Object of thought/intentional identity/Gärdenfors: example by Peter Geach (1967): the three farmers Cob, Hob and Nob believe that a witch is bothering them, and they wonder if she is the same witch who has done different things. Problem: since there is no witch, there is only one object of thought. Question: is it the same object that the three farmers think of? See also Edelberg (2006) and Jacot (2012).
Prototype/Jacot/Gärdenfors: "a witch" is under-determined. Solution: Prototypes.
Fixed point/Gärdenfors: is reached, if e.g. one refers to the with with index words and pronomina. However, this fixed point is fragile, which becomes apparent when additional properties are added that are possibly incompatible.
Solution: if there is a "meeting of minds", the same conclusions should be drawn.
Gärdenfors: such a theory can be called sociocognitive._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
