Heretics of Dune by Frank Herbert

Until the last chapter, Frank Herbert's "Heretics of Dune" initially seems like a mishmash of estranged plot developments and characters that contribute nothing to the book. While it took me some serious willpower to complete the book, once everything was pulled together in its conclusion, I saw "Heretics of Dune" for what it is: a novel promoting free choice and the pursuit of our personal "noble purposes." For these themes alone, and the fact that every action taken in the book was aimed toward one purpose, "Heretics of Dune" is one of Herbert's greatest accomplishments in his Dune Chronicles.

I have read only two Dune books- 'Heretics of Dune' and 'Chapter House Dune'.  But I like 'Heretics of Dune' best because there is one subject that interests me- the potential of the human brain.  The Duncan Idaho ghola (ressurected by the Tleilaxu and purchased by the Bene Gesserit) and the Bashar Miles Teg are the best example.  Simply by thinking, they solve many problems by applying what they synthesized in their mind.  Mr Herbert was aware of the human mind powers and he masterfully induced that in two of these great characters which I adored in this novel.

The Dune novels drive me to think and thinking is a hard process.  Most people don't think that hard but the characters of Dune (though fictional) demonstrate the importance of thinking especially putting matters to rest.
