A quote
The people are divided into tribes, the army into centuries. Whatever has grown to greater size is more easily identified if it is broken up into parts; but the parts, as I have remarked, must not be countless in number and diminutive in size. For over-analysis is faulty in precisely the same way as no analysis at all; whatever you cut so fine that it becomes dust is as good as blended into a mass again.
