Techne

In Ancient Greek philosophy, techne (Greek: τέχνη, romanized: tékhnē, lit. 'art, skill, craft'; Ancient Greek: [tékʰnɛː], Modern Greek: [ˈtexni]) is a philosophical concept that refers to making or doing. Today the modern definition and use of "practical knowledge" is similar to the Ancient Greek definition of techne, whereas the latter can include various fields such as mathematics, geometry, medicine, shoemaking, rhetoric, philosophy, music, and astronomy.

One of the definitions led by Aristotle, for example, is "a state involving true reason concerned with production".
