Richard Stallman is the philosopher king of software. He single-handedly ignited what has become a world-wide movement to create software that is Free, with a capital F. He has toiled for years at a project that many once considered a fool’s errand, and now that is widely seen as “inevitable.”
—Simon L. Garfinkel, computer science author and columnist
By his hugely successful efforts to establish the idea of “Free Software,” Stallman has made a massive contribution to the human condition. His contribution combines elements that have technical, social, political, and economic consequences.
— Gerald Jay Sussman, Matsushita Professor of Electrical Engineering, MIT
RMS is the leading philosopher of software. You may dislike some of his attitudes, but you cannot avoid his ideas. This slim volume will make those ideas readily accessible to those who are confused by the buzzwords of rampant commercialism. This book needs to be widely circulated and widely read.
—Peter Salus, computer science writer, book reviewer, and UNIX historian
