“What we must learn to do is to create unbreakable bonds between the sciences and the humanities. We cannot procrastinate. The world of the future is in our making. Tomorrow is now.”

Address to Polaroid employees at Symphony Hall in Boston, Massachusetts (5 February 1960), as quoted in Insisting on the Impossible : The Life of Edwin Land (1998) by Victor K. McElheny, p. 198
Context: The world is a scene changing so rapidly that it takes every bit of intuitive ability you have, every brain cell each one of you has, to make the sensible decision about what to do next. You cannot rely upon what you have been taught. All you have learned from history is old ways of making mistakes. There is nothing that history can tell you about what we must do tomorrow. Only what we must not do.

The Value of Science (1955)
Context: We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
... It is our responsibility to leave the people of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant as we are. If we suppress all discussion, all criticism, proclaiming "This is the answer, my friends; man is saved!" we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.
... It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.

1962, Address at Independence Hall
Context: Acting on our own, by ourselves, we cannot establish justice throughout the world; we cannot insure its domestic tranquility, or provide for its common defense, or promote its general welfare, or secure the blessings of liberty to ourselves and our posterity. But joined with other free nations, we can do all this and more. We can assist the developing nations to throw off the yoke of poverty. We can balance our worldwide trade and payments at the highest possible level of growth. We can mount a deterrent powerful enough to deter any aggression. And ultimately we can help to achieve a world of law and free choice, banishing the world of war and coercion.
