Xperiment is a chapter book that features a boy named X who becomes involved with a group of children who struggle to find the meaning of justice in the small society that they have created for themselves. The kids explore the philosophical concepts of selective rule-breaking, thought-experimenting, and proposing alternative theories. The story introduces philosophies about human nature, civilization, and government by such philosophers as Plato, Aristotle, Rousseau, Locke, Hobbes, and Hume. Children are introduced to these concepts in an interesting and engaging way that makes them accessible and that highlights them as real-world issues.

This is a perfect-bound (glued) edition of this book, which has the advantage of a printed spine so that it can be found readily on a bookshelf. The book also comes in a saddle-stitched (stapled) edition. Additionally, there is an accompanying guidebook that serves both editions. (See below.)
