In 1986, David Rumelhart and James McClelland introduced Parallel Distributed Processing (PDP), a groundbreaking way of understanding how the mind works. Instead of viewing thinking as a series of logical steps, they proposed that mental processes arise from the simultaneous activity of many simple units, like the interconnected neurons in the brain, working together in harmony. This perspective transformed cognitive psychology by showing that learning, memory, and perception emerge through patterns of connections that strengthen with experience. Understanding PDP encourages us to see the mind not as a rigid machine, but as a flexible, adaptive network capable of growth and change, a powerful reminder that we, too, can rewire our thoughts and habits over time. On a personal level, this insight nurtures self-compassion and resilience, while on a societal scale, it fosters empathy and collaboration, recognising that just as neurons thrive in connection, so do people, communities, and cultures. The principle of harmonious interaction lies at the heart of Christianity, and is realised wherever believers dwell together in unity through a shared active dependency on Christ.
