Tracing inference backwards closes in on a small set of axioms and postulates [Frege]
The essence of mathematics is the kernel of primitive truths on which it rests [Frege]
Axioms are truths which cannot be doubted, and for which no proof is needed [Frege]
A truth can be an axiom in one system and not in another [Frege]

To create order in mathematics we need a full system, guided by patterns of inference [Frege]

Scholastics treat relations as two separate predicates of the relata [Cover/O'Leary-Hawthorne]

We can ask for the nature of substance, about type of substance, and about individual substances [Cover/O'Leary-Hawthorne]

The general assumption is that substances cannot possibly be non-substances [Cover/O'Leary-Hawthorne]

The unmoved mover and the soul show Aristotelian form as the ultimate mereological atom [Aristotle, by Koslicki]
