early life and how a young man gets entrammelled by a school before he is really able to judge, reminds us of what we hear said nowadays about the danger of a young man's taking orders before his opinions are formed. To this it was replied that a young man only exercised the right of private judgment in selecting the authority whom he should follow, and, having once done that, trusted to him for all the rest. With the analogue of this contention also we are familiar in modern times. Cicero allows that there would be something in it, if the selection of the true philosopher did not above all things require the philosophic mind. But in those days it was probably the case, as it is now, that, if a man did not form speculative opinions in youth, the pressure of affairs would not leave him leisure to do so later. The life span of Zeno, the founder of Stoicism, was from B.C. 347 to 275. He did not begin teaching till 315, at the mature age of forty. Aristotle had passed away in 322, and with him closed the great constructive era of Greek thought. The Ionian philosophers had speculated on the physical constitution of the universe, the Pythagoreans on the mystical properties of numbers; Heraclitus had propounded his philosophy of fire, Democritus and Leucippus had struck out a rude form of the atomic theory, Socrates had raised questions relating to man, Plato had discussed them with all the freedom of the dialogue, while Aristotle had systematically worked them out. The later schools did not add much to the body of philosophy. What they did was to emphasize different sides of the doctrine of their predecessors and to drive views to their logical consequences. The great lesson of Greek philosophy is that it is worth while to do right irrespective of reward and punishment and regardless of the shortness of life. This lesson the Stoics so enforced by the earnestness of their lives and the influence of their moral teaching that it has become associated more particularly with them. Cicero, though he always classed himself as an Academic, exclaims in one place that he is afraid the Stoics are the only philosophers, and whenever he is combating Epicureanism his language is that of a Stoic. Some of Vergil's most eloquent passages seem to be inspired by Stoic speculation. Even Horace, despite his banter about the sage, in his serious moods borrows the language of the Stoics. It was they who inspired the highest flights of declamatory eloquence in Persius and Juvenal. Their moral philosophy affected the world through Roman law, the great masters of which were brought up under its influence. So all pervasive indeed was this moral philosophy of the Stoics that it was read by the Jews of Alexandria into Moses under the veil of allegory and was declared to be the inner meaning of the Hebrew Scriptures. If the Stoics then did not add much to the body of Philosophy, they did a great work in popularising it and bringing it to bear upon life.
