Neil deGrasse Tyson is a brilliant, modern-day Carl Sagan. He is also, if we are to judge solely by his Twitter account, a freshman philosophy major, tweeting from his dorm room and rolling blunts on top of his used copy of Plato's Republic.
Imagine, if you will, Neil deGrasse Tyson—celestial tie and all—sprawled across empty pizza boxes atop a twin bed, eyes glazed over as visions of Plato's cave and words like "dialectical" dance in his head. Suddenly, he realizes—he's done it. He's figured it out. Neil pulls out his phone, and starts to tweet.
Just wait until his Intro class hears about this.
