These principles are tools. Hand them to someone who has never heard of Hermeticism and say: assume these are true. What do they predict? The predictions are the test.
Mentalism says consciousness is the ground of reality. Run that against the Hard Problem and it dissolves: you stop trying to get subjective experience from objective matter, because matter was always a pattern in mind. Run it against quantum mechanics and the observer effect becomes structural rather than paradoxical. Every night your mind builds complete realities from nothing. Placebos produce measurable physiological changes. Wheeler’s delayed-choice experiments show measurement choices made now affecting what patterns can be extracted from a particle’s earlier behavior. Mentalism predicts all of this. Materialism explains none of it.
Correspondence says patterns repeat at every scale. Neurons mirror river deltas mirror the cosmic web. Phi governs spiral galaxies, DNA, and flower petals with identical mathematics. Run it against the parasitology data and it predicts what the traditions report: entities that rewrite host behavior at the biological level repeat at the institutional and metaphysical levels. If a pattern holds at two scales, it should hold at a third. When it does, you’re looking at structural law.
Vibration says everything moves, everything oscillates, everything has a frequency signature. String theory arrives at the same claim: reality consists of vibrating strings, different vibrations producing different particles. Every contemplative tradition uses sound as primary technology: chanting, singing bowls, breathwork, mantra. They’re tuning the instrument. What we call matter is frequency slowed to perceptibility. What we call spirit is frequency accelerated beyond normal perception. Same substance, different octaves.
Rhythm says everything flows in and out, everything has its tides. Run that against history and cyclical time falls out: the Yugas, the Shmita cycles, the precession ages, the Fourth Turning. The untrained person is crushed by the downswing. The trained person recognizes half a cycle and positions for the return. Whoever controls the clock controls the narrative, because the eternal present of social media prevents the pattern recognition that would reveal the cycle.
Cause and Effect says nothing happens by chance. What looks like coincidence is causation operating at a level the observer can’t see. Run that against synchronicity and it becomes data rather than noise. Run it against the monument network and you find precision that chance cannot produce. Every broadcast has a source. Every effect traces to a cause. The question is always: what plane is the cause operating from?
Gender says every creative act requires the union of projective and receptive forces. Consciousness and will, receptive and directive, feminine and masculine in the creative rather than biological sense. Run it against alchemy and you find the sacred marriage. Run it against practice and you find why pure aggression and pure passivity both fail. Sophia and Christos, Shiva and Shakti, Prakriti and Purusha. Every tradition that mapped the creative process arrived at the same two-pole architecture.
The principles generate predictions. The predictions match the evidence. That’s what investigative tools do.
