Ethics in Masaryk’s classification of the sciences

Abstract Masaryk’s philosophical approach to reality is largely characterised by its orientation towards the positivism of Auguste Comte, which Masaryk sought to offset with the psychologism of J. S. Mill. The combination of these positivist approaches became the positive starting point for Masaryk’s ethics. But that was not the only influence on his ethics. Masaryk’s German translation of Hume’s book, titled Eine Untersuchung über die Prinzipien der Moral von David Hume (1883), reveals that the main stimuli that shaped Masaryk’s ideas about ethics came from David Hume. Although the need for scientific evidence became a fundamental principle of Masaryk’s thought, the need to objectively anchor ethics in rational theism necessitated in this area a departure from his positivist outlook. Masaryk’s lectures on practical philosophy attest to this fact. The reason for his departure from a positivist stance was due to the metaphysical nature of his concept of psychology.
