Max Wertheimer (1880–1943), Kurt Koffka (1886–1941), and Wolfgang Köhler (1887–1967) were the visionary founders of Gestalt psychology, a revolutionary movement in the early 20th century that transformed how we understand human perception, learning, and consciousness. At a time when psychology was dominated by reductionist approaches, these three thinkers championed the profound idea that "the whole is greater than the sum of its parts." Wertheimer's seminal 1912 work on the phi phenomenon laid the foundation for understanding how we perceive motion and patterns holistically. Koffka extended Gestalt principles to child development and education, emphasising the importance of meaningful learning, while Köhler’s insightful experiments with chimpanzees in the 1920s revealed the power of insight and problem-solving beyond trial-and-error. Their collective contributions offer more than theoretical insight. They promote a worldview that honours wholeness, coherence, and meaning, which remains vital today for personal wellbeing, mental health, and societal harmony. By encouraging us to see connections rather than fragments, Gestalt psychology fosters self-awareness, empathy, and more integrated ways of living. There is a certain irony in the fact that this is a lesson for psychology itself. A psychology that claims to reflect the whole of human personhood must recognise the spiritual dimension of experience and behaviour. When God is not merely acknowledged, but received through faith in Jesus Christ, individuals are spiritually transformed and empowered to proceed towards increased renewal, integration, and wellbeing.
