The Power Of Positive Thinking Topics Norman Vincent Peale, Thinking, Affirmation, Mind The Power of Positive Thinking is a self-help book by Norman Vincent Peale, originally published in 1952. It proposes the method of "Positive Thinking". It basically aims at ensuring that the reader achieves a permanent constructive and optimistic attitude through constant positive influence of his conscious thought (e.g. by using affirmations or visualizations) and consequently achieves a higher satisfaction and quality of life. While early contributors in the positive thinking movement had built on theoretical justifications (like Phineas Parkhurst Quimby, Ralph Waldo Trine, Prentice Mulford), the The Power of Positive Thinking made more use of positive case histories and practical instructions.
