Single Idea 9575
[filed under theme 15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
]
Full Idea
Husserl identifies a 'unitary mental act' where several contents are connected or related to one another, and also a difference-relation where two contents are related to one another by a negative judgement.
Gist of Idea
Husserl identifies a positive mental act of unification, and a negative mental act for differences
Source
report of Edmund Husserl (Philosophy of Arithmetic [1894], p.73-74) by Gottlob Frege - Review of Husserl's 'Phil of Arithmetic' p.322
Book Ref
-: 'Mind July 1972' [-], p.322
A Reaction
Frege is setting this up ready for a fairly vicious attack. Where Hume has a faculty for spotting resemblances, it is not implausible that we should also be hard-wired to spot differences. 'You look different; have you changed your hair style?'
