Is metaphysics possible? This book argues that the greatest threat to its viability derives from a self-destructive formalism. If what is essential to the nature of physical entities are the properties they have in common (as formalism holds), the inevitable result will be a reductionist collapse leaving only being or physical matter or some other underlying ground. In Essential Difference, James Blachowicz first constructs a one-to-one historical parallel between the modern crisis surrounding formalism (Hume/Kant/Hegel) and the ancient version (Parmenides/Plato/Aristotle), focusing on the principles of differentiation and individuation that underlie Aristotle s and Hegel s antireductionist programs. He then proposes a contemporary metaphysical theory of emergence in the context of recent philosophy of science. This theory, founded on the principle of the nonderivability of actual states from possible states, holds that the differences among physical, biological, and mental phenomena are essential to any metaphysics. Essential Difference is the only focused treatment of this problem and is itself essential for any understanding of the nature of metaphysics."

This book provides a framework that encompasses both physics and cognitive science - integrating them into a 'theory of everything' to establish a basis for both our scientific and humanistic endeavours. It explores the implications of brain laterality for understanding the emergence of mind and its relation to the physical world - arguing that the analytic vs. holistic cognitive differences of the left and right human cerebral hemispheres are key to understanding not only human self-consciousness and language, but also sociocultural phenomena ranging from the emergence of the scientific method and axes of political orientation to the direction of development of conceptions of God and the fundamental differences between polarizing philosophical traditions. In a further step, the book draws on the Darwinian principle that our cognitive apparatus is shaped by the environment in which it evolved to argue that human bilaterality mirrors the fundamental hylomorphic relation between formal organization and material components that constitutes physical nature itself. The logical division between holistic and analytic categories thereby offers a principled basis for a metaphilosophy.
