For this invention of yours will produce forgetfulness in the minds of those who learn it, by causing them to neglect their memory, inasmuch as, from their confidence in writing, they will recollect by the external aid of foreign symbols, and not by the internal use of their own faculties. Your discovery, therefore, is a medicine not for memory, but for recollection,—for recalling to, not for keeping in mind.
Plato (c. 427–347 B.C.), Greek philosopher. Socrates, in Phaedrus, sect. 275.
Recounting the response of the Egyptian god Thamus to Theuth's invention of letters, Socrates continued, "You are providing for your disciples a show of wisdom without the reality. For, acquiring by your means much information unaided by instruction, they will appear to possess much knowledge, while, in fact, they will, for the most part, know nothing at all; and, moreover, be disagreeable people to deal with, as having become wise in their own conceit, instead of truly wise."
