Suggestion (magazine)

Suggestion (1898-1906) was an American magazine of suggestive therapeutics and applied psychology published in Chicago at the turn of the twentieth century. It emerged from The Hypnotic Magazine and served as the principal publication associated with Dr. Herbert A. Parkyn and his Chicago School of Psychology.

It became a major influence on the New Thought movement by articulating a systematic, non-mystical framework for mind cure grounded in psychology, physiology, and clinical practice rather than religious doctrine. Through its consistent promotion of the "Law of Suggestion" as the governing principle behind mental influence, health, habit formation, and character development, Suggestion functioned as the primary source through which a medicalized understanding of mind cure circulated within New Thought. Its articles, terminology, and methods were widely echoed and reproduced in later journals, books, correspondence courses, and instructional systems created by graduates and affiliates of the Chicago School, extending the magazine’s influence well beyond its own publication run.
