In 1970 and 1971, Charles Eames gave the Charles Eliot Norton Lectures at Harvard University. At the lectures, the Eames viewpoint and philosophy are related through Charles' own telling of what he called "the banana leaf parable"", a banana leaf being the most basic eating utensil in southern India. He related the progression of design and its process where the banana leaf is transformed into something fantastically ornate. He explains the next step and ties it to the design process by finishing the parable with:
But you can go beyond that and the guys that have not only means, but a certain amount of knowledge and understanding, go the next step and they eat off of a banana leaf. And I think that in these times when we fall back and regroup, that somehow or other, the banana leaf parable sort of got to get working there, because I'm not prepared to say that the banana leaf that one eats off of is the same as the other eats off of, but it's that process that has happened within the man that changes the banana leaf. And as we attack these problems—and I hope and I expect that the total amount of energy used in this world is going to go from high to medium to a little bit lower—the banana leaf idea might have a great part in it.
