Key ideas
Key idea 1
Every choice points toward a good
Medicine aims at health, and shipbuilding aims at a ship. Aristotle begins with the thought that every activity seeks some good, but many goals serve a further purpose. If every desire led only to another desire, there would be no final target.
He calls the end wanted for its own sake the Chief Good, usually called happiness. People disagree about whether it means health, wealth, pleasure or honor. The first task is to ask what your smaller goals are really serving.
Key idea 2
Happiness is something you do
To understand happiness, Aristotle asks what human beings do that distinguishes them from plants and other animals.

Who it’s for
Readers who enjoy clear thinking about how to live, character, friendship and fairness will love this book. It also suits those drawn to the roots of Western moral philosophy.
What this book is
What is a good life for a human being, and how do you actually get one? Aristotle puts this question to his listeners in The Ethics, and he does not answer with a rule book. He asks what people really aim at in everything they do.
The Ethics was written in the fourth century before our era and is arranged in ten books. Aristotle treats it as political science, because the good of one person and the good of a city are close kin. His goal is not just to know what virtue is but to become virtuous. You will follow his argument in order, from the one end all actions aim at to the life of contemplation.

Every action aims at a final good
Aristotle opens with a simple observation. Every art, every science and every choice seems to aim at some good. Medicine aims at health, shipbuilding at a ship, and generalship at victory.
But these ends often serve something further. A bridle serves horsemanship, horsemanship serves war, and war serves the city. If we always chose for the sake of something else, desire would run on without limit. So there must be one end we want for its own sake, and everything else is wanted for its sake.
Aristotle calls this the Chief Good, and most people call it happiness. They disagree sharply about what it is. The sick person says health, the poor person says wealth, and others name pleasure or honor. He tests these answers and finds each wanting. Before asking how to act, ask what all your actions are for, because a clear target helps you hit it.
Name the final end you are really choosing for, and judge every smaller goal by it.
That’s 1 of 9 key points.

What is Aristotle's Ethics about?
It asks what the best life for a human being is and how to reach it. Aristotle answers with happiness as activity in line with virtue, shaped by habit, judgment, justice, friendship and reflection.

Aristotle means a flourishing life, not a passing mood. It is excellent activity of the soul over a complete life, with enough external goods such as friends and means to act well.
