Eudox presents the people who hold a view that "Any good thing is more worthy of choice when one good is added to it than its own." Thus, he believes that happiness is the most worthy of choice and with it the good of other virtues increased.On the contrary, people represented by Plato think that "pleasure is not the good". Later on, Aristotle compare hearth with happiness. Different what people would consider about heath, the criteria of happiness are different from people to people. For example, business person might see "wealthy" as a standard of happiness; students would regard high GPA as a measurement of happiness(some of my friends do). Also, as what Aristotle discusses in Chapter 4, pleasure is not a process. We can easily feel happy and suddenly in a down mood. There is no start and stop point foe happiness. Meanwhile, Aristotle says pleasure is not a replenishment.[I am quite confused here, as I keep reading, I realized in some tense, Aristotle do think pleasure is a replenishment....] And as he states at the end of Book V, happiness is the end of human affair.
Something interesting I found in book V: the foreign pleasure.
According to Chapter 5 "Foreign pleasure produce much the same result as pain, since they ruin the activity, though not in the same way". But to what reason people have to do the thing that make them painful. Well, in my own understanding, this foreign pleasure is a pleasure in a long run, but a pain in a short run. For me writing is the last thing I would do during the whole day, so I just finished 10 out of 18 blogs now. Writing is always my short whether in english or in Chinese. I am a friend who has the same problem as I have, but she is a good writer now. Practice makes perfect, and at the same time practice needs efforts and usually being lots of pains especially at the beginning. Same to work out. The process of work out is painful, but in the end it would help me keep fit and healthy.
Maybe that would be the reason why even though the foreign pleasure is painful, some people would still not avoid it.
