Input (English): W. V. O. Quine's essay "Epistemology Naturalized" contrasts Hume's language theories with those of this philosopher, who emphasized the importance of paraphrasis, or contextual definition, and translating whole sentences containing abstract terms to show the meaning of the terms without identifying corresponding objects. In addition to that "theory of fictions", this philosopher distinguished between positive and negative acts and attacked theories of natural rights for relying on normative principles. His first book addressed Blackstone's Commentaries on the Laws of England, and another work by this philosopher contrasts social and hedonic calculations of the aggregate and individual forms of a quantity central to his "greatest happiness principle". FTP, name this philosopher who wrote A Fragment on Government and An Introduction to the Principles of Morals and Legislation, the founder of utilitarianism.
