[PatrickHenry]

There are two different passages (by Aesculus) in which Prometheus describes his gifts to man. You posted a translation of the 2nd. Here's another translation from the 1st (it uses "sense" instead of "reason"):

but listen to the tale
Of human sufferings, and how at first
Senseless as beasts I gave men sense, possessed them
Of mind. I speak not in contempt of man;
I do but tell of good gifts I conferred.

[cornelis]

That is closer. This attention paid to nous (hardly Anaxagoras' nous) and phren (the heart--definitely not Kant's Vernunft then) allowed those who had ears to hear and those who had eyes to see a way to alleviate their sufferings through invention. Obviously it is sense perception brought to the operations of the mind. And yet stronger than all these arts produced by the attention to our heart and mind, there is anagke, the very thing that Zeus is blind to, but Prometheus sees. Herein lies the meaning of the play (where else?)

These manifold inventions for mankind I perfected, who, out upon't, have none- No, not one shift-to rid me of this shame.
