Aristotle 
The Nicomachean Ethics of Aristotle 

Nicomachean Ethics focuses on the importance of habitually behaving virtuously and developing a virtuous character. Aristotle emphasized the importance of context to ethical behavior, and the ability of the virtuous person to recognize the best course of action. Aristotle argued that happiness and well being is the goal of life, and that a person’s pursuit of such, rightly conceived, will result in virtuous conduct. ‚EVERY art and every inquiry, and similarly every action and pursuit, is thought to aim at some good; and for this reason the good has rightly been declared to be that at which all things aim.‘ -Aristotle
