The mind-body dualism is an ancient concept that explores the relationship between mind and body as two distinct yet inseparable aspects of the self. In modern terminology, it is described as the interactive relationship between mind and body: the mind as an organizing pattern of thought and the physical body through which it operates. Iain McGilchrist's position is that the mind-body relationship is a complex system of interaction between physical, psychological, and social aspects. The truth of the mind-body state lies in recognizing its complementary natures: mind and body interact both internally and externally, constantly adjusting to their environment and to each other, creating a new, ever-changing reality. As such, the mind and body are inseparable and work together to form a complex integrated unity.
