then the number of possible different correlative relations that reality logically can be placed in is incalculable, while self-identity is a concept that only correlates to non-self-identity.The question whether or not reality and self-identity actually do correlate to one another in a philosophically acceptable manner, still remains unsolved.Any doubt regarding the ontological status of the relationship between reality and self-identity places Hägerström’s use of these concepts as ontological standards in a completely different light than he wished himself.The apodictic certainty of the relationship between the two concepts is thus seriously undermined. However, in Selbstdarstellungen Hägerström identifies reality and self-identity with one another, rather than correlating them to one another, and he thus places them in a) a potentially apodictic relationship to one another, and b) on an equal footing with one another.188 In addition to Hägerström’s reduction of the number of entities (concepts) that can correlate to self-identity, Hägerström also takes a decisive step towards an overall application of the principle of parsimony, whose application is yet another typical characteristic of Hägerström’s philosophy. The second problemthat Konrad Marc-Wogau addresses concerns the concept determinateness.189 In Selbstdarstellungen Hägerström chooses to abandon the metaphysically tainted termSelbstidentität, which he used in Das Prinzip derWissenschaft, for the term Bestimmtheit (in other words “self-identity” is substituted for p a r t i 1 , c h a p t e r 3 94 3. 3. 3 “se lbst ident i tät” - dete rminatene s s : the metaphys ical connotat ions of the forme r 1929. For Hägerström’s discussion regarding the relationship between that which is real and reality see Hägerström, Selbstdarstellungen, pp. 9, 26-27, and 30. 188 Ibid., p. 18. Hägerström says that the two terms actually express the same thing, mean the same thing, denote the same thing and the terms must therefore be identical with regard to their denotation. 189 Marc-Wogau, Studier till Axel Hägerströms filosofi, pp. 57-59.
