In "Life's irreducible structure" (1968),[6] Polanyi argues that the information contained in the DNA molecule is not reducible to the laws of physics and chemistry. Although a DNA molecule cannot exist without physical properties, these properties are constrained by higher-level ordering principles. In "Transcendence and Self-transcendence" (1970),[7] Polanyi criticises the mechanistic world view that modern science inherited from Galileo.
