Understanding Frege’s notion of presupposition

Abstract Why did Frege offer only proper names as examples of presupposition triggers? Some scholars claim that simply not care about the full range presuppositional phenomena. This paper argues, in contrast, he had good reasons for employing an extremely narrow notion ‘Voraussetzung’. On Frege’s view, many devices are now construed triggers either express several thoughts at once or merely ‘illuminate’ a thought particular way. Fregean presuppositions, essentially tied to names.
