Phineas P. Quimby
The New England clockmaker and mental healer usually placed at the headwaters of the New Thought tradition.
Quimby worked as a mesmerist before concluding that the healing he observed came from changed belief rather than from magnetism. He spent his later years treating patients in Portland, Maine, and recording his observations in notebooks that circulated privately for decades.
Those notebooks shaped the students who followed him, and most later New Thought writers trace at least part of their vocabulary back to his work.

The Quimby Manuscripts
“The trouble is in the mind, for the body is only the house for the mind to dwell in.”
— Phineas P. Quimby, The Quimby Manuscripts (published 1921)
Why this master matters
Nearly every teacher who follows in this collection is downstream of Quimby. He was the first American to argue, in plain working language, that what a person believes about their condition shapes the condition itself — and to test that claim patient by patient for years before writing a word of theory.
Ideas in practice
Understand the teaching.
01
Belief is an ingredient, not a bystander
Quimby watched patients improve when their explanation of their own condition changed. Notice the story you repeat about a problem; it is part of the problem's material.
02
Explain rather than impress
He refused to mystify his patients. The aim of a session was understanding, because understanding is what held once the practitioner left the room.
03
The mind wears grooves
Repeated fear settles into habit. Repeated clarity does the same, which is why he treated practice as more important than insight.

Historical context

Read it as historical writing on belief, attention and character rather than as medical, psychological or financial advice, and treat the biographical stories that grew up around these figures as tradition rather than documented fact.
