This book introduces the thought of Giambattista Vico into the discussion about natural law. For many critics, natural law is not natural but a façade behind which lurks the supernatural - that is, revealed religion. While current notions of natural law are based on either Aristotelian/Thomistic principles or on Enlightenment rationalism, the book shows how Vico was the only natural law thinker to draw on the Roman legal tradition, rather than on Greek or Enlightenment philosophy. Specifically, the book addresses how Vico, drawing his inspiration from Roman history, incorporated both rhetoric and religion into a dynamic concept of natural law grounded in what he called the sensus communis: the entire repertoire of values, images, institutions, and even prejudices that a community takes for granted. Vico denied that natural law could ever furnish a definitive answer to moral problems in the social/public sphere. Rather he maintained that such problems had to be debated in the wider arena of the sensus communis. For Vico, as this book argues, natural law principles emerged from these debates; they did not resolve them.

Ong and Derrida are concerned with presence—for Ong the presence of the other; for Derrida the presence of the signified. These seemingly disparate epistemological meanings of 'presence' actually share some striking similarities, but differ about how reason should be figured, that is, what metaphors should be used to conceptualize reason. This disagreement is fundamentally about what Ong called 'analogues for intellect.' After describing the history of Ong's and Derrida's concept of presence, we indicate how the ethical and religious implications Ong and Derrida draw from 'presence' proceed logically from the analogues for intellect that each assumes. We will conclude, first, that these implications reveal a conflict of traditions—philosophy and rhetoric—but we also indicate how Ong's own rhetoric may permit dialogue between traditions.
