The Lure of the Forbidden

Tacitus, Annals 13.12.2 (tr. John Jackson):

The illicit is stronger than the licit.

praevalent inlicita.

The same, tr. J.C. Yardley:

The illicit is always more appealing.

Ovid, Metamorphoses 7.20-21 (tr. Frank Justus Miller):

                               I see the better and approve it,
but I follow the worse.

                             video meliora proboque,
deteriora sequor.
