About this line

Horace wrote it refusing to swear loyalty to any school of philosophy — take no one’s word for it. Seventeen centuries later the Royal Society made it their motto and meant the same thing: evidence before authority, always.

Why we carry this line

I had a couple years of Latin in high school. I don’t remember a lot. But when I read this quote with the Latin and English, it was the perfect addition to our Quoteiac library.
