It is from John Mair's Historia Majoris Britanniae tam Angliae quam Scotiae, which appeared in 1521 "Circa haec tempora [Ricardi Primi], ut auguror, Robertus Hudus Anglus et Parvus Joannes latrones famatissimi in nemoribus latuerunt, solum opulentorum virorum bona deripientes.
BONA DEA, the "good goddess," an old Roman deity of fruitfulness, both in the earth and in women.
Now the first step in accurate progress from sense to reason, or true philosophy, is to frame a bona notio or accurate conception of the thing; but the received logic never does this.
See Gerhard, Ober Agathodamon and Bona Dea (Berlin, 1849).
The case of "The Bona," 1895 (P. 125) shows that the rules are in accord with English law upon the point.
