“O, our silly ways! Is knowledge worthless, unless someone else knows that you know it?”
o mores, usque adeone
scire tuum nihil est nisi te scire hoc sciat alter?
Editorial note: Like many Classicists (whether they will admit it or not), I am myself very favorably disposed to the cultivation of ornamental knowledge, especially in the form of fine Classical quotations which can be produced in conversation. Although I therefore disagree with Persius on this point, I will retain this quotation in memory for the disingenuous chastisement of other vain scholars.
