From Measure Things are Said to Be Moderate-Sized.

Therefore now by common usage things small and mean are said to have measure, because some measure remains in them, without which they would no longer be moderate-sized, but would not exist at all. But those things that by reason of too much progress are called immoderate, are blamed for very excessiveness; but yet it is necessary that those things themselves be restrained in some manner under God who has disposed all things in extension, number, and weight.
