The Golden Rule has received remarkably little philosophical discussion. No book has ever been written on it, and articles devoted to it have been exceedingly few, and usually not very searching. It is usually mentioned, where it is mentioned at all, only in passing, and most of these passing remarks have either been false, trite, or misleading, though some of them, as we shall see, have certainly been interesting enough. Considering its obvious importance and its almost universal acceptance, this dearth (...) of philosophical discussion is unfortunate, and also somewhat surprising. One of the things I hope to show about it, though only incidentally, is that there are problems connected with it of the utmost subtlety, worthy of the attention of even the most minute philosophers.
