philosophy: [14] Greek phílos (a word of uncertain origin) meant ‘loving’. It has entered into an enormous range of English compounds, including philander [17] (adopted from a Greek word meaning ‘loving men’), philanthropy [17], philately, and philology [17], not to mention all the terms suffixed with -phil or -phile, such as Anglophile [19] and paedophile [20]. Philosophy itself means etymologically ‘loving wisdom’. It comes via Old French filosofie and Latin philosophia from Greek philosophíā, whose second element was a derivative of sophós ‘wise’ (source of English sophisticate).

philosophy (n.)youdaoicibaDictYouDict
c. 1300, "knowledge, body of knowledge," from Old French filosofie "philosophy, knowledge" (12c., Modern French philosophie) and directly from Latin philosophia and from Greek philosophia "love of knowledge, pursuit of wisdom; systematic investigation," from philo- "loving" (see philo-) + sophia "knowledge, wisdom," from sophis "wise, learned;" of unknown origin.
Nec quicquam aliud est philosophia, si interpretari velis, praeter studium sapientiae; sapientia autem est rerum divinarum et humanarum causarumque quibus eae res continentur scientia. [Cicero, "De Officiis"]


[Philosophical problems] are, of course, not empirical problems; but they are solved through an insight into the workings of our language, and that in such a way that these workings are recognized -- despite an urge to misunderstand them. The problems are solved, not through the contribution of new knowledge, rather through the arrangement of things long familiar. Philosophy is a struggle against the bewitchment (Verhexung) of our understanding by the resources of our language. [Ludwig Wittgenstein, "Philosophical Investigations," 1953]
Meaning "system a person forms for conduct of life" is attested from 1771.
