Understanding. In Four Books. (London: Printed by Eliz. Holt, for Thomas Basset, at the George in Fleetstreet, near St. Dunstan's Church, 1690). <Link to EEBO><EEBO-TCP>

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.
