There remains one more leading characteristic of the sage, the most striking of them all, and the most important from the ethical point of view. This was his innocence or harmlessness. He would not harm others and was not to be harmed by them. For the Stoics believed with Socrates that it was not permissible by the divine law for a better man to be harmed by a worse. You could not harm the sage any more than you could harm the sunlight; he was in our world, but not of it. There was no possibility of evil for him, save in his own will, and that you could not touch. And as the sage was beyond harm, so also was he above insult. Men might disgrace themselves by their insolent attitude towards his mild majesty, but it was not in their power to disgrace him. As the Stoics had their analogue to the tenet of final assurance, so had they also to that of sudden conversion. They held that a man might become a sage without being at first aware of it. The abruptness of the transition from folly to wisdom was in keeping with their principle that there was no medium between the two, but it was naturally a point which attracted the strictures of their opponents. That a man should be at one moment stupid and ignorant and unjust and intemperate, a slave and poor, and destitute, at the next a king, rich, and prosperous, temperate, and just, secure in his judgements and exempt from error, was a transformation, they declared, which smacked more of the fairy tales of the nursery than of the doctrines of a sober philosophy. PHYSIC We have now before us the main facts with regard to the Stoic view of man's nature, but we have yet to see in what setting they were put. What was the Stoic outlook upon the universe? The answer to this question is supplied by their Physic. There were, according to the Stoics, two first principles of all things, the active and the passive. The passive was that unqualified being which is known as Matter. The active was the Logos, or reason in it, which is God. This, it was held, eternally pervades matter and creates all things. This dogma, laid down by Zeno, was repeated after him by the subsequent heads of the school. There were then two first principles, but there were not two causes of things. The active principle alone was cause, the other was mere material for it to work on--inert, senseless, destitute in itself of all shape and qualities, but ready to assume any qualities or shape. Matter was defined as that out of which anything is produced. The Prime Matter, or unqualified being, was eternal and did not admit of increase or decrease, but only of change. It was the substance or being of all things that are. The Stoics, it will be observed, used the term "matter" with the same confusing ambiguity with which we use it ourselves, now for sensible objects which have shape and other qualities, now for the abstract conception of matter, which is devoid of all qualities.
