Doctrine of the Mean

“By the absolute mean, or mean relative to the thing itself, I understand that which is equidistant from both extremes, and this is one and the same for all. By the mean relative to us I understand that which is neither too much nor too little for us; and this is not one and the same for all. ... And so we may say generally that a master in any art avoids what is too much and what is too little, and seeks for the mean and chooses it—not the absolute but the relative mean.”

Aristotle, Nichomachean Ethics II. 6-7

There is no one-size-fits-all formula for everyone. Moderation is relative to particular persons because each man or woman is unique.
