Pope Pius XII on the globe of earth:
"Today, there is not perhaps a problem, which may interest and occupy so much, the most eminent researchers of the modern world – physicists, chemists, astronomers, biologists and physiologists – and even the modern lovers of natural philosophy, as much as the subject of the laws which govern the order and action of matter, and of phenomena operating in our globe and in the universe. Indeed, fundamental questions are dealt with, whose solution is no less decisive for the object and aim of every natural science, as important also for the metaphysical comprehension, rooted in objective reality."
