For this equilibrium now in sight, let us trust that mankind, as it has occurred in the greatest periods of its past, will find for itself a new code of ethics, common to all, made of tolerance, of courage, and of faith in the Spirit of men.

Looking back 25 years later, what I may say is that the facts have been far better than the dreams. In the long course of cell life on this earth it remained, for our age for our generation, to receive the full ownership of our inheritance.

It is the cells which create and maintain in us, during the span of our lives, our will to live and survive, to search and experiment, and to struggle.

Small bodies, about half a micron in diameter, and later referred to under the name of 'mitochondria' were detected under the light microscope as early as 1894.

The cell, over the billions of years of her life, has covered the earth many times with her substance, found ways to control herself and her environment, and insure her survival.

For over two billion years, through the apparent fancy of her endless differentiations and metamorphosis the Cell, as regards its basic physiological mechanisms, has remained one and the same. It is life itself, and our true and distant ancestor.

Is it absurd to imagine that our social behavior, from amoeba to man, is also planned and dictated, from stored Information, by the cells? And that the time has come for men to be entrusted with the task, through heroic efforts, of bringing life to other worlds?
