Single Idea 16179

[filed under theme 26. Natural Theory / D. Laws of Nature / 4. Regularities / b. Best system theory ]

Full Idea

There is no reason to think that the principles that best organise will be true, nor that the principles that are true will organise much.

Gist of Idea

Good organisation may not be true, and the truth may not organise very much

A Reaction

This is aimed at the Mill-Ramsey-Lewis account of laws, as axiomatisations of the observed patterns in nature.


The 18 ideas from Nancy Cartwright

Theories can never represent accurately, because their components are abstract [Cartwright,N, by Portides]
There are fundamental explanatory laws (false!), and phenomenological laws (regularities) [Cartwright,N, by Bird]
Laws of appearances are 'phenomenological'; laws of reality are 'theoretical' [Cartwright,N]
To get from facts to equations, we need a prepared descriptions suited to mathematics [Cartwright,N]
The covering law view assumes that each phenomenon has a 'right' explanation [Cartwright,N]
Laws get the facts wrong, and explanation rests on improvements and qualifications of laws [Cartwright,N]
Laws apply to separate domains, but real explanations apply to intersecting domains [Cartwright,N]
A cause won't increase the effect frequency if other causes keep interfering [Cartwright,N]
Covering-law explanation lets us explain storms by falling barometers [Cartwright,N]
I disagree with the covering-law view that there is a law to cover every single case [Cartwright,N]
There are few laws for when one theory meets another [Cartwright,N]
Good organisation may not be true, and the truth may not organise very much [Cartwright,N]
You can't explain one quail's behaviour by just saying that all quails do it [Cartwright,N]
Simple laws have quite different outcomes when they act in combinations [Cartwright,N]
Two main types of explanation are by causes, or by citing a theoretical framework [Cartwright,N]
In science, best explanations have regularly turned out to be false [Cartwright,N]
An explanation is a model that fits a theory and predicts the phenomenological laws [Cartwright,N]
Causality indicates which properties are real [Cartwright,N]
