Final answer:
Pythagoras valued music for its moral and educational power and believed in the 'harmony of the spheres,' suggesting that cosmic harmony was reflected in music, which could have profound effects on the soul and society.
Step-by-step explanation:
The idea that Pythagoras had about music and its use in society notably diverges from the option presented as A, which suggests music has no significant impact on societal harmony. Contrary to this, Pythagoras believed in the profound mitmoral and educational power of music, aligning more closely with option B. His philosophy encompassed the concept of the harmony of the spheres, which held that the planets and stars produced music as they moved in accordance with mathematical laws, embodying a cosmic harmony that reflected divine order. The influence of Pythagorean ideas extended beyond mathematics to include a holistic vision of the universe where numbers played a crucial role in explaining natural phenomena, including the harmonics in music, which he believed could have healing powers. Pythagoras' teachings also suggested that music had the potential to influence the soul, which he saw as immortal and subject to reincarnation, thus emphasizing the importance of music within the ethical and pedagogical life of the community.
