He has a worried, subdued personality, warning others of dangers and trying to reduce their enthusiasm (see his reactions to Pergrin and Merry; both Ti/Fe valuing extroverts). An ENTj would have been almost the complete opposite to this.
I really don't agree with this at all. The idea that positive and negative feelings/attitude are predestined through type is ridiculous.
Feelings and moods are a reflection of a number of factors, all that can change, and have nothing to do with Socionics

Actually the fact that he is an archetypal intellectual (wizard even, supposedly an art that requires decades of study) strongly indicates INTj over ISTj even to the point of making the latter look wholly implausible.
You think he was Se PoLR?

The only reasonable alternatives to INTp are ISTp and INFp.
If I may ask, why?

From reading the book, I mentioned above, that compile his personal letters, containing his views, Se+Ni valuing and Ne+Si devaluing is highly unlikely.
Some of the topics he frequently discusses are about his dislike of industrialization, modernization, unethical behavior and force/control (particularly politically)
