Ignorance of all things is an evil neither terrible nor excessive, nor yet the greatest of all; but great cleverness and much learning, if they be accompanied by a bad training, are a much greater misfortune.
PlatoHow well I remember the aged poet Sophocles, when in answer to the question, "How does love suit with age, Sophocles - are you still the man you were?" he replied, "Peace, most gladly have I escaped the thing of which you speak; I feel as if I had escaped from a mad and furious master."
Plato
