Single Idea 16547

[filed under theme 26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism ]

Full Idea

It is not metaphysically necessary that water is composed of H2O molecules, because the natural laws governing the chemical behaviour of hydrogen and oxygen atoms could have been significantly different, so they might not have composed that substance.

Gist of Idea

H2O isn't necessary, because different laws of nature might affect how O and H combine

Source

Book Ref

-: 'Mind' [-], p.23


A Reaction

I fear this may be incoherent, as science. See Bird on why salt must dissolve in water. There can't (I suspect) be a law which keeps O and H the same, and yet makes them combine differently.

The reductionism found in scientific essentialism is mistaken [Oderberg]
Dispositional essentialism can't explain its key distinction between essential and non-essential properties [Psillos]
Can anything in science reveal the necessity of what it discovers? [Sidelle]
A major objection to real essences is the essentialising of social categories like race, caste and occupation [Gelman]
Defining an essence comes no where near giving a thing's nature [Almog]
Essences promise to reveal reality, but actually drive us away from it [Almog]
