but he actually wrote a whole book about that definition and the attributes
he's just pointing out in that paragraph that one should not argue those points.

I'd be happy to oblige if it wasn't for the fact that these attributes are used by people who are trying to explain to me what their "god" is. And defining the undefined with incomprehensible attributes brings us no closer to the goal.
close to 90% of our speech/ideas are speculation, we dont know if guus is coming to juve but we also dont know if the sun is rising tomorrow. Obviously some are stronger that others as illustrated by the 2 examples mentioned, but the strength is relative to how much evidence supports it as with the sun rising tomorrow. Based on the evidence i have come across i have some idea of God's mercy but to go ahead and establish firm description and knowledge no one can.
