Aristotle's ethics is here again definitely naturalistic (i.e., determined by the nature of the human and in accordance with nature) and teleological (i.e., the morality is not determined by the motive but by the aim and the good that the aim would actualize though our action. Morality depends upon how much the will and the action will bring about certain goods.)
For Aristotle, morality consists in doing certain actions, not because we see them to be right in themselves, but because we see them to be such that they will bring us nearer to the "good for the human." This teleological position is not consistent with Aristotle's own distinction between action or conduct which is valuable in itself and the production of the goods which derives values from the (instrumental) work of the action.
The end at which a particular action aims may be merely instrumental, so each action must have an ultimate end which is valuable in itself, and Aristotle infers that the ultimate end of all actions must be the same. The science which investigates this end is supposed to be political science, it is harder to determine what this ultimate end is.
In this inquiry, our approach is not deductive (unlike logic and mathematics) but inductive. Ethics reasons not from but to the first principles. We must start with what is familiar to us and work back from them to the underlying reasons; and "to give the necessary knowledge of the facts a good upbringing is necessary."
Aristotle accepts from the view of "the many" that the ultimate end of human life is happiness ( = well-being of the soul chapt. 7). The corresponding adjective of originally meant "watched over by a good genius or spirit," but its general usage is a good fortune with a special reference to material prosperity. Therefore, the English translation "happiness" which means a state of feeling, "differing from pleasure only by its suggestion of permanence, depth, and serenity," according to David Ross.
Just as today, the notion of happiness as the ultimate end of our life varies depending upon people's opinions. Aristotle examines and proceeds from the notion of happiness with more generality and more popularity to the highest and most uniquely human intrinsic happiness. Some say that it is pleasure. Others will identify it with wealth. Others, honor. We even may change our opinion at a different time of our life. Some ill people may say that it is health.
Pleasure is rather the end for slaves than freemen, while honor cannot be the end f life, for it depends on the giver and is not really our own decision. Honor seems to e aimed at assuring us of our virtue; so maybe moral virtue is the end of life. But Aristotle denies it by saying that moral virtue may be in inactivity and misery. Aristotle insists that is a kind of activity, which in itself is not a pleasure, although it naturally accompanies "pleasures," and further excludes misery.
If happiness is an activity peculiar to the human, it is neither the activity of growth or reproduction, nor of sensation, since these are shared by other beings below the human.
The activity uniquely human is, according to Aristotle, the activity of reason or that in accordance with reason. This is indeed an activity of virtue, which does not limit itself to moral virtues, but also intellectual ones. The happiness as the ultimate end of morality does not consist in virtue as such, but rather in activity according to virtue or in virtuous activity. Moreover, Aristotle contends, happiness must manifest itself over an entire life rather than merely a brief period.
Aristotle does not exclude for example pleasure, wealth or honor, etc. generally considered as happiness from the happiness, as they often by nature accompany his stipulated happiness as the activity of virtue.
