was nevertheless very difficult to discern that end whereon rightly each human appetite or desire might repose. There were then many ancient philosophers, the first and the chief of whom was Zeno, who saw and believed this end of human life to be solely a rigid honesty, that is to say, rigid without regard to any one in following Truth and Justice, to show no sorrow, to show no joy, to have no sense of any passion whatever. And they defined thus this honest uprightness, as that which, without bearing fruit, is to be praised for reason of itself. And these men and their sect were called Stoics; and that glorious Cato was one of them, of whom in the previous chapter I had not courage enough to speak. Other philosophers there were who saw and believed otherwise; and of these the first and chief was a philosopher, who was named Epicurus, who, seeing that each animal as soon as it is born is as it were directed by Nature to its right end, which shuns pain and seeks for pleasure, said that this end or aim of ours was enjoyment. I do not say greedy enjoyment, voluntade, but I write it with a _p_, voluptate, that is, delight or pleasure free from pain; and therefore between pleasure and pain no mean was placed. He said that pleasure was no other than no pain; as Tullius seems to say in the first chapter De Finibus. And of these, who from Epicurus are named Epicureans, was Torquatus, a noble Roman, descended from the blood of the glorious Torquatus mention of whom I made above. There were others, and they had their rise from Socrates, and then from his successor, Plato, who, looking more subtly, and seeing that in our actions it was possible to sin, and that one sinned in too much and in too little, said that our action, without excess and without defect, measured to the due mean of our own choice, is virtue, and virtue is the aim of man; and they called it action with virtue. And these were called Academicians, as was Plato and Speusippus, his nephew; they were thus called from the place where Plato taught, that is, the Academy; neither from Socrates did they take or assume any word, because in his Philosophy nothing was affirmed. Truly Aristotle, who had his surname from Stagira, and Xenocrates of Chalcedon, his companion, through the genius, almost Divine, which Nature had put into Aristotle, knowing this end by means of the Socratic method, with the Academic file, as it were, reduced Moral Philosophy to perfection, and especially Aristotle. And since Aristotle began to reason while walking hither and thither, they were called, he, I say, and his companions, Peripatetics, which means the same as walkers about. And since the perfection of this Morality by Aristotle was attained, the name of Academician became extinct, and all those who attached themselves to this sect are called Peripatetics, and these people hold the doctrine of the government of the World through all its parts: and it may be termed a catholic opinion, as it were. Wherefore it is
