George Grote,
Plato and the Other Companions of Sokrates…
“ Yet whoever could not answer this question was wandering in darkness — had no standard by which his judgments were regulated, and which kept them consistent with one another — no rule which he knew and could stand by for the guidance of his life. Not knowing what Justice and Virtue are, it was impossible to be just and virtuous: not knowing what Good is, we not only fail to reach it, but are certain to embrace evil instead. Such a condition, to any one capable of thought, made life not worth having. ”
