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. Clearly, then, we should count happiness as one of these activities that are choiceworthy in themselves, not as one of those choiceworthy for some other end.
Happiness is the act of living a virtuous life.
Only happiness we chose as an end in itself. Living a happy virtuous life takes effort . If happiness is an activity in accordance with virtue, it is reasonable to assume that it is in accordance with the highest virtue, and this will be the virtue of the best part of us. Happiness resides in our soul . The intellect is our most precious possession and contemplation our most highest and most continuous activity.
