It appears to be his belief that Satan uses "logic and reasoning" to lead people out of the Church:
Thoughts?In these moments of trial, the adversary—who is always on the lookout—tries to use our logic and reasoning against us. He tries to convince us that it is useless to live the principles of the gospel. Please remember that the logic of the natural man “receiveth not the things of the Spirit of God: for they are foolishness unto him.” Remember that Satan “is an enemy [of] God, and [he] fighteth against him continually, and inviteth and enticeth [us] to sin, and to do that which is evil continually.” We must not allow him to deceive us; for when we do, we falter in our faith and lose the power to obtain God’s blessings.
