Neil deGrasse Tyson is an astronomer, astrophysicist, author, and science educator.  He is truly one of the greats with a CV longer than some books.  He has written and spoken a lot and has documented opinions and statements about many things, most profound and easy to digest.  But he resists answering one question in the way many wish he would.  In today's quote, he cautions us to be careful in what we think we know of a person based on association.
