For every excessive state whether of folly, of cowardice, of self indulgence, or of bad temper, is either brutish or morbid; the man who is by nature apt to fear everything, even the squeak of a mouse, is cowardly with a brutish cowardice, while the man who feared a weasel did so in consequence of disease; and of foolish people those who by nature are thoughtless and live by their senses alone are brutish, like some races of the distant foreigners, while those who are so as a result of disease (e.g. of epilepsy) or of madness are morbid.
