The next steps in Hume's argument were prophetic of the later sciences of biology and of self-organization. Some forms of order, once hit upon, would support themselves for a very long time. Hume also anticipated Darwin. Scientific evidence of self-design. Science has taken up the torch.
Gravity is the most potent creator of order.
Gravity built on small fluctuations in the original smooth universe, and clumped matter into discrete blocks, from solar systems to galaxies and superclusters. Once gathered into sizeable stars, hydrogen began to burn, producing energy and building the heavier elements including carbon, oxygen and nitrogen. When the elements are present for a long enough time in a suitable environment, life, a self-replicating system of order, emerges. Through evolution, life generates creatures that seem remarkably well fitted to their environment. Yet evolution is not planned.
