A Measure of Restraint, it talks of a 2-faced god: Janus. A god of doors, he illustrates the universal truth that with each door that we walk through, we progress through; we must open another door, the one that will lead us to the consequences of our actions. One of the physical laws of the universe is that every action has an equal and opposite reaction, that is everything that we do has a consequence of equal magnitude. This is exemplified well in the piece, where the pawn shop man's gamble with science is paid off in the lives of his family, and where the Curie's first breakthrough with a substance that would change humanity is foreshadowed with a massive amount of poisoning and blight.
Indeed, as technology and engineering progress society, the capacity for creativity broadens. As our limits become blurred, the ability to enhance the human race is heightened, but equally, our potential to destroy it. Like genetic engineering, it can lead to marvels that skyrocket our survivability into the eons of the future, as easily as it can end our existence right now. We must exercise caution, as to drink too greedily from the fountain of knowledge is to drown in it.
