The article considers A.F. Losev''s philosophy of music in the context ofhis entire religious worldview and as the part of hisChristian-Neoplatonic philosophy. Synthesizing Pythagorean-Platonic andRomantic musical doctrines, Losev concludes: music is the expression ofthe life of numbers, a meonic-hyletic element that rages inside numericconstructions. So it is necessary to analyse the concept of number inthe system of Neoplatonic thought. In the Neoplatonic hierarchy of theuniverse both numeric sphere and music are located at the source of allthe eidei, above them and (...) between the One (the first hypostasis) and theWorld Intelligence (the second hypostasis). Then music is considered inthe context of the relation between the uncreated Absolute (Tetrade A)and the created world (Tetrade B). Losev''s doctrine on the Tetrades Aand B (connected not by essence but by energies) is the importantmodification of Neoplatonism. Finally the article considers Losev''saccount of music in relation to the absolutized individual person. (shrink)
