The theory of the mean is one of Aristotle's best-known pieces of ethical thinking. It can be found in his book The Nicomachean Ethics. It is at once strikingly simple and fiendishly difficult. In a nutshell, Aristotle said that virtues are a point of moderation between two opposite vices. For instance, the virtue courage lies between the two vices of cowardice and recklessness. Recklessness is too much confidence and not enough fear, cowardice is too much fear and not enough confidence, courage is just the right amount of both.

This can be expanded to most virtues and vices. Some other means that Aristotle laid out were temperance (or self-control), which lies between self-indulgence and a lack of sensitivity to your own needs, and modesty which is between bashfulness and vanity.
Pre-Christian Virtues

Some of the “virtues” may seem a bit odd to those brought up with a post-Christian worldview. Aristotle thinks you should have the “right amount” of pride, depending on your worth, and that humility is a deficiency of proper pride, and therefore a vice. He also thinks you should feel anger to the right extent – too little anger when someone dents your car and you don't have a proper respect for either your possessions or your own dignity.

As you may have noticed, the mean is about the proper emotional response to situations, rather than the proper actions. For Aristotle, virtue came from character. It is the character that makes you do the good deeds that is virtuous, not the deeds themselves. This school of moral thought is still around today and is called Virtue Ethics.
How to Find the Mean

There are some problems to get over if you're thinking of living your life according to the Golden Mean, however. Firstly, how do you find the mean? Aristotle makes it clear that he is not talking about a mathematical middle, but the perfect intermediate point with regard to ourselves. To adapt an example Aristotle gives, if a baby only needs a teacupful of food each day to thrive, and a fully grown adult needs three square meals, that doesn't mean the ideal amount is halfway in between. If you're old enough to be reading this, you probably need an amount a lot closer to the three square meals than the teacup.
