Book excerpt: Nathan Coppedge virtually invented the discipline of logical exceptionalism known as exceptionism or typological exceptionism. This text is an intellectual triumph. As the seventh volume of the Dimensional Encyclopedia, it archetypally explores the concepts of coherence vs. incoherence and many related fields, while extending previously introduced concepts such as Coppedge's method of categorical deduction. It's subject is incoherence primarily. Instead of offering a unified theory, it offers eclectic insights about many types of exceptions.
