Rudolf Lingens
fictional character created by the logician Gottlob Frege

Rudolph Lingens is a fictional character often used by contemporary analytic philosophers as a placeholder name in a hypothetical scenario which illustrates some feature of the indexicality of natural language. He was created by the logician Gottlob Frege in the course of one of the earliest systematic discussions of indexicals. A number of philosophers picking up on Frege's discussion of indexicals, notably John Perry, David Lewis, and Robert Stalnaker, have adopted Lingens to make their own points about indexicals.
De se attitudes
Lingens first appeared in Frege's influential essay 'Thought' ('Der Gedanke', published in Beiträge zur Philosophie des deutschen Idealismus I (1918–19), pp. 58–77). Mr. Lingens appears in the company of Leo Peter. Both are concerned with Dr. Gustav Lauben's having been wounded, and are later joined by Herbert Garner who is possessed of the knowledge that Gustav Lauben was born on 13 September 1875. Frege's discussion is concerned with how proper names and indexicals like 'I' function and how they are connected with the sense (or mode of presentation) that, on his account, each speaker who uses them associates with them.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Rudolf Lingens”, the useful work is to connect “fictional character created by the logician Gottlob Frege” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q7377245. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1918 and 1875.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation.
