    humble friend: what qualifies a “good thesis”?

    the masses are waiting anxiously for chapter 1! i had to fight through the queue this morning…

    Jelt, hi, I read your first chapter and I like it a lot. I’ll send you the doc with my comments. XXX, J

    Yo Jelt – I enjoyed reading the preface & first chapter, gives me some more context for the discussions we had in the Emerald City back in July. I wonder, though, about the statement on Line 118 (“Faced with a scarcity of data, the human mind reaches all too eagerly for secularism.”) – why the choice of the word ‘secularism’?
    I’m looking forward to reading Chapter 10!

    1. Jelte says:

      You are quite right in pointing out that ‘secularism’ is an awkward turn of phrase. I was attempting to be too playful – the sense of ‘secular’ in the chapter, and that used in Precambrian Geology, is that of: “Of or belonging to an age or long period” – but that does not go for ‘secularism’, which specifically refers to a doctrine. I’ve changed it.

    Dear Jelte- I read most all of the thesis, as soon as you left my room in Johnson Hall. The 8th chapter is NOT on line, although listed, so I do not have your conclusions as yet! Can you place them on line them for us???

    Your friend, CharlotPS the written words ring true- good go!!!!!
