We had a look at Aristotle's argument for the ontological primacy of substance in Metaphysics Z.1, and at the other kinds of primacy attributed there to substance. We considered in particular different interpretations of what it could mean that substance is primary in time, as it is claimed there. In addition, we went through 3 of the 4 different sense of 'in virtue of itself' (kath'hauto) distinguished in APo 1.4.
