Nancy Cartwright on Bridge Laws - Dictionary of Arguments

I 15
CartwrightVsBridge Laws: this is too simple a view of how explanations work; we must first provide a description of the situation before we can figure out the mathematical requirements of the theory.
>Description
, >Facts, >Situations, >Experiments.
I 132
Bridge Principles/BP/Cartwright: Tradition (Hempel, Grünbaum, Ernest Nagel): the propositions of a theory consist of two types:
a) internal principles: content of the theory, laws about the behavior of the objects
b) bridge principles: connect the theory with more accessible aspects of reality (> "prepared description")
Early: connection with monitoring reports. >Observation, >Theory ladenness.
Vs: that does not work because of the theory ladenness of the observation new: connection of the the theory with already understood vocabulary. >Vocabulary, >Observation language, >Theoretical terms.
Hempel/late: (1979)(1) this kind of explanation is not really deductive - HempelVsBridge-Principles: Problem: not invariably valid.
I 135
Bridge principle: saying which equations are to be chosen - (how we get into the mathematical language and out of it again).
I 205
CartwrightVsBridge Principles: instead of it we need insights on which operator is the right one for each problem. ((s) Operators/Cartwright/(s): represent the energies that are relevant in a situation within the equations.)
