“At every level in our inventory, nothing seems special about our Earth, our Sun, our Galaxy, our Local Group. Evidently, mediocrity reigns throughout. Such is our niche in the Universe.”

“... nothing in Nature is black or white, few solutions are clean and clear; rather, reality, and especially our models of it, possess shades of gray throughout.”

“Evolution, energy, and ethics are the core elements that will guide us along the challenging path toward the Life Era: the first - evolution - because a good understanding of our universal roots and of our place in the cosmic scheme of things will help us create a feasible future course; the second - energy - because our fate will bear strongly on the ways that humankind learns to use energy efficiently and safely; and the third - ethics - because global citizenship and a planetary society are crucial factors in the survival of our species.”

“Not that chance dominated events in the early Solar System, for scientific determinism was also functioning. But chance is an essential factor in all evolutionary events, and the birth and development of our planetary system were not exceptions.”

“Though we might like to think so, humankind is not at any special, unique or privileged location in the gargantuan, perhaps infinite, Universe.”

“The two go hand in hand like a dance: chance flirts with necessity, randomness with determinism. To be sure, it is from this interchange that novelty and creativity arise in Nature, thereby yielding unique forms and novel structures.”

“Given enough time, even evolution evolves.”
