And Wisdom being manifold, pervading the whole world, and all human affairs, varies its appellation in each case. When it applies itself to first causes, it is called Understanding (νόησις). When, however, it confirms this by demonstrative reasoning, it is termed Knowledge, and Wisdom, and Science. When it is occupied in what pertains to piety, and receives without speculation the primal Word in consequence of the maintenance of the operation in it, it is called Faith. In the sphere of things of sense, establishing that which appears as being truest, it is Right Opinion. In operations, again, performed by skill of hand, it is Art. But when, on the other hand, without the study of primary causes, by the observation of similarities and by transposition, it makes any attempt or combination, it is called Experiment. But belonging to it, and supreme and essential, is the Holy Spirit, which above all he who, in consequence of [divine] guidance, has believed, receives after strong faith. Philosophy, then, partaking of a more exquisite perception, as has been shown from the above statements, participates in Wisdom.
