The 5 ideas from 'Plural Quantification Exposed'

Can second-order logic be ontologically first-order, with all the benefits of second-order? [Linnebo]
A comprehension axiom is 'predicative' if the formula has no bound second-order variables [Linnebo]
A 'pure logic' must be ontologically innocent, universal, and without presuppositions [Linnebo]
The modern concept of an object is rooted in quantificational logic [Linnebo]
Plural quantification depends too heavily on combinatorial and set-theoretic considerations [Linnebo]
