Which Indian philosopher proposed the theory of atomism, which later influenced the development of modern atomic theory?
-
Kapila
-
Kanada
-
Sankara
-
Ramanuja
B
Correct answer
Explanation
Kanada, also known as Kanabhuj, is credited with proposing the theory of atomism in ancient India. His work, 'Vaisheshika Sutras', presented the idea that all matter is composed of tiny, indivisible particles called 'paramanu', which influenced the development of modern atomic theory.
