Introduction/Abstract Objects/Abstraction/Wright: Thesis: Sets as well as directions and numbers are to be introduced by abstraction.
Field: Example simple abstraction: is suitable for us saying that our talk of directions refers to parallelism. - But that does not quite work accordingly for numbers as it does for non-numeric talk (and "non-set theory").
Homomorphism/Field: (structure-preserving representation) is the bridge to find abstract counterparts to concrete statements ((s) observation statements) - Semantic Ascent/Abstract Counterparts: we would always obtain the results without them. - ((s) otherwise they would be something else.) - Field: we save a lot of time with this._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
