主题：【原创】闲话水浒之石碣受天文 -- 无斋主人

I think it really deserves to evaluate the reasonableness of the underlying rationale (including scope of evidence collecting) of the analyses and commentaries.

If a conclusion is pre-set and then evidences are collected merely based on this pre-set conclusion, the line of reasoning would be highly subjective and biased, and therefore would be weak or even erroneous.

Picking up evidences only based on one's needs to serve the pre-set conclusion is what I termed a problem of scope of evidence collecting.
