I ,for one, applaud this professor. The "Littering to see if a community would pick up trash" line seems a little vague to me.. People should always question history. We have become so comfortable intrusting our Teachers, Parents and even Corrupt Government with their ideas of the truth. We don't think to question it. Even if a truth is questioned. People as a whole really just want to hold on to a collective calm. We get sucked into the daily routine of work and HBO to notice any ripples in our little mediocre ponds. Question EVERYONE ...QUESTION EVERYTHING! EVEN THIS....
