"The major change through the prehistory of our species is the evolution of our brain, the development of a social organ that makes human culture (and language) part of our biology. My question is whether we can ever transcend the consequences and free ourselves of the biological limitations that have been imposed in the process."

"The main reason I have not sent you a question is that I can not think of one worth sending. So maybe my appropriate question is 'What question should I ask?' The one I wish I could identify would be of great intellectual or practical interest, and I (or someone) would have some hope of solving it. Peter Medawar once defined science as 'the art of the soluble'. This is an example of a definition that may be formally correct but does not help anyone trying to find out what science is, but it makes a good point. For a problem to be scientifically important it has to be soluble. How many angels can dance on a pinhead may be a problem of great interest to some people, but it is not soluble."

"It appears likely that the universe that we can observe is just one of an infinity of 'pocket universes,' which are continually being created by a process called eternal inflation. These pocket universes are believed to split off from a region of 'false vacuum', which expands so quickly that its volume increases forever, despite the loss of volume to the formation of pocket universes. The problem is to find a reliable way to extract predictions from this picture. The properties of the pocket universes can vary, and with an infinity of trials essentially anything will happen an infinite number of times. We need to learn how to distinguish the probable from the improbable, but so far such a probability calculation has never been given a precise definition."
