Twentieth-century Catholic theology was strongly affected by Henri de Lubac's claim that the
western theological tradition went awry by allowing that one could have an adequate idea of
human nature without reference to humanity's supernatural end. According to de Lubac the
culprits were early modern scholastics and their mistake was the idea of pure nature.
Aquinas's Notion of Pure Nature and the Christian Integralism of Henri de Lubac: Not Everything
Is Grace contributes to the current literature criticizing de Lubac's thesis. Specifically it
offers an explanation for its enduring power and popularity with particular attention to the
contemporary Radical Orthodoxy movement.
