Aquinas' Theory of Science

The paper deals with the theory of science in Aquinas' work. Great attention is paid to the division of sciences and scientific methodology in Aquinas' theory. Aquinas shows his theory particularly in the commentary to Boethius' De Trinitate. His approach is based on the conception of Aristotle's Analytica Posteriora, which is wholly different from the contemporary one. Science is considered as a quality of human mind that enables to deduce some conclusions from introspective knowledge of the essence of a thing.
