Quality. Quantity. These words,
though common in modern conversation, are in their origin wholly
scientific. Cicero accompanies his employment of the former with a sort
He states it to be, as it is, the translation
of the Greek
ποιότης, which he says is also a philosophical
word, not one of ordinary life. The latter (quantity) is the commoner in
modern conversation of the two, and is there sometimes abusively
employed to denote not any quantity, but a great one. In the true use
of the word the smallest is as much characterized by quantity as the
largest amount of anything.
