Organicism is the philosophical position that states that the universe and its various parts (including human societies) ought to be considered alive and naturally ordered, much like a living organism. Vital to the position is the idea that organicistic elements are not dormant "things" per se but rather dynamic components in a comprehensive system that is, as a whole, everchanging. Organicism is related to but remains distinct from holism insofar as it prefigures holism; while the latter concept is applied more broadly to universal part-whole interconnections such as in anthropology and sociology, the former is traditionally applied only in philosophy and biology. Furthermore, organicism is incongruous with reductionism because of organicism's consideration of "both bottom-up and top-down causation". Regarded as a fundamental tenet in natural philosophy, organicism has remained a vital current in modern thought, alongside both reductionism and mechanism, that has guided scientific inquiry since the early 17th century.
Though there remains dissent among scientific historians concerning organicism's pregeneration, most scholars agree on Ancient Athens as its birthplace. Surfacing in Athenian writing in the 4th-century BC, Plato was among the first philosophers to consider the universe an intelligent living (almost sentient) being, which he posits in his Philebus and Timaeus. At the turn of the 18th-century, Immanuel Kant championed a revival of organicisitic thought by stressing, in his written works, "the inter-relatedness of the organism and its parts[,] and the circular causality" inherent to the inextricable entanglement of the greater whole.
