Johnson brings together a wide variety of his favorite themes in this brief book, as he follows a small band of travelers as they interact with the world around them.
"Rasselas" of the title is a prince who has led a sheltered life in the Happy Valley. Over time he becomes discontented with always being contented, and decides to escape his boredom by leaving. He is led by his guide Imlac, a court counselor and poet; accompanying them is Rasselas's sister and her maid.
Rasselas's goal is to make a "choice of life," something he has great difficulty doing once outside the confines of the Happy Valley. Repeatedly, the quartet encounters arguments and counterarguments for one way of life or another. Ultimately, they realize that it's not what they choose to do in this life that matters, as long as it doesn't impede on their after-life. That is the major conclusion they reach, in a final chapter which Johnson calls "The conclusion, in which nothing is concluded."
The book and its writing is fairly simple, and could be read by anyone in high school. Unlike a lot of Johnson's essays, the syntax is not tangled, and it is easy to get through. However, while the writing is fairly simple (Hemingway some times comes to my mind!), the themes are big. And a young reader must be patient: what sounds like a final opinion on one page frequently gets an "on the other hand" on the next.
This is important, because some of the lines which characters speak are easily taken out of context, and misintepreted. A reader who is not careful may find a line which seems to resonate, and draw the wrong conclusion. Here are two examples: at one point, Imlac (Rasselas's guide) says to Rasselas, "Human life is everywhere a condition in which there is much to be endured and little to be enjoyed." Pretty pessimistic! But in its proper context, Imlac has only cautioned Rasselas against envying the Europeans. In another instance, "The Artist" (no, not the one with the glyph!) tells Rasselas, "Nothing will ever be attempted, if all possible objections must be first oversome." How *wonderful* for the office bulletin board! But then (on the other hand) The Artist puts on a pair of man-made wings and takes a belly flop into a lake.
This book is chock full of aphorisims like these two, and that is part of its appeal. But they are deceptive in isolation, and should be considered as part of the book as a whole.
As a whole book, it is wonderful. Its scope is wide, because of the variety of experiences and because of the to-ing and fro-ing of the dialog. It's a great way to start with Johnson, because it has so many of his large themes, distilled into a little tale which really can fit in your coat pocket.
