I haven't read it. Does he give a logically defensible and coherent account of "agnosticism" that would distinguish it from a logically defensible and coherent account of "atheism." If so, would you care to summarize?
I'm not sure about "logically defensible", but here are Dawkins' levels:
1.
Strong Theist - 100% probability of God (I know there is a God!)
2.
De facto Theist - Very high, but < 100% probability of God
3.
Technically agnostic- leaning towards theism, higher than 50% probability of God
4.
Impartial agnostic - exactly 50% probability of God
5.
Technically atheist - leaning towards atheism, less than 50% probability of God
6.
De facto atheist - Very low, but > 0% probability of God
7.
Strong atheist - 0% probability of God (I know there is no God!)
Dawkins argues most people you would consider an atheist are actually De facto atheists (6) - it is probably the highest a skeptic would or should consider but (7) was included with (1) for symmetry. However, there seem to be quite a few people that do fall into (1).
Now, with these categories, can you say any are logically defensible? Based on evidence, I personally consider 6 to be really the only logically defensible position.
But that's just me
