  The English words ‘representation’ and ‘to represent’ derive via Old French from the Latin words ‘repraesentatio’ and ‘repraesentare,’ but these are by no means commonly used words in classical Latin. In late ancient thought it is foremost Quintilian and Tertullian that uses the terms in a philosophically interesting way. It was not until the twelfth century Latin translation of Avicenna’s De anima that these terms became frequently used in connection with cognition and the mind or the intellective soul (see Lagerlund 2007b).
