The Power of Positive Thinking

While I was in Phnom Penh I was delighted by the presence of really quite good second-hand bookshops - something that is absent from Vietnam. As usual in such places, there was an eclectic collection of books - heavy on chick-lit and murder mysteries, and also a substantial number of business and self-help titles. For US$3 I bought this well-thumbed copy of the self-help classic The Power of Positive Thinking, and it travelled with me all through Cambodia and Vietnam.
I had never read it before, so was surprised to discover that it is extremely religious in content - Peale's main advice throughout the book is to read and memorise scripture and use quotes from the Gospels as positive affirmations. I can't imagine it appealing at all to modern day self-help readers, who are largely an unbelieving bunch, and those that are interested in spirituality tend to steer away from the old-fashioned style of 'memorise scripture' Christianity.
It would be unfair, however, to characterise Peale as some sort of fundamentalist Christian idealogue trying to propagate a religious agenda by stealth. He was, after all, an ordained minister, and a famous one at that. Kind of like the Benny Hinn of his time, only nicer and more substantial.
Peale had been born a Methodist, but became a famous clergyman with the Reform Church in America, which was very similar in theology and worldview. And while the religious advice he offers in this book is perfectly inoffensive and acceptable to almost any kind of Christian, his own personal beliefs were reasonably unconventional and progressive - influenced as they had been by the New Thought teachings of Charles Fillmore and Ernest Holmes, and incorporating a species of spiritualism influenced by his reading of Swedenborg.
So it's an odd book - I wouldn't even call it self-help, more a prayer manual and a practical guide to using the Bible. But if you find it in any bookshop (and it is still in print) it will almost certainly be filed under "Self-Help."
