Notes on The Purloined Letter
"Nil sapientiae odiosus acumine nimio" (Seneca): "Nothing is so hateful to wisdom as an excess of cleverness"
Non distributio medii: a logical fallacy (fallacy of the undistributed middle).
"Il y a a parier que toute idee publique, toute convention recue, est un sottise, car elle a convenue a plus grand nombre.": you can bet on the fact that any idea and convention that is widely accepted is wrong, for it is simply convenient to the greatest number.
"Facilis descensus Averni": descent into hell is easy
"Un dessein si funeste/S'il n'est digne d'Atree, est digne de Thyeste": a scheme so hateful, if it is not worthy of Atreus, is worthy of Thyestes.
Atreus & Thyestes were twin brothers in Greek mythology. Thyestes sleeps with Atreus' wife; Atreus gets revenge by killing Thyestes' children and serving them to Thyestes in a stew which Thyestes eats. Thyestes then gets revenge by consulting an oracle, which advises to have a son who would then kill Atreus.
