Dune. So many thought-provoking quotes throughout the books, especially the first one. This one pops up in my head often, many years after having first read the book:

"Think you of the fact that a deaf person cannot hear. Then, what deafness may we not all possess? What senses do we lack that we cannot see and cannot hear another world all around us?"

Also Starship Troopers. Reading it made me somewhat regret not joining the military.

Feel the last part. This book changed the way I see Authority in general.

Herbert was a bit long-winded but man the world building was fantastic! We see it all the time nowadays, but when he wrote it, it was extraordinary (in the best sense).
