Donald Davidson (philosopher)

Donald Herbert Davidson (March 6, 1917 – August 30, 2003) was an American philosopher. He served as Slusser Professor of Philosophy at the University of California, Berkeley, from 1981 to 2003 after having also held teaching appointments at Stanford University, Rockefeller University, Princeton University, and the University of Chicago. Davidson was known for his charismatic personality and the depth and difficulty of his thought. His work exerted considerable influence in many areas of philosophy from the 1960s onward, particularly in philosophy of mind, philosophy of language, and action theory. While Davidson was an analytic philosopher, and most of his influence lies in that tradition, his work has attracted attention in continental philosophy as well, particularly in literary theory and related areas.
Personal life.
Davidson was married three times. His first wife was the artist Virginia Davidson, with whom he had his only child, a daughter, Elizabeth (Davidson) Boyer. Following his divorce from Virginia Davidson, he married for the second time to Nancy Hirschberg, Professor of Psychology at the University of Illinois at Urbana-Champaign and later at Chicago Circle. She died in 1979. In 1984, Davidson married for the third and last time, to philosopher Marcia Cavell.
Swampman.
Swampman is the subject of a philosophical thought experiment introduced by Donald Davidson in his 1987 paper "Knowing One's Own Mind". In the experiment, Davidson is struck by lightning in a swamp and disintegrated; simultaneously, an exact copy of Davidson, the Swampman, is made from a nearby tree and proceeds through life exactly as Davidson would have, indistinguishable from Davidson. The experiment is used by Davidson to claim that thought and meaning cannot exist in a vacuum; they are dependent on their interconnections to the world. Therefore, despite being physically identical to himself, Davidson states that the Swampman does not have thoughts nor meaningful language, as it has no causal history to base them on.
The experiment runs as follows:
