With this quoatation from Dr. Hutchins "if we would change the face of the earth, we must first change our own hearts" , he wanted to express two great thruths:
First, to change the exterior of something means nothing if there is not a change in the core.
Second, that we humans have a decisive influence in the future of our planet, and if we want to improve its condition, we must first truly believe in those changes. We must have the good deeds and intentions to improve the life condition in the planet.
