James Chastek, Fourth Way, II

ST, I, 2, a. 3:
Quarta via sumitur ex gradibus qui in rebus inveniuntur. Invenitur enim in rebus aliquid magis et minus bonum, et verum, et nobile, et sic de aliis huiusmodi.

Is Aquinas then saying that goods are commensurable? How would he respond to the incommensurability thesis of the New Natural Law Theory? Does "good" need to be used univocally in order for such comparisons to be made? Or does it suffice that it is used analogically? (Dennis McInerny gives an answer in The Difficult Good.)
