|Wessel I 346
Modality/Lorenzen/Wessel: it is assumed a certain group of people has accepted a certain system of statements W as true. From these people, all statements which follow logical from these statements are then recognized as true.
Lorenzen regards this as meaningful only for future statements.
Knowledge/Lorenzen/Wessel: for Lorenzen, it follows that everything we know is necessary with regard to this knowledge.
Tradition: For example, if we know that in a pea pod are five peas and that it contains protein. This is only the second necessary knowledge. According to Lorenzen, both statements are necessary knowledge. (WesselVsLorenzen).
Modality/WesselVsLorenzen: too broad a view. That all knowledge is supposed to be necessary is a "fatalistic consequence".
