Note 504 — Chapter X

Footnote 504: (return) Between these two extreme theories there were offered two, apparently less extravagant, accounts of the nature and limits of human knowledge--one declaring that "Science(real knowledge) consists in right opinion" (δόξα ἀληθής), but having no further basis in the reason of man ("Theæstetus," § 108); and the other affirming that "Science is right opinion with logical explication or definition" (µετὰ λόχου), ("Theætetus," § 139). A close examination will, however, convince us that these are but modifications of the sensational theory. The latter forcibly remind us of the system of Locke, who adds "reflection" to "sensation," but still maintains that all on "simple ideas" are obtained from without, and that these are the only material upon which reflection can be exercised. Thus the human mind has no criterion of truth within itself, no elements of knowledge which are connatural and inborn.
