Stobaeus on Stoic Ethics 16

All good things are beneficial and well used and advantageous and profitable and virtuous and fitting and honorable; there is an affinity to them. 

Conversely, all bad things are harmful and ill used and disadvantageous and unprofitable and base and unfitting and shameful, and there is no affinity to them. 

The Stoics say that "good" is used in many senses; the primary sense, which plays a role like that of a source for the other senses, is that which is stated as follows: that from which it characteristically results that one is benefited, or he by whom it results that one is benefited, and what is good in the primary sense is the cause. 

The second sense is that in accordance with which it characteristically results that one is benefited.  

A more general sense, and one extending also to the previous cases, is that which is such as to benefit. 

Similarly, the bad too is defined in outline by analogy with the good: that from which, or by whom, it characteristically results that one is harmed, and that in accordance with which it characteristically results that one is harmed; more general than these is that which is such as to harm.
