To Florus 3.88

But when something contrary to everyone’s opinion is introduced by an expression whose sound provides its whole support, a serious error is committed if its proper name is readily available but it is labeled with a borrowed, inexact term. When we are speaking of offspring, no one doubts that every person born has two parents, and this needs no corroboration. It will therefore not obstruct understanding if I say that someone was born from one person: my words will not so unsettle anyone that they think he could have been born without either a father or a mother.
