The Stoics, it will be observed, were Evolutionists in their psychology. But, like many Evolutionists at the present day, they did not believe in the origin of mind out of matter. In all living things there existed already what they called 'seminal reasons,' which accounted for the intelligence displayed by plants as well as by animals. As there were four cardinal virtues, so there were four primary passions. These were delight, grief, desire and fear. All of them were excited by the presence or the prospect of fancied good or ill. What prompted desire by its prospect caused delight by its presence, and what prompted fear by its prospect caused grief by its presence. Thus two of the primary passions had to do with good and two with evil. All were furies which infested the life of fools, rendering it bitter and grievous to them; and it was the business of philosophy to fight against them. Nor was this strife a hopeless one, since the passions were not grounded in nature, but were due to false opinion. They originated in voluntary judgements, and owed their birth to a lack of mental sobriety. If men wished to live the span of life that was allotted to them in quietness and peace, they must by all means keep clear of the passions.
