Which expert from infinite jest best supports the inference that Hal is extremely intelligent?

"My applications not bought" I am telling them calling into the darkness of of the red cave that opens out before closed eyes

I believe the influence of Kierkegaard on Camus is underestimated. I believe Dennis Gabor may very well have been the Antichrist. I believe Hobbes is just Rousseau in a dark mirror

'I am not just a boy who plays tennis. I have an intricate history. Experiences and feelings. I'm complex.

My forehead is pressed into parquet I never knew could be so cold. I am arrested. I try to be perceived as limp and pliable. My face is mashed flat; Comp.'s weight makes it hard to breathe.

I believe the influence etc.

Explanation:

If you try to define what is (extremely) intelligent, you normally define intelligence by its intellectual range or wideness. That is, a person who knows everything about one thing I don't consider extremely intelligent but extremely specialised.

Of the four examples given here there is only one that enters profoundly into the fascinating world of the father of all sciences: philosophy. Kierkegaard is linked with Camus for its existentialism; Gabor, the Hungarian physist, is the Antichrist in the meaning of science versus faith (Christ); Hobbes, finaly has much in common with Rousseau but not with the fundamental part of obeying law (Rousseau: 'Everybody is equal for the law'; Hobson: everybody except the ruler).
