Florence Scovel Shinn (1871 to 1940) was an American artist and book illustrator who, in her middle years, reinvented herself as a New Thought spiritual teacher and metaphysical writer. That second act is the one posterity remembers: in New Thought circles she is best known for her first book, The Game of Life and How to Play It, published in 1925.
Her philosophy centred on the power of the word. As she framed it, invisible forces are forever at work in a person’s life, with each of us pulling the strings ourselves without knowing it, and whatever we give voice to, we begin to attract. Agree or not, it is an idea with a long reach, and listeners will recognise its echo in a great deal of self-help writing since.
