Nicholas Rescher

Ontology cannot be left to the natural sciences, if only because it deals also with hypothetical and fictional objects. It pivots about proto-categorical issues relating to the features of objects of any and all kinds. This brings into its range issues that test the limits of knowledge by asking questions that are inherently unanswerable (for example: “What is an instance of an occurrence that no one ever mentions?”). And it raises issues of norms and values that science (in its usual configuration) does not address.

Nature and Understanding explores the prospect of looking from a scientific point of view at such central ideas of traditional metaphysics as the simplicity of nature, its comprehensibility, or its systematic integrity. Rescher seeks to describe - in a way accessible to philosophers and nonphilosophers alike - the metaphysical situation that characterizes the process of inquiry in natural science. This is the culmination of many years of penetrating work in this area of philosophy by one of its most eminent exponents. It is the definitive presentation of some of Rescher's key ideas.

In _Error_, Nicholas Rescher presents a fresh analysis of the occurrence, causality, and consequences of error in human thought, action, and evaluation. Rescher maintains that error-avoidance and truth-achievement are distinct but equally important factors for rational inquiry, and that error is inherent in the human cognitive process (to err is human). He defines three main categories of error: cognitive (failure to realize truths); practical (failure related to the objective of an action); and axiological (failure in evaluation), and articulates the factors that contribute to each. His discussion also provides a historical perspective on the treatment of error in Greek philosophy, and by later thinkers such as Aquinas, Descartes, Spinoza, Leibniz, James, Royce, Moore, and Russell. _Error_ is an important reexamination of the significance of error to the fields of philosophical anthropology, epistemology, ontology, and theology. As Rescher’s study argues, truth and error are inexorably intertwined—one cannot exist without the other. Error is an unavoidable occurrence in the cognitive process—without missteps on the path to truth, truth itself cannot be attained. The risk of error is inherent in the quest for truth.

Nicholas Rescher examines the controversial social issue of the welfare state, and offers philosophical thoughts on the limits and liabilities of government and society. Questioning some of the principal assumptions of democratic theory and classical liberalism, Rescher theorizes that the current system is not a be-all end-all, but rather a necessity with limited scope that will ultimately fail to achieve its objectives. He further purports that the welfare state must be a transitional phase to a more affluent postindustrial society-a satisfying life, rather than an adequate one.

Luck touches us all. "Why me?" we complain when things go wrong—though seldom when things go right. But although luck has a firm hold on all our lives, we seldom reflect on it in a cogent, concerted way. In _Luck_, one of our most eminent philosophers offers a realistic view of the nature and operation of luck to help us come to sensible terms with life in a chaotic world. Differentiating luck from fate (inexorable destiny) and fortune (mere chance), Nicholas Rescher weaves a colorful tapestry of historical examples, from the use of lots in the Old and New Testaments to Thomas Gataker’s treatise of 1619 on the great English lottery of 1612, from casino gambling to playing the stock market. Because we are creatures of limited knowledge who do and must make decisions in the light of incomplete information, Rescher argues, we are inevitably at the mercy of luck. It behooves us to learn more about it.
