THE AUTHOR
James Croall
Neurotherapist, systems thinker, and former Silicon Valley engineer. A lifetime of wondering what thoughts really are—and whether the language beneath them can be read.
The longer version.
For nearly thirty years, James worked in high-stakes technology — specializing in computer security and complex systems. That career trained him to think in terms of structure, signal, and failure modes: tracing invisible problems back to their source and designing systems capable of restoring coherence under pressure. Beginning in his mid-twenties, a parallel inquiry into consciousness, philosophy, and the nature of thought gradually became a sustained engagement with rationalist metaphysics and the philosophical foundations of mind.
That convergence became concrete when James turned toward neuroscience and neurotherapy — training as a certified QEEG technologist, working directly with brain data, and mapping patterns of attention, emotion, and regulation. Today he runs Peak Mind Neurotherapy in San Francisco. The Quantified Soul emerged from the synthesis of these worlds: decades of systems thinking and philosophical inquiry alongside hands-on clinical neuroscience. It is not a belief system or a self-help program. It asks to be tested, not adopted.
The conviction behind this work is simple: the quality of our thinking together depends on the quality of our thinking alone—and we have better tools for both than most people realize.
