In Deciphering Reality: Simulations, Tests, and Designs, Benjamin B. Olshin takes a problem-based approach to the question of the nature of reality. In a series of essays, the book examines the detection of computer simulations from the inside, wrestles with the problem of visual models of reality, explores Daoist conceptions of reality, and offers possible future directions for deciphering reality.

The ultimate goal of the book is to provide a more accessible approach, unlike highly complex philosophical works on metaphysics, which are inaccessible to non-academic readers, and overly abstract (and at times, highly speculative) popular works that offer a mélange of physics, philosophy, and consciousness.
