A Teacher
Mitch Horowitz
The serious historical chronicle of positive-thinking and occult America
The transmission
Mitch Horowitz (born November 23, 1965) is an American historian, writer, lecturer, and former editor-in-chief of the Penguin imprint TarcherPerigee, where he worked for years inside the publishing house that carried much of the modern self-help and metaphysical canon.
Raised in Queens and on Long Island, he took a degree in English literature from Stony Brook University and worked as a reporter before turning to the documentary history of America’s alternative spiritual movements.
He identifies openly as a “believing historian,” having participated in many of the currents he studies, including Theosophy, New Thought, Transcendental Meditation, and the Gurdjieff Work, while still holding himself to standards of evidence and sourcing.
His best-known books are Occult America: The Secret History of How Mysticism Shaped Our Nation (2009), which won the 2010 PEN Oakland/Josephine Miles Award; One Simple Idea: How Positive Thinking Reshaped Modern Life (2014), a critical history of the positive-thinking tradition from Quimby through Peale and beyond; The Miracle Club: How Thoughts Become Reality (2018); and Modern Occultism (2023).
Within the Atlas of Mind-Power he occupies a distinct role: not a teacher advancing a method but the field’s serious chronicler, the writer who has done the most to give New Thought, mind-power, and American occulture a documented, dates-and-sources history rather than a promotional one.
What they gave
Documentary history of positive thinking: One Simple Idea traces the lineage of mind-power from Quimby and New Thought through Christian Science, Peale, and the self-help industry, treating it as a genuine cultural force.
- Legitimizing occult America as a subject: Occult America placed Spiritualism, Theosophy, and metaphysical religion inside mainstream American history rather than the margins.
- The “believing historian” stance: Models a sympathetic-but-evidential approach, taking practitioners’ claims seriously while documenting them honestly.
- Bridging scholarship and practice: As an editor and author he connected academic religious history with the living self-help readership, giving the tradition a credible chronicler.
In their words
The principle of positive thinking is simplicity itself. Picture an outcome, dwell on it in your thoughts and feelings, and unseen agencies — whether metaphysical or psychological — will supposedly come to your aid. Seen in this way, the mind is a causative force.

Influenced by: the New Thought tradition; American Spiritualism and occultism; Theosophy; the positive-thinking lineage from Quimby to Norman Vincent Peale; academic religious history.
