Single Idea 10579

[filed under theme 6. Mathematics / C. Sources of Mathematics / 9. Fictional Mathematics ]

Full Idea

Saying 'the number of Fs is 5', instead of using five quantifiers, puts the numeral in quantifiable position, which brings expressive advantages. 'There are more sheep in the field than cows' is an infinite disjunction, expressible in finite compass.

Gist of Idea

Putting numbers in quantifiable position (rather than many quantifiers) makes expression easier

A Reaction

See Hofweber with similar thoughts. This idea I take to be a key one in explaining many metaphysical confusions. The human mind just has a strong tendency to objectify properties, relations, qualities, categories etc. - for expression and for reasoning.


The 4 ideas from 'Abstract Objects: a Case Study'

Concrete objects have few essential properties, but properties of abstractions are mostly essential [Yablo]
We are thought to know concreta a posteriori, and many abstracta a priori [Yablo]
Putting numbers in quantifiable position (rather than many quantifiers) makes expression easier [Yablo]
Mathematics is both necessary and a priori because it really consists of logical truths [Yablo]
