This is a blog to discuss philosophy, chess, politics,
C. S. Lewis, or whatever it is that I'm in the mood to discuss.

The truth value of unprovable statements
Many statements which are not provable, at least not by us, are either true or false, and we agree that they are either true or false even if we have no way of determining whether they are true or false. A good example would be
1)______ committed the Jack the Ripper murders. For any name you put in, they either did or did not commit those crimes. Yet we have no doubt that there is someone (or more than one person) for which that statement is true, just as it is false of everyone else.
2) There is life of comparable intelligence to our own on other planets.
