15862
|
Laws can come from data, from theory, from imagination and concepts, or from procedures
|
|
1
|
p.11
|
15864
|
Classification is just as important as laws in natural science
|
|
1
|
p.22
|
15865
|
Newton's First Law cannot be demonstrated experimentally, as that needs absence of external forces
|
|
1
|
p.34
|
15867
|
Laws describe abstract idealisations, not the actual mess of nature
|
|
1
|
p.35
|
15868
|
Idealisation idealises all of a thing's properties, but abstraction leaves some of them out
|
|
1
|
p.37
|
15869
|
Reports of experiments eliminate the experimenter, and present results as the behaviour of nature
|
|

p.39
|
15872
|
Must laws of nature be universal, or could they be local?
|
|
2
|
p.39
|
15870
|
Are laws of nature about events, or types and universals, or dispositions, or all three?
|
|
2
|

15871
|
Are laws about what has or might happen, or do they also cover all the possibilities?
|
|
2
|

|
15874
|
Scientific properties are not observed qualities, but the dispositions which create them
|
|
2

p.46
|
15875
|
In counterfactuals we keep substances constant, and imagine new situations for them
|
|

|
p.48
|
15876
|
Maybe laws of nature are just relations between properties?
|
|

|
p.59
|
15878

Some quantifiers, such as 'any', rule out any notion of order within their range
|
|

The Square of Opposition has two contradictory pairs, one contrary pair, and one sub-contrary pair
|
|

|
p.67
|
15880
|
In physical sciences particular observations are ordered, but in biology only the classes are ordered
|
|
3
|
p.75
|
15881
|
We can save laws from counter-instances by treating the latter as analytic definitions
|
|
3
|
p.78
|
15882
|
Since there are three different dimensions for generalising laws, no one system of logic can cover them
|
|
4
|
p.87
|
15884
|
Laws of nature remain the same through any conditions, if the underlying mechanisms are unchanged
|
|

|
15885
|

|
|

Science rests on the principle that nature is a hierarchy of natural kinds
|
|

|
'Grue' introduces a new causal hypothesis - that emeralds can change colour
|
|
5
|

|
15888
|
The grue problem shows that natural kinds are central to science
|
|
5
|

|
15889
|
It is because ravens are birds that their species and their colour might be connected
|
|
5
