Hi Fenton,
I do not find the approach phenomenologically compelling, or at least I no longer find that approach phenomenologically compelling. Being the father of two children and being intimately involved in their development over the last decade or so, part of which is allowing their experience of the world to affect mine in a intersubjectively rich way, there are lots of things I am certain about in regards to them. In particular I am certain about things which affect them emotionally, perhaps not apodictically certain - but if that is the demand then I think that the demand is too strong. That's just off the cuff. But really I have lots on and cannot contribute to this string for the next few weeks.

Philip
