1802, William Paley published Natural Theology in response to naturalists such as Hume, refining the ancient teleological argument (or argument from design) to argue for the existence of God. He argued that life was so intricately designed and interconnected as to be analogous to a watch. Just as when one finds a watch, one reasonably infers that it was designed and constructed by an intelligent being, although one has never seen the designer, when one observes the complexity and intricacy of life, one may reasonably infer that it was designed and constructed by God, although one has never seen God. The official eight Bridgewater Treatises "On the Power, Wisdom and Goodness of God, as manifested in the Creation" included the Reverend William Buckland's 1836 Geology and Mineralogy considered with reference to Natural Theology setting out the logic of day-age, gap theory, and theistic evolution. The computing pioneer Charles Babbage then published his unofficial Ninth Bridgewater Treatise in 1837, putting forward a thesis that God had the omnipotence and foresight to create as a divine legislator, making laws (or programs) that then produced species at the appropriate times, rather than continually interfering with ad hoc miracles each time a new species was required. By 1836 the anatomist Richard Owen had theories influenced by Johannes Peter Müller that living matter had an "organising energy," a life-force that directed the growth of tissues and also determined the lifespan of the individual and of the species. In the 1850s Owen developed ideas of "archetypes" in the divine mind producing a sequence of species in "ordained continuous becoming" in which new species appeared at birth. Late in 1844 the anonymous publication of Vestiges of the Natural History of Creation popularised the idea of divinely ordered development of everything from stellar evolution to transmutation of species. It quickly gained fashionable success in court circles and aroused interest in all sections of society. It also aroused religious controversy, and after initially being slow to respond, the scientific establishment attacked the book. It continued to be a best seller to around the end of the century. Herbert Spencer was a 19th-century English philosopher who developed ideas about the unifying concept of evolution across the natural and social sciences. Spencer is the first to develop a theory of cultural evolution and is considered by some to be the father of Social Darwinism. It is also he and not Darwin
