One aspect of these themes is how people think of values. Cultures influenced by Taoism, Buddhism and Confucianism see values as opposites, capable of being harmonised. Values are in constant flux and change because the flow of opposites keeps shifting. In sub-atomic physics, the most advanced of our sciences, it is now impossible to advance without complementarity of paradigms. As to Japan and rice, Japan consists of rather infertile rock with small, terraced paddies.
Rice growing areas also host many cultural festivals.
Since the work is seasonal, growers double as actors and tourist guides. Shinto religion is harvest celebrating. In Conrad's Heart of Darkness, Marlow journeys down a snaking river into the heart of Africa. But there are two journeys. One is geographical the other spiritual.
