Single Idea 8207

[filed under theme 2. Reason / B. Laws of Thought / 6. Ockham's Razor ]

Full Idea

It is the quest for system and simplicity that has kept driving the scientist to posit further entities as values of his variables. By positing molecules, Boyles' law of gases could be assimilated into a general theory of bodies in motion.

Gist of Idea

The quest for simplicity drove scientists to posit new entities, such as molecules in gases

A Reaction

Interesting that a desire for simplicity might lead to multiplications of entities. In fact, I presume molecules had been proposed elsewhere in science, and were adopted in gas-theory because they were thought to exist, not because simplicity is nice.


The 4 ideas from 'On Multiplying Entities'

Explaining events just by bodies can't explain two events identical in space-time [Quine]
Necessity could be just generalisation over classes, or (maybe) quantifying over possibilia [Quine]
The quest for simplicity drove scientists to posit new entities, such as molecules in gases [Quine]
In arithmetic, ratios, negatives, irrationals and imaginaries were created in order to generalise [Quine]
