Stobaeus on Stoic Ethics 21

And every good is worth choosing; for it is pleasing and approved of and praiseworthy. 

And every bad thing is worth avoiding. 

For the good, insofar as it stimulates reasonable choice, is worth choosing; and insofar as it is subject to choice without suspicion, it is pleasing. 

And, moreover, insofar as one would reasonably suppose that it is one of the products of virtue, it is praiseworthy.
