Hermitix

Tertium Organum by P.D. Ouspensky (Book Review)

Feb 14, 2026
A brisk review of a metaphysical classic that tackles limits of the senses and the failings of strict empiricism. They explore Flatland-style analogies to explain higher dimensions and pitch time as a spatial fourth dimension. Panpsychism, evolution as growth in consciousness, and the idea that life taps higher-dimensional resources get attention. The conversation also considers a new logic beyond Aristotelian rules.
