Attributed to Aristotle
«“Amicus Plato, sed magis amica veritas” (“Plato is a friend, but truth is a greater friend”).»
Misattributed
Verdict
It is not in Aristotle's work
The idea is in Nicomachean Ethics I 6, 1096a16, but the Latin formula is not his. An ancient Life of Aristotle attributed to Ammonius transmits it as “Socrates is a friend, but truth is a greater friend”; Roger Bacon uses it with Socrates, Newton writes “amicus Plato, amicus Aristoteles, magis amica veritas”, and the version with Plato appears in Don Quixote.
