We have now encountered the first paradox of Stoicism, and can discern its origin in the identification of virtue with pure reason. In getting forth the novelties in Zeno's teaching, Cicero mentions that, while his predecessors had recognized virtues due to nature and habit, he made all dependent upon reason. A natural consequence of this was the reassertion of the position which Plato held or wished to hold, namely, that virtue can be taught. But the part played by nature in virtue cannot be ignored. It was not in the power of Zeno to alter facts. All he could do was to legislate as to names. And this he did vigorously. Nothing was to be called virtue which was not of the nature of reason and knowledge, but still it had to be admitted that nature supplied the starting points for the four cardinal virtues--for the discovery of one's impulses, for right endurances and harmonious distributions. From things good and bad we now turn to things indifferent. Hitherto the Stoic doctrine has been stern and uncompromising. We have now to look at it under a different aspect, and to see how it tried to conciliate common sense. By things indifferent were meant such as did not necessarily contribute to virtue, for instance health, wealth, strength, and honor. It is possible to have all these and not be virtuous, it is possible also to be virtuous without them. But we have now to learn that though these things are neither good nor evil, and are therefore not matter for choice or avoidance, they are far from being indifferent in the sense of arousing neither impulse nor repulsion. There are things indeed that are indifferent in the latter sense, such as whether you put out your finger this way or that, whether you stoop to pick up a straw or not, whether the number of hairs on your head be odd or even. But things of this sort are exceptional. The bulk of things other than virtue and vice do arouse in us either impulse or repulsion. Let it be understood then that there are two senses of the word indifferent-- (1) neither good nor bad (2) neither awaking impulse nor repulsion Among things indifferent in the former sense, some were in accordance with nature, some were contrary to nature and some were neither one nor the other. Health, strengths and soundness of the senses were in accordance with nature; sickness weakness and mutilation were contrary to nature, but such things as the fallibility of the soul and the vulnerability of the body were neither in accordance with nature nor yet contrary to nature, but just nature.
