We are not so smart. We are dumb. We are ignorant. We must maintain an open channel. I believe in limited government. I believe that government should be limited in many ways, and what I am going to emphasize is only an intellectual thing. I don't want to talk about everything at the same time. Let's take a small piece, and intellectual thing.
No government has the right to decide the truth of scientific principles, nor to prescribe in any way the character of the questions investigated. Neither may government determine the aesthetic value of artistic creation, nor limit the forms of literary or artistic creation. Nor should it pronounce on the validity of economic, historic, religious, or philosophical doctrines. Instead it has a duty to its citizens to maintain the freedom, to let those citizens contribute to the further adventure and development of the human race. Thank you.
