A pairing
Here are two opposite sentiments which form an interesting pair:
Amicus Plato, magis amica veritas.
(This is given in several forms and attributed to several different people. "Plato is [my] friend, but the truth is [my] better friend.")
Errare, mehercule, malo cum Platone quam cum istis vera sentire.
(This is definitely due to Cicero. "By Hercules [we might say 'by God'], I would rather be wrong with Plato than be right [believe the truth] with them..." Some translate: "I prefer to err with Plato...")
These two are sometimes contrasted, but I think not usually mentioned alongside one another.
