A Missing Reference in the Summa

[seeker_of_God]

In the Summa Theologiæ Ia.I.V ad 1, Aquinas refers to a quote from the Metaphysics, which I cannot for the life of me track down.

It may well happen that what is in itself the more certain may seem to us the less certain on account of the weakness of our intelligence, “which is dazzled by the clearest objects of nature; as the owl is dazzled by the light of the sun” (Metaph. ii, lect. i).

I have searched for the part in quotes, and cannot find it anywhere except in the Summa itself. By “Metaph. ii, lect. i,” I assumed he meant part 1 of book II of the Metaphysics, but I cannot find any such quote within that part.

It’s driving me nuts. Any idea?

Sorry, nevermind, just a translation difference:

For as the eyes of bats are to the blaze of day, so is the reason in our soul to the things which are by nature most evident of all.

That is the quote in my translation.
