kaksisuuden
Kaksisuuden, also known as duality, is a concept that refers to the existence of two distinct but complementary aspects or elements within a single entity or phenomenon. This concept is prevalent in various fields, including philosophy, physics, and psychology. In philosophy, duality often refers to the coexistence of opposing ideas or principles, such as good and evil, or mind and body. In physics, it can describe the dual nature of particles, such as light, which exhibits both wave-like and particle-like properties. In psychology, duality can refer to the coexistence of conscious and unconscious processes, or the duality of self and other. The study of kaksisuuden has led to significant advancements in understanding the complexities of human experience and the natural world.
