This edition of Leviathan is intended to provide the reader with a modestly abridged text that is straightforward and accessible, while preserving Hobbes' main lines of argument and of thought. It is meant for those who wish to focus primarily on the philosophical aspects of the work, apart from its stylish but often daunting early modern prose. The editors have updated language, style, punctuation, and grammar throughout. Very long, complicated sentences have been broken into two or more sentences for enhanced readability. In some instances, terms within a sentence are rearranged for enhanced clarity. Occasionally, an equivalent contemporary word is substituted for an archaic one. Ellipses indicate omissions of more than one sentence. Care has been taken to maintain the strength, nuance, and flavour of the work, especially of Hobbes' most difficult arguments. In addition, the volume offers a general Introduction and concise headnotes to each chapter. Annotation is geared to the student or novice reader. A glossary of key terms is also included, as well as an index.
