The article examines the problem of the influence of ancient philosophy on various branches of modern sciences through the prism of the doctrines of such important philosophers of ancient times as Plato, Aristotle, Heraclid and Parmenides. In spite of disputes and mutual criticism in their time, the works of most philosophers have common roots and each of them is an invaluable foundation for the development of modern science and philosophy and and so on. The author asserts that G. Galilei lay the foundation of modern science base oneself upon the works of Plato, which influenced the further development of philosophy to this day and created a deep and original physical conception of the number. Also work of Heraclitus who, due to the dominance of the positivist-pragmatic worldview of philosophy, was not recognized in his time, but gave impetus to the development of the natural sciences of the present are of great importance. Parmenides, in his turn, was the first linguistic philosopher and his contribution to the development of modern languages is difficult to overestimate. In the article, the authors explore the common features and roots in the works of all noted philosophers of antiquity, and reveal that their knowledge and achievements could not be used at that time in full force due to the complete dominance of theocentrism. Nevertheless, it is pointed out that the classical model of science was formed under the influence of the intellectual, political and legal life of antiquity, which was based on the general idea of the mind, which, as the authors note, was largely divine.
