David Bohm’s legacy crosses the worlds of science and language. His championing of a causal interpretation of quantum physics led to lengthy conversations with Einstein, but it won him little respect among most scientists, who preferred the orthodox indeterminate approach espoused by Niels Bohring and Werner Heisenberg, the Copenhagen School theorists (and subjects of Michael Frayn’s Tony Award-winning play Copenhagen). In the early 1950s, Bohm stood fast against Senator Joseph McCarthy’s anti-Americanism inquiries, which seriously damaged his professional standing in the United States and caused him to live and work abroad until his retirement in 1987 and his death five years later.
Perhaps it was his insistence on seeing order in the universe or his deep principles in the face of McCarthyism that inspired Bohm to fashion his paradigm about the implicate order and undivided wholeness, through which he cogitates with remarkable lucidity about humanity’s transcendence beyond individual and collective domains to an immersion in a cosmic dimension. This unique fusion of science and society resides at the center of Dialogue, and Bohm devotes substantial space to it in On Dialogue, a slim and engaging treatise.
Dialogue is unlike discussion or debate, where demonstrating one’s acumen, outwitting an adversary, or winning a political advantage is paramount. It requires a different sort of reflection that strikes at the heart of self-awareness and empathetic discourse. As Bohm observes,
Thought should be able to perceive its own movement, be aware of its own movement. In the processes of thought, there should be the awareness of that movement, of the intention to think, and of the result which that thinking produces.
A seminal manifesto on communication breakthroughs, Bohm's book provides just the theoretical grounding that a Dialogue neophyte would need to venture into this provocative terrain of how we mean—a question general semanticists pose assiduously.
