Mental Mechanisms, Reductionism, and the Architecture of Mind–Brain Explanation: An Integrative Philosophical and Neuroscientific Analysis
Issue Vol. 2 No. 02 (2025): Volume 02 Issue 02 --- Section Articles
Abstract
The relationship between mind and brain remains one of the most enduring and contested issues in philosophy, neuroscience, and the biomedical sciences. Over the past century, increasingly sophisticated neuroscientific methods have transformed our understanding of neural structure and function, intensifying debates about reductionism, mechanistic explanation, and the ontological status of mental phenomena. This article offers a comprehensive and integrative analysis of mind–brain explanation by critically examining reductionist strategies, mechanistic models, and emergentist critiques as articulated in key philosophical and neuroscientific literature. Drawing on foundational work in logical positivism, psychoneural reduction, mechanistic explanation, and systems neuroscience, the paper explores how mental mechanisms are discovered, decomposed, localized, and interpreted within contemporary science. Particular attention is given to the neuron doctrine, molecular and cellular reductionism, and the role of higher-level cognitive and social explanations that resist simple neural identification. By engaging deeply with arguments from Bechtel, Bickle, Carnap, Anderson, Dennett, and others, the article demonstrates that while reductionist approaches have yielded powerful explanatory tools, they remain incomplete without an appreciation of organizational complexity, context sensitivity, and multi-level causation. The analysis further incorporates clinical perspectives on mental disorder, challenging the assumption that psychiatric phenomena can be exhaustively explained as brain disorders alone. The article concludes that a pluralistic, mechanistically informed, and non-eliminative framework offers the most promising path forward for understanding the mind–brain relationship, preserving scientific rigor while respecting the complexity of mental life.
