Which work provides a clear introduction to Henri Bergson’s philosophical method?

The work that provides the clearest account of Henri Bergson’s philosophical method is his 1903 essay, An Introduction to Metaphysics.1

In this text, Bergson distinguishes between two fundamental ways of knowing. The first is an analytic, conceptual approach—often utilized in science—that tends to view reality as static, spatial, and discontinuous. The second is intuition, a global and immediate process that reaches the heart of a subject through sympathy. Bergson argued that while the analytical method is practical for acting upon the world, it fails to capture the essential reality of things because it ignores duration and perpetual flux. Consequently, his broader body of work serves as an exploration of this intuition, which he viewed as the innermost reality of all things.1
