Usage: When we use these words in a figurative sense, as
applicable to human beings, we think of beasts as mere
animals governed by animal appetite; and of brutes as
being destitute of reason or moral feeling, and
governed by unrestrained passion. Hence we speak of
beastly appetites; beastly indulgences, etc.; and of
brutal manners; brutal inhumanity; brutal ferocity.
So, also, we say of a drunkard, that he first made
himself a beast, and then treated his family like a
brute.
