"As long as you work hard, no matter how deep the pestle is, it will grind into a needle", which has influenced countless people in China. Is it voluntarism? Or subjective idealism?
It is true to emphasize subjective initiative, but it cannot go against the laws of nature. Otherwise it is idealism. Iron pestle is an exaggerated way to emphasize the role of will, but it does not violate the laws of nature. It is voluntarism that man can conquer nature. This slogan seems to be shouted by people who emphasize materialism.
