I didn't use the word 'dim' so I don't know why you put that in quote marks. Nor indeed why you implied the treatise was Henry's own work, and tried to pass off the 'defender of the faith' title as a reward for scholarship rather than a favour for support. If you have read all that before you don't appear to have taken it in. 
Henry's obsession with Anne Boleyn was as much infatuation with her as the need for an heir. After Catherine of Aragon it's only Anne B and Jane Seymour where an heir was a primary focus, because Jane brought him Edward. While it is true he could have done with a spare, he married Anne of Cleves for diplomatic reasons, without having met her, and she claimed the marriage was not consummated; Catherine Howard he fell in love with and married despite the (probably true) rumours of previous lovers; and in Catherine Parr he needed a nurse.
The pursuit of an heir is a rationalisation of the actions of a man who was no more in control of his love life than he was his eating or gambling.
His marital strategies or lack thereof were as disastrous as his foreign policy and those are the only policies he can be held to be personally responsible for.
I can't argue with how you choose to define intelligence, but, by my standards, he was not an intelligent man.
