Gilbert and Sarkar distinguish organicism from holism to avoid what they see as the vitalistic or spiritualistic connotations of holism. Dusek notes that holism contains a continuum of degrees of the top-down control of organization, ranging from monism (the doctrine that the only complete object is the whole universe, or that there is only one entity, the universe) to organicism, which allows relatively more independence of the parts from the whole, despite the whole being more than the sum of the parts, and/or the whole exerting some control on the behavior of the parts.
