The principle of proportionate causality is often cited as a cause for concern that Thomistic metaphysics may be irreconcilable with a theory of biological evolution. St. Thomas does hold that for the generation of what he calls perfect animals, a generator of the same species is required. This study clarifies what the proportionate causes of generated organisms are for Thomas, examining his views about spontaneous generation, reproductive generation, and hybridization, while also articulating the roles of both the heavenly bodies and their separate movers as universal causes of generation. This study establishes that Thomas's assertion of the need for a univocal generator for perfect animals is grounded not in the principle of proportionate causality, but rather in physical and biological doctrines received from Aristotle and in a causal principle that seems reconcilable with biological evolution, namely, that a remote universal cause requires more mediating causes to produce more powerful effects.

Interpreters of Aquinas tend to posit a seamless transition from knowledge of the transcendentals in the abstract to naming God as one, true, and good. Some even suggest that the convertibility of the transcendentals with being implies the unity, truth, and goodness of esse divinum. Others hold simply that the meaning and order of these divine names is founded upon the meaning of the transcendentals. This study: (1) explains why Aquinas avoids " transcendental arguments " for these divine names; (2) argues that truth and goodness, as divine names, are derived not only from the transcendental meanings of these terms but also from specific perfections, namely, truth of intellect and moral goodness; (3) shows that the order of these divine names in the two Summae (being, good, one, true) better reflects the order of the transcendentals as received perfections than their more familiar order in the abstract (being, one, true, good).
