Schleiermacher discovers in this dialogue indications of a positive result not plainly enunciated: but he admits that Aristotle did not discover them--nor can I believe them to have been intended by the author.[28] But most critics speak slightingly of it, as alike sceptical and sophistical: and some even deny its authenticity on these grounds. Plato might have replied by saying that he intended it as a specimen illustrating the process of search for an unknown _quæsitum_; and as an exposition of what can be said for, as well as against, many different points of view. The process of trial and error, the most general fact of human intelligence, is even better illustrated when the search is unsuccessful: because when a result is once obtained, most persons care for nothing else and forget the antecedent blunders. To those indeed, who ask only to hear the result as soon as it is found, and who wait for others to look for it--such a dialogue as the Lysis will appear of little value. But to any one who intends to search for it himself, or to study the same problem for himself, the report thus presented of a previous unsuccessful search, is useful both as guidance and warning. Every one of the tentative solutions indicated in the Lysis has something in its favour, yet is nevertheless inadmissible. To learn the grounds which ultimately compel us to reject what at first appears admissible, is instruction not to be despised; at the very least, it helps to preserve us from mistake, and to state the problem in the manner most suitable for obtaining a solution.
