This is a clear, disciplined primer that bridges history and hands-on work with unusual grace. Horowitz frames the project with Jack Parsons’s call for simplicity, then actually delivers it: brisk chapters that define terms, sketch lineage, and move quickly into doable methods.
As usual for me, it is hard to fully warm to the praise of New Thought. I respect the lineage and its influence, yet I tend to prefer frameworks that place greater weight on ritual pressure and initiatory ordeal. Even so, Horowitz makes the New Thought inheritance feel less like cheerleading and more like a working hypothesis that you can test. He situates practice within an intelligent survey that runs from antiquity through Crowley and Spare, while nodding to psychical research and perceptual reality studies, then pulls everything back to pragmatic exercises that you can try tonight. That balance of sweep and utility is where the book quietly excels.
Stylistically, it is brisk and accessible without dumbing things down. The historical sketches are accurate to date and scope, the methods are modular enough to plug into a seasoned practice, and the tone stays results-oriented.
Bottom line: a strong four-and-a-half out of five. Even with my perennial reservations about New Thought enthusiasm, Practical Magick earns its space on the shelf.
