Evaluating Abhidhamma Errors Under Modern Neuro Psychology

Dr. Ruwan M Jayatunge

Abhidhamma literature began to develop around the third century BCE, though scholars debate whether its doctrines were taught by the Buddha himselfThe Abhidhamma’s accounts of physiology, cosmology, and psychology conflict with modern scientific evidence. For example, Abhidhamma commentaries identify the heart as the material basis of mind and consciousness, a view also held by Aristotle and other ancient traditions, possibly reflecting earlier Babylonian, Egyptian, or Greek ideas. Modern neuroscience, by contrast, links consciousness, perception, memory, and thought primarily to the brain and central nervous system. These parallels have led some scholars to suggest that Abhidhamma authors may have borrowed the cardiocentric theory from Greek philosophers. In addition, in the 3rd century BCE, early Indian medical traditions—later reflected in the Charaka and Susruta Samhitas—regarded the heart as the seat of life and consciousness and a conduit for mental energy. Abhidhamma commentators adopted this widely held medical view.

The Abhidhamma offers a detailed framework for classifying mental activity, though some of its claims may be viewed in modern psychology as philosophical rather than empirically verified. It describes cognition as a fixed sequence of 17 thought-moments, including stages such as determining and registering, whereas contemporary neuroscience portrays brain activity as distributed, parallel, and nonlinear. The Abhidhamma also distinguishes 89 or 121 types of consciousness and 52 mental factors, categorized as wholesome, unwholesome, or neutral. While this system can support contemplative inquiry, modern cognitive psychology typically understands emotion and cognition as fluid outcomes of interacting biological, psychological, and environmental processes.

The Abhidhamma locates consciousness in the heart-base (hadayavatthu), whereas modern neuroscience associates mental activity with the brain. It also presents mind (nama) and matter (rupa) as distinct realities, while neuroscience links mental processes to the activity of brain cells.

The Abhidhamma describes cognition as a sequence of rapid, discrete thought moments (cittas); neuroscience, by contrast, emphasizes extensive parallel processing across brain networks. Its account of mental traits and karma may suggest fixed pathways, while research on neuroplasticity shows that the brain changes with experience. Finally, the Abhidhamma identifies five physical senses and a separate mind-door, whereas neuroscience recognizes additional sensory systems, including balance, proprioception, and interoception.

The Abhidhamma’s descriptions of physiology, cosmology, and psychology conflict with modern scientific evidence. Rather than being divinely revealed or produced by superhuman beings, it was developed by one or more early Indian scholars. Its teachings reflect the ancient worldview of the time, which treated mind (nāma) and matter (rūpa) as fundamentally distinct rather than understanding the mind as a product of the evolved brain.
