Between Persons
In one line Watsuji held that a person exists in the between, in relationships, and that ethics studies how we live there.
Watsuji Tetsuro was a Japanese philosopher who worked alongside the Kyoto School. In his three-volume Ethics, published between 1937 and 1949, he started from the Japanese word for a human being, ningen. It is written with the characters for person and for between, or space.
Watsuji took the word as a clue. A human being, he argued, is never just a single self. We exist in betweenness, aidagara: the web of family, work, place and community that gives our actions their meaning. Ethics, for him, is the study of how we live in that between.
He did not dissolve the individual. The individual pulls away from the group to become someone, and the group draws the individual back; each negates the other, and neither wins outright. Life happens in that movement.
Go deeper
Watsuji also wrote Climate and Culture, which links ways of life to their landscapes, partly in reply to Heidegger’s focus on time. After the Second World War, critics argued that his stress on the whole, and on self-surrender to it, could serve state power, and his writings on the state are still debated. Later scholars point out that he denied any nation the right to impose its culture as superior.
The shared kitchen
Three flatmates argue about dishes. Each keeps a list of what the others have failed to do, and the arguments get sharper.
One suggests a different question: not who is right, but what kind of household they want to share. They agree on a simple rota and a weekly check. The dishes mattered less than the between they had been neglecting.
Try this today Describe one tension in your life as a relationship that needs care, not as a contest between you and the other person.
