There are those who have attempted the topic before, to show the good or ill about artificially increasing a man's intelligence, and they have all fallen by the wayside, forgotten entries in the arena of literature, all because they forgot one factor: love.
In Flowers for Algernon, Keyes shows us a man who is jolted out of his comfortable world of stupidity and finds his friends who were not as good as he thought they were, that all he thought was nothing more than a veiled illusion. And he copes, as everyone must, he copes and finds love and comes to term with himself.
Just in time for him to realize that his intelligence is only temporary. In the most heart wrenching scenes of the novel, the reader must witness his intelligence fading rapidly, each journal entry a little less exact, the spelling a tiny bit worse, until the book comes full circle and he is back where he started from, only having a wisdom that he cannot understand, or comprehend.
Touching, moving, Flowers for Algernon is all that and more, it is an epic of emotion, an opera of getting what you want most and then realizing that you might have been better off.
