Hugh Hefner began writing The Playboy Philosophy in 1962 at the beginning of the sexual revolution. Each chapter of The Playboy Philosophy was printed in an issue of the magazine beginning with the ninth anniversary issue in December 1962. The Playboy Philosophy continues each month in what is now The Playboy Forum.
From the introduction of the first chapter:
Recently, and increasingly in the past year, Playboy’s aims and outlook have been given considerable comment in the press, particularly in the journals of social, philosophical and religious opinion, and have become a popular topic of conversation at cocktail parties around the country. While we’ve been conscious of the virtues in seeing ourselves as others see us, we’ve also felt the image is occasionally distorted; having listened patiently for so long a time to what others have decided Playboy represents and stands for, we’ve decided — on this ninth anniversary — to state our own editorial credo here, and offer a few personal observations on our present-day society and Playboy’s part in it — an effort we hope to make interesting to friends and critics alike.
