I recommend the following: Henri Bergson, "Duration and Simultaneity, with Reference to Einstein's Theory" My youngest daughter has a fairly rare inborn metabolic disorder, resulting in impairment of the brain's sequencing function. In other words, she has no sense of "duration." Otherwise, quite bright, but the inability of the brain to sequence results in a loss of what we frequently refer to as "time," when "duration" is really the phenomenon. So, for instance, she cannot write in cursive, because that requires the ability to sequence. But, she can print, and type, and reads widely, and computers have been her salvation. Bergson explored this in several of his works, and over the years, as we (her parents) struggled to assist her, I read widely in this area. Provides a very helpful way to think about "time." peace, Ken --------------------------- Kenneth Frazier kennybod@xxxxxx kennybod@xxxxxxx
