Now, the method of Buddhism, and this is absolutely important to remember, is dialectic. That is to say, it doesn't teach a doctrine. You cannot find out anywhere what Buddhism teaches, as you can find out what Christianity or Judaism or Islam teaches. Because all Buddhism is a discourse, and what most people suppose to be its teachings are only the opening stages of the dialog.
--Alan Watts
"Faith" is more and more being used a synonym for "religion." This works fairly well for those three religions of Middle Eastern origin, but not very well at all for many other religions. Not all make a virtue of believing something for which there is insufficient evidence. Not all have a absolute truth to have faith in. This very parochial linguistic practice makes it even more difficult for us to make sense of unfamiliar religions. And it drives me nuts.
