The quest for simplicity drove scientists to posit new entities, such as molecules in gases [Quine]
|
|
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.

From:
Willard Quine (On Multiplying Entities [1974], p.262)
|
|
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.

In arithmetic, ratios, negatives, irrationals and imaginaries were created in order to generalise [Quine]
|
|
Full Idea:
In classical arithmetic, ratios were posited to make division generally applicable, negative numbers to make subtraction generally applicable, and irrationals and finally imaginaries to make exponentiation generally applicable.

From:
Willard Quine (On Multiplying Entities [1974], p.263)
|
|
A reaction:
This is part of Quine's proposal (c.f. Idea 8207) that entities have to be multiplied in order to produce simplicity. He is speculating. Maybe they are proposed because they are just obvious, and the generality is a nice side-effect.

Subjects may be unaware of their epistemic 'entitlements', unlike their 'justifications' [Burge]
|
|
Full Idea:
I call 'entitlement' (as opposed to justification) the epistemic rights or warrants that need not be understood by or even be accessible to the subject.
|
|
From:
Tyler Burge (Content Preservation [1993]), quoted by Paul Boghossian - Analyticity Reconsidered §III
|
|
A reaction:
I espouse a coherentism that has both internal and external components, and is mediated socially. In Burge's sense, animals will sometimes have 'entitlement'. I prefer, though, not to call this 'knowledge'. 'Entitled true belief' is good.
