In a posthumously published paper, Fr. W. Norris Clarke, S.J., declares that Thomistic personalism is the most creative and fruitful development in twenty-first century Thomism. I agree with Clarke, and I would also add that Thomistic personalism is the most creative and fruitful development in twenty-first centurymoral and political philosophy. Thus, in this paper—focusing on clarification and exhortation—I (i) identify the main commitments of personalism; (ii) identifyweak, moderate, and strong versions of Thomistic personalism; and (iii) suggest that Thomistic personalism is (...) a vocation for the twenty-first century that requirescollaboration between specialists from diverse backgrounds.

The thick-esse /thin-essence view asserts that esse—the act of existing—constitutes all of the ontological positivity, perfection, and intelligibility of a being, while essence is simply an internal limitation or mode of the esse of a being. In this paper I explain why Fr. W. Norris Clarke’s Thomistic personalism relies on the thick-esse /thin-essence view; acknowledge three objections to the thick-esse /thin-essence view; reply to these objections; and provide a positive argument for the thick-esse /thin-essence view. I conclude that Clarke’s reliance (...) on a thick-esse /thin-essence view does not militate against his Thomistic personalism; on the contrary, it militates in its favor. In order to reach this conclusion, though, I make it clear that the details of Clarke’s thick-esse /thin-essence view must be modified to fall in line with the details of William E. Carlo’s thick-esse /thin-essence view. (shrink)
