Forms

φῐλόσοφος (philósophos) m or f (neuter φῐλόσοφον); second declension[1]

Etymology

It is a compound from Ancient Greek φίλος (phílos, “loving”) + σοφός (sophós, “wise”), “loving wisdom”;[1][2] the CGL derives its first part from the verb φιλέω (philéō, “to love”).[3] Beekes glosses it as one who loves the wise, or wisdom, eager for knowledge.[4]

σοφός (sophós) is unexplained: Beekes suggests it may be a substrate word, if it belongs with σάφα (sápha, “clearly”) and the name Σίσυφος (Sísuphos).[4] The origin of φίλος (phílos) is also uncertain.[4]

Earliest recorded meaning

Its first use is as an adjective in a fragment of Heraclitus, “men who love wisdom”.[5][4][6] According to Cicero and Diogenes Laertius, Pythagoras called himself φιλόσοφος, a lover of wisdom, rather than σοφός, wise.[5]

Semantic evolution

In Isocrates, Plato and Xenophon the noun means a lover of wisdom and a learned, educated man in general, Plato defines the true philosophers as those who love to contemplate the truth, and Xenophon opposes the philosopher to the σοφιστής (sophistḗs).[5][3] It soon became the name of a profession, and the philosopher was a stock figure of comedy.[5][3] As an adjective it described philosophical natures and discussions, Aristotle says that poetry is more philosophical than history.[5][3] Plutarch calls Aristotle simply “the philosopher”, and under the Roman Empire the title was given to the members of the Museum at Alexandria.[5]

The New Testament uses it of the Epicurean and Stoic philosophers.[7] Hesychius glosses it as one who has tried everything, eager to learn.[8]

It was borrowed into Latin as philosophus.[9] It survives in Modern Greek as a learned word, φιλόσοφος (filósofos), and its everyday sense of someone who takes things philosophically is a semantic loan from French philosophe.[10]
