Evolving via group selectivity left us with a strong urge to identify with groups and form packs. Unfortunately reason must battle this biological urge to simply agree with one another. Reason begins with disagreement as we posses an inability to say what the truth is and thus are left to disprove everything and accept the truth - or the closest we can get to it - is whatever is left. Analytical deduction- the basis of science and reason. 

Deliberation, engagement, and the boldness to disagree- what is missing in america today. PSU is socialist if they shut this down, but they don't deny this, in fact they spread flyers around campus advertising it. This school in many ways trains people to simply do what they are told and to fit into the surrounding area rather than think for themselves and to shape it.
