Paulo Freire & Michel Foucault

So..I was walking in from my philosophy class in Hortense Powdermaker hall...when suddenly something caught my eye. While walking out, to my right was a quote from Michel Foucault. Right now i don't remember what the quote was exactly except that it had something to do with thought.

I thought it was interesting seeing how we just finished reading his essay Panopticism. I was about to continue walking until i looked further to the left and found another quote, by Paulo Freiere. I don't remember the quote at all as i was leaving. I was just thinking that these 2 quotes are side by side each other, and that we just did a comparative essay on works by these 2 people. I was also wondering how significant these people are, or why Prof.Less chose them as topics of reading and disucussion. I just found it interesting is all..
