No, not circular reasoning.
"Baked into the cake" because of this notion:
For it is written: “I will make the wisdom of the wise men perish, and the intelligence of the intellectuals I will reject.”
Where is the wise man?
Where is the scribe?
Where is the debater of this system of things?
Has not God made the wisdom of the world foolish?
The haughtiness of man blinds him from the truth Jesus Christ revealed. Hence, God is in effect blinding the 'wise'.
And further:
but God chose the foolish things of the world to put the wise men to shame;
and God chose the weak things of the world to put the strong things to shame;
and God chose the insignificant things of the world and the things looked down on, the things that are not, to bring to nothing the things that are,
so that no one might boast in the sight of God
So, as you can see, this isn't 'circular reasoning' but evidence (as it has occured as stated) that God is behind these writings.
