Oh boy, this is a good one from duke32:
I wrote the following:

I never professed him. I only pointed you to his works. I am
surprised you are not impressed, however, because Christians far and

And, as evidenced below, it seems to be impressive enough for YOU to
profess his "I think, therefore I am."

In response, duke32 wrote (nominated portion):

Nope, "I think therefore I am" is mine.
