Never before published in authentic form, this collection of Jeremy Bentham’s essays expands on his ideas about logic, language, ethics, and grammar.  Best known as the founder of the ethical theory of utilitarianism, Bentham’s philosophical contributions spanned political economy, judicial administration, prison reform, policing, religion, and many more fields. This new addition to The Collected Works of Jeremy Bentham deals with his ideas about logic, language, ethics, and grammar. Distributed across four essays written between 1814 and 1816 and an appendix, it includes discussions of methodization, ontology, real and fictitious entities, and propositions as the fundamental components of language. In addition to constituting a major contribution to the history of logic and language, this collection establishes the philosophical basis for classical utilitarianism and Chrestomathia , Bentham’s major work outlining his materialist theory of language.  Philip Schofield is director of the Bentham Project, Faculty of Laws, University College London, and general editor of the new authoritative edition of The Collected Works of Jeremy Bentham .
