He wants to be able to reconcile belief in the Church with his higher and more important commitments to science, rationality, and non-contradiction
Leaving aside the yawning abyss of problems this kind of statement excavates and brings to the surface, I've seen very little evidence, over the years, that Kevin has any real commitment to any of the above intellectual ideals. He uses them, or rather,
deploys them, for polemical purposes, across a narrow bandwidth of issues to which he has a deep emotional and psychological commitment, but I've seen no evidence that he values logic, rationality, critical thought, or "science" above or even equal to most of the apologists he regularly abuses.
The very idea that he thinks that a committed, faithful LDS, and especially one who defends the church upon intellectual grounds, must be, by the very fact of that commitment and faith, irrational, illogical, uneducated, stupid, and intellectually dishonest, is a clear indication that Kevin neither understands nor actually appreciates these qualities.
If he cannot or will not see them in others for whom similar intellectual ideals are matters of core principle, then I have severe doubts that he really understands what these qualities are and would actually recognize them in himself even if he possessed them to any substantial degree.
