Organicism is the philosophical perspective which views the universe and its parts as organic wholes and - either by analogy or literally - as living organisms. It can be synonymous with holism. Organicism is an important tradition within the history of natural philosophy where it has remained as a vital current alongside reductionism and mechanism, the approaches that have dominated science since the seventeenth century. Plato is among the earliest philosophers to have regarded the universe as an intelligent living being (see Timaeus). Organicism flourished for a period during the era of German romanticism during which time the new science of biology was first defined by Jean-Baptiste Lamarck. Within modern-day biological sciences organicism is the approach that stresses the organization (particularly the self-organizing properties), rather than the composition, of organisms. John Scott Haldane was the first biologist to use the term to describe his philosophical views in 1917, after which it became well-accepted during the course of the 20th century.
