The concept of "good" is one of the essential concepts of moral philosophy. The author focuses on the semantic analysis of the word "good" as it has been delivered by the representatives of Angloamerican moral philosophy of the fifties and the sixties (R. M. Hare and his opponents, P. Geach. Ph. Foot and G. H. von Wright). The analytic moral philosophy called attention to the fundamental ethical questions, such as Are moral norms justifiable?; How are they justifiable?; Are moral concepts and moral propositions transcendental by their nature, or are they intersubjective?
