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"]Meaning "system a person forms for conduct of life" is attested from 1771. Philosophize is attested from 1594.
A study that attempts to discover the fundamental principles of the sciences, the arts, and the world that the sciences and arts deal with; the word philosophy is from the Greek for “love of wisdom.” Philosophy has many branches that explore principles of specific areas, such as knowledge (epistemology), reasoning (logic), being in general (metaphysics), beauty (aesthetics), and human conduct (ethics).
