If we turn away from knowledge and truth, we will not succeed. If we believe the worst and suspect the best, we alone will suffer. If we deny our progress, if we are against all of it, if we tear down our accomplishments, we will fill the world with sorrow, and we will blemish our own name with shame.
But if we are courageous and farsighted and farseeing, if we have no fear of the truth, if we seek only after light, then we and our children and our children’s children shall know the greatness of this wonderful, beautiful land we call America.

Lyndon B. Johnson (1908-1973) American politician, educator, US President (1963-69)
