Essays on Logic, Ethics, and Universal Grammar
Philip Schofield (Editor)
This new volume of Bentham’s philosophical writings deals with his most fundamental ideas concerning logic, language, ethics and grammar. It includes four major essays written between 1814 and 1816, namely ‘Essay on Logic’, ‘Essay on Ethics’, ‘Didacologia’ and ‘Universal Grammar’, all of them closely related to Chrestomathia, Bentham’s major work on education.
In ‘Essay on Logic’, Bentham contrasts the præcognita of Aristotle with his own ‘characteristics’ of logic and deals with methodization, ontology, and the relationship between logic and language. In ‘Essay on Ethics’, he offers a critique of the Aristotelian virtues and outlines his own division of ethics into prudence, probity, and benevolence. In ‘Didacologia’, he presents an outline of a comprehensive plan for the division of the arts and sciences based on the method of exhaustive bifurcation and a new nomenclature. In ‘Universal Grammar’, Bentham deals with language as the basis for thought and communication and investigates the nature of the different parts of speech. The volume is completed with an Appendix containing fragmentary material, written in August and September 1813, with a focus on language. All the texts are based on Bentham’s original manuscripts and have never before been published in authentic form.
