Enneads VI.7: How Ideas Multiplied, and the Good
Sixth Ennead, Book Seven
The Eyes Were Implanted in Man by Divine Foresight
1When the (higher) Divinity, or (some lower) divinity, sent souls down into generation, He gave to the face of man eyes suitable to enlighten him, and placed in the body the other organs suited to the senses, foreseeing that (a living organism) would be able to preserve itself only on condition of seeing, hearing and touching contiguous objects, to enable it to select some, and to avoid others.
Senses Not Given to Man Because of Experience of Misfortunes
But can you explain this divine foresight? You must not believe that He would have begun by making (animals) who perished for lack of senses, and that later (the divinity) gave senses to man and other animals so that they could preserve themselves from death.
