Existential Rationalism: Handling Hume's Fork | By Marcel Eschauzier

The original treatise introducing rational nondualism.

What if Western thought is warped by an illusion so persuasive that it affects almost every aspect of our understanding, including modern science? Scientists look for objective knowledge. But suppose the distinction between the observer and the observed does not exist. This insight—called nondual awareness—is deeply counterintuitive; few grasp its full implications. Yet rational thought points to a nondual world, as articulated in Existential Rationalism. The realization forces us to reexamine the foundations of modern science: Without an objective reality, what makes empirical evidence scientific?

This paradox takes us back to the 1700s when David Hume shook the foundations of rationalist philosophy with his compelling case for empiricism. Rationalism never fully recovered from his challenge. However, Eschauzier argues that nondual awareness is the missing piece to reinstate reason as the supreme scientific principle: Without an objective reality, reason justifies empirical science.

Thus revitalized, rational thought’s four foundational principles still offer trailblazing clarity today. From understanding the dualistic disposition in psychology to debunking the quantum computer mythology, Existential Rationalism charts a bold path forward, synthesizing ancient wisdom and modern science.
