        I also want to thank Mic. I first began thinking seriously about
Brouwer after reading Mic's articles on him.

        I did not advance the view. I said it was common, and that Brouwer
held a variant of it.

        The question is whether Brouwer was aware of this point and adapted
his thinking about intuitionism to it. I think not.
