Single Idea 6616

[filed under theme 26. Natural Theory / D. Laws of Nature / 2. Types of Laws ]

Full Idea

The principle of least action is not a causal law, but is what I call a 'global law', which describes the essence of the global kind, which every object in the universe necessarily instantiates.

Gist of Idea

Least action is not a causal law, but a 'global law', describing a global essence

A Reaction

As a fan of essentialism I find this persuasive. If I inherit part of my essence from being a mammal, I inherit other parts of my essence from being an object, and all objects would share that essence, so it would look like a 'law' for all objects.


The 11 ideas with the same theme [possibility divisions of laws of nature into types]:

Seven theories in science: mechanics, heat, electricity, quantum, particles, relativity, life [Heisenberg, by PG]
Some laws are causal (Ohm's Law), but others are conceptual principles (conservation of energy) [Wright,GHv]
Oaken conditional laws, Iron universal laws, and Steel necessary laws [Armstrong, by PG]
Least action is not a causal law, but a 'global law', describing a global essence [Ellis]
Laws can come from data, from theory, from imagination and concepts, or from procedures [Harré]
Are laws of nature about events, or types and universals, or dispositions, or all three? [Harré]
Are laws about what has or might happen, or do they also cover all the possibilities? [Harré]
Laws are either 'strict', or they involve a 'ceteris paribus' clause [Kim]
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]
Laws are either disposition regularities, or relations between properties [Bird]
