Here's my perspective on why Jesus said that blasphemy against the Holy Spirit will never be forgiven:
I'm reminded of the second part of Romans 1, in which Paul wrote that mankind has no excuse for not believing (and even denying) that God exists (because the creation plainly bears that out). I believe that the Holy Spirit is the One who gives people the awareness of the existence of God. Therefore, to suppress and reject that awareness is to possibly place oneself outside of salvation, at least for a time.
That being said, it can't be denied that the scribes & Pharisees of Jesus' day believed that God exists. It's just that most of them couldn't fathom or entertain the idea of God taking the form of a Man; hence why they thought that Jesus performed His miracles by the power of Satan.
I think that their attribution of His miracles to Satan was a manifestation of their rejection of the Spirit. The Spirit also prompts people to accept & believe that Jesus is God and to receive Him as their Savior and Lord. And those who rebel against the Spirit's promptings, whether Jew or Gentile, will not be forgiven for their sins because they will have not received Christ as Savior.
So, it's kind of a three-step process:
1. The Spirit convinces people that God exists through evidence in the creation
2. The Spirit convinces people that Christ Jesus is part of the Godhead
3. Those who accept Christ as Savior and Lord are indwelt by the Spirit.

Romans 2:13-15
King James Version
13 (For not the hearers of the law [are] just before God, but the doers of the law shall be justified.
14 For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
15 Which shew the work of the law written in their hearts, their conscience also bearing witness, and [their] thoughts the mean while accusing or else excusing one another
