Concept and object
In the philosophy of language, the distinction between concept and object is attributable to the German philosopher Gottlob Frege in 1892 (in his paper "Concept and Object"; German: "Über Begriff und Gegenstand"). == Overview == According to Frege, any sentence that expresses a singular thought consists of an expression (a proper name or a general term plus the definite article) that signifies an object together with a predicate (the copula "is", plus a general term accompanied by the indefinite article or an adjective) that signifies a concept.
