Spirit's eternal or intelligence?

Debate with Van Hale on whether spirit of man is eternal or intelligence of this spirit is eternal. Misinterpretation of Joseph Smith's quote,“The Spirit of Man is not a created being; it existed from eternity and will exist to eternity.” BH Roberts, a Seventy, explained that he meant by "spirit" here "intelligence". Joseph Smith interchanged these words as BH Roberts explained in the Improvement Era 1907,"..misconceptions arise through a careless use of words, and through using words interchangeably.." and "did not aim at scientific exactness in the use of words." BH Roberts explained the difference between "spirits" and "intelligence" in the following: "The difference, then, between 'spirits' and intelligences," as here used, is this: Spirits are uncreated (eternal) intelligences inhabiting spiritual bodies (generated); while 'intelligences', pure and simple, are intelligent entities, but unembodied in either spirit bodies or bodies of flesh and bone. They are uncreated, self-existent entities;" Alma P. Burton who compiled "Discourses of the Prophet Joseph Smith" said the same thing "It is clear in this statement that the terms 'intelligence' and 'spirit' are used synonymously and that the intelligent uncreated entity, spoken of as intelligence, is meant." Also Joseph Smith said,"Is it logical to say that the intelligence of spirits is immortal, and yet that it has a beginning? The intelligence of spirits had no beginning, neither will it have an end."(HC 6:311) Futher, would Joseph Smith teach false doctrine that spirits are eternal when he obviously knew what it says in Hebrews: 6 And again, when he bringeth in the firstbegotten into the world, he saith, And let all the angels of God worship him. (Heb 1:6) 9 Furthermore we have had fathers of our flesh which corrected [us], and we gave [them] reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
