How this is to be done we have already said, but we may exhibit the same conclusion in another way, by inquiring what the nature of this virtue is.

Now, if we have any quantity, whether continuous or discrete, 25 it is possible to take either a larger [or too large], or a smaller [or too small], or an equal [or fair] amount, and that either absolutely or relatively to our own needs.

By an equal or fair amount I understand a mean amount, or one that lies between excess and deficiency.

By the absolute mean, or mean relatively 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 relatively 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.
