The most powerful works are those that challenge our perception of reality.

The idea that we will make a society where literally everybody is graded, the good at the top, bad at the bottom, exactly done as it should be, is impossible.

True progress happens when we listen to both scientists and farmers.

The true discovery of America is before us. The true fulfillment of our spirit, of our people, of our mighty and immortal land, is yet to come.
