Doctrine that all natural phenomena are explicable by material causes and mechanical principles. A usually unconscious mental and emotional pattern that shapes behavior in a given situation or environment. Closely linked with materialism and reductionism, especially that of the atomists.
Universe reducible to completely mechanical principles—that is, the motion and collision of matter. Later mechanists believed the achievements of the scientific revolution had shown that all phenomenon could eventually be explained in terms of 'mechanical' laws, natural laws governing the motion and collision of matter that imply a thorough going determinism.
Man is measurable and predictable.
