When I hear theists and atheists pontificating on how they know God does or does not exist, I can only smile at the irrationality and, yes, vanity of the notion.

The study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself. Working on a motorcycle, working well, caring, is to become part of a process, to achieve an inner peace of mind. The motorcycle is primarily a mental phenomenon.

The irrationality of disgust suggests it is unreliable as a source of moral insight. There may be good arguments against gay marriage, partial-birth abortions and human cloning, but the fact that some people find such acts to be disgusting should carry no weight.

I don't know if the term 'liberation theology,' which can be interpreted in a very positive sense, will help us much.

We have all forgotten what we really are. All that we call common sense and rationality and practicality and positivism only means that for certain dead levels of our life we forget that we have forgotten.

Best not to look back. Best to believe there will be happily ever afters all the way around - and so there may be; who is to say there will not be such endings?
