For example, from the beginning of his life you can see in a nursing child the signs of desire, of anger, and of temper. Then, it may be said, good and evil are innate in the reality of man, and this is contrary to the pure goodness of nature and creation. The answer to this is that desire, which is to ask for something more, is a praiseworthy quality provided that it is used suitably. So, if a man has the desire to acquire science and knowledge, or to become compassionate, generous and just, it is most praiseworthy. Therefore it is clear that creation is purely good.
Evil is always lack of life.
If the lower side of man's nature is disproportionately developed, the remedy is not less life for that side, but more life for the higher side, so that the balance may be restored.
