A Reaction

This is support the idea that orders are a feature of reality, just as much as possible concatenation. Relational predicates, he says, refer to series rather than to individuals. Nice point.


The 8 ideas from 'Knowledge and the Philosophy of Number'

Numbers are properties, not sets (because numbers are magnitudes) [Hossack]
We can only mentally construct potential infinities, but maths needs actual infinities [Hossack]
Predicativism says only predicated sets exist [Hossack]
The iterative conception has to appropriate Replacement, to justify the ordinals [Hossack]
Limitation of Size justifies Replacement, but then has to appropriate Power Set [Hossack]
Transfinite ordinals are needed in proof theory, and for recursive functions and computability [Hossack]
'Before' and 'after' are not two relations, but one relation with two orders [Hossack]
The connective 'and' can have an order-sensitive meaning, as 'and then' [Hossack]
