This volume asks how and why the concept of nature has changed its meaning in modernity and whether a rearticulation of premodern ideas about nature is possible. Building on the work of Voegelin, Strauss, Lonergan, Finnis, and others, the book compares and contrasts classical, medieval, and modern conceptions of nature.

Modern thought is sometimes presented as introducing a “turn to the subject” absent from ancient and medieval thought, although the schools of thought associated with Bernard Lonergan, Eric Voegelin, Leo Strauss, and the new natural law theory often find subjectivity already operative in the older forms. In this volume, sixteen leading scholars examine the turn to the subject in modern philosophy and consider its historical antecedents in ancient and medieval thought.

In this essay I argue that Thomas Aquinas is not as naively optimistic about the noetic effects of sin as is often portrayed by standard neo-Calvinist objections. Still, his metaphysics of the human person requires some development to better explain the mind’s impairment by sin, a development made possible by the work of Bernard Lonergan and the resulting Lonergan/Aquinas (L/A) model of the noetic effects of sin.

A critical evaluation of Deane-Peter Baker’s use of Charles Taylor to overcome perceived inadequacies in Reformed epistemology.
