− | The '''logic of relatives''', short for the '''logic of relative terms''', is the study of [[relation (mathematics)|relation]]s in their logical, philosophical, or [[semiotic]] aspects, as distinguished from, though closely coordinated with, their more properly formal, mathematical, or objective aspects. | + | The '''logic of relatives''', short for the '''logic of relative terms''', is the study of [[relation (mathematics)|relation]]s as represented in systems of signs by means of expressions known as ''rhemes'', ''rhemata'', or ''relative terms''. The treatment of relations by way of their corresponding relative terms affords a distinctive perspective on the subject, even though all angles of approach must ultimately converge on the same formal subject matter. |
| The consideration of ''[[relative term]]s'' has its roots in antiquity, but it entered a radically new phase of development with the work of [[Charles Sanders Peirce]], beginning with his paper [[Logic of Relatives (1870)|"Description of a Notation for the Logic of Relatives, Resulting from an Amplification of the Conceptions of Boole's Calculus of Logic" (1870)]]. | | The consideration of ''[[relative term]]s'' has its roots in antiquity, but it entered a radically new phase of development with the work of [[Charles Sanders Peirce]], beginning with his paper [[Logic of Relatives (1870)|"Description of a Notation for the Logic of Relatives, Resulting from an Amplification of the Conceptions of Boole's Calculus of Logic" (1870)]]. |
