To enjoy the things we ought and to hate the things we ought has the greatest bearing on virtue of character. For these things extend right through life, with a weight and power of their own in respect both to virtue and to the happy life, since men choose what is pleasant and avoid what is painful. A life-long virtue of character and a happy life is maintained by always choosing the right things and avoiding the bad ones.
Every good is more worthy of choice along with another good than taken alone.
The Good is not pleasure per se and the pleasant life is better with wisdom . Since activities differ in goodness and badness, and some are to be chosen, some to be avoided, and some neutral, their pleasures can be classed similarly, because each activity has a pleasure proper to it. Activities and desires are virtuous or bad . The pleasures associated with them are also good or censurable . Some activities are necessary, i.e. choiceworthy for some other end, while others are choiceworthy in themselves.
