Theologus: Politicus

Here is today's distich by John Owen, with an English translation by Thomas Harvey, 2.43. Owen is reveling as usual in parallels in paradox. He says to the learned divine, "your knowledge" (scire tuum) is nothing unless someone else knows that you know. As for the politician, things are even worse because secrecy is crucial: if anyone else knows, your knowing is nothing!

Theologus: Politicus
Scire tuum nihil est, nisi te scire hoc sciat alter.
Si sciat hoc alter, scire tuum nihil est.

THE DIVINE. THE POLITICIAN
To know thine’s nothing, if not known ’tis known.
If known ’tis nothing then to know thine own.

The vocabulary is keyed to the DCC Latin Vocabulary list. There are only two words in this poem that are not on the DCC list:
