This novel approach to epistemological discourse explains the complex but crucial role that systematization plays-not just for the organization of what we know, but also for its validation. Cognitive Harmony argues for a new conception of the process philosophers generally call induction.
Relying on the root definition of harmony, a coherent unification of component parts (systemic integrity) in such a way that the final object can successfully accomplish what it was meant to do (evaluative positivity), Rescher discusses the role of harmony in cognitive contexts, the history of cognitive harmony, and the various features it has in producing human knowledge. The book ends on the issue of philosophy and the sort of harmony required of philosophical systems.
Nicholas Rescher tackles the major questions of philosophical inquiry, pondering the nature of truth and existence. In the authoritative voice and calculated manner that we’ve come to expect from this distinguished philosopher, Rescher argues that the development of knowledge is a practice, pursued by humans because we have a need for its products. This pragmatic approach satisfies our innate urge as humans to make sense of our surroundings.
Taking his discussion down to the level of particular details, and addressing such topics as inductive validation, hypostatization fallacies, and counterfactual reasoning, Rescher abandons abstract generalities in favor of concrete specifics. For example, philosophers usually insist that to reason logically from a counterfactual, we must imagine a possible world in which the statement is fact. But Rescher argues that there’s no need to attempt to accept the facts of a world outside our cognition in order to reason from them. He shows us how we can use our own natural system of prioritizing, our own understanding of the fundamental, to resolve the inconsistencies in such statements as, “If the Eiffel Tower were in Manhattan, then it would be in New York State.”
In using dozens of real-world examples such as these, and in arguing in his characteristically succinct style, Rescher casts light on a wide variety of concrete issues in the classical theory of knowledge, and reassures us along the way that the inherent limitations on our knowledge are no cause for distress. In pragmatic theory and inquiry, we must accept that the best we can do is good enough, because we only have a certain (albeit large) set of tools and conceptualizations available to us.
A unique synthesis, this endeavor into pragmatic epistemology will be of interest to scholars and students of philosophy and cognitive science.
Epistemic logic is the branch of philosophical thought that seeks to formalize the discourse about knowledge. Its object is to articulate and clarify the general principles of reasoning about claims to and attributions of knowledge. This comprehensive survey of the topic offers the first systematic account of the subject as it has developed in the journal literature over recent decades.
Rescher gives an overview of the discipline by setting out the general principles for reasoning about such matters as propositional knowledge and interrogative knowledge. Aimed at graduate students and specialists, Epistemic Logic elucidates both Rescher's pragmatic view of knowledge and the field in general.
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.
G.W. Leibniz’s Monadology, one of the most important pieces of the Leibniz corpus, is at once one of the great classics of modern philosophy and one of its most puzzling productions. Because the essay is written in so condensed and compact a fashion, for almost three centuries it has baffled and beguiled those who read it for the first time.
Nicholas Rescher accompanies the text of the Monadology section-by-section with relevant excerpts from some of Leibniz’s widely scattered discussions of the matters at issue. The result serves a dual purpose of providing a commentary of the <I>Monadology</I> by Leibniz himself, while at the same time supplying an exposition of his philosophy using the Monadology as an outline.
The book contains all of the materials that even the most careful study of this could text could require: a detailed overview of the philosophical background of the work and of its bibliographic ramifications; a presentation of the original French text together with a new, closely faithful English translation; a selection of other relevant Leibniz texts; and a detailed commentary. Rescher also provides a survey of Leibniz’s use of analogies and three separate indices of key terms and expressions, Leibniz’s French terminology, and citations.
Rescher’s edition of the Monadology presents Leibniz’s ideas faithfully, accurately, and accessibly, making it especially valuable to scholars and students alike.
Historically, there has been great deliberation about the limits of human knowledge. Isaac Newton, recognizing his own shortcomings, once described himself as “a boy standing on the seashore . . . whilst the great ocean of truth lay all underscored before me.”
In Ignorance, Nicholas Rescher presents a broad-ranging study that examines the manifestations, consequences, and occasional benefits of ignorance in areas of philosophy, scientific endeavor, and ordinary life. Citing philosophers, theologians, and scientists from Socrates to Steven Hawking, Rescher seeks to uncover the factors that hinder our cognition.
Rescher categorizes ignorance as ontologically grounded (rooted in acts of nature-erasure, chaos, and chance-that prevent fact determination), or epistemically grounded (the inadequacy of our information-securing resources). He then defines the basis of ignorance: inaccessible data; statistical fogs; secreted information; past data that have left no trace; future discoveries; future contingencies; vagrant predicates; and superior intelligences. Such impediments set limits to inquiry and mean that while we can always extend our existing knowledge-variability here is infinite-there are things that we will never know.
Cognitive finitude also hinders our ability to assimilate more than a certain number of facts. We may acquire additional information, but lack the facility to interpret it. More information does not always increase knowledge; it may point us further down the path toward an erroneous conclusion. In light of these deficiencies, Rescher looks to the role of computers in solving problems and expanding our knowledge base, but finds limits to their reasoning capacity.
As Rescher's comprehensive study concludes, ignorance itself is a fertile topic for knowledge, and recognizing the boundaries of our comprehension is where wisdom begins.
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.
Gottfried Wilhelm Leibniz (1646-1716) possessed one of history's great minds. The German philosopher, mathematician, and logician invented (independently of Sir Isaac Newton) calculus. His metaphysics bequeathed a set of problems and approaches that drove the course of Western philosophy, from Kant's eighteenth century until the present day.
For over fifty years, the study of Leibniz has been a consistent passion for distinguished philosopher Nicholas Rescher. On Leibniz offers eleven of his essays, written with signature clarity, exploring the aspects of Leibniz's work and life that still resonate in the discipline of philosophy.
Rescher's essays are snapshots of Leibniz, lucidly drawn case studies that explain the fundamentals of his ontology: the theory of possible worlds, the world's contingency, space-time frameworks, and intermonadic relationships.
Several illuminating pieces reveal Leibniz as a substantial contributor to theories of knowledge. Discussions of his epistemology and methodology, its relationship to John Maynard Keynes and Talmudic scholarship, broaden the traditional view of Leibniz as a uniquely metaphysical thinker.
Rescher also explores, in four absorbing biographical essays, Leibniz's scholarly development and professional career in historical context. As a "philosopher courtier" to the Hanoverian court, Leibniz was associated with the leading intellectuals and politicians of his era, including Spinoza, Huygens, Newton, Queen Sophie Charlotte, and Czar Peter the Great.
A concluding essay holds up Leibniz's mode of philosophy as a role model for today's scholars. Rescher argues that many current problems can be effectively addressed with principles of process philosophy along lines inspired by Leibniz's monadology. On Leibniz is essential reading for students of Leibniz and Rescher alike.
Process Philosophy surveys the basic issues and controversies surrounding the philosophical approach known as “process philosophy.” Process philosophy views temporality, activity, and change as the cardinal factors for our understanding of the real—process has priority over product, both ontologically and epistemically. Rescher examines the movement’s historical origins, reflecting a major line of thought in the work of such philosophers as Heracleitus, Leibniz, Bergson, Peirce, William James, and especially A. N. Whitehead.
An examination of philosophical realism from the standpoint of pragmatic epistemology, this book addresses the core idea of Rescher's work in epistemology: that functional and pragmatic concerns exert a controlling influence on the conduct of rational inquiry and on the ways in which we can and should regard its products.
Pragmatism is widely regarded as a philosophical approach that stands at odds with realism, but Rescher takes a very different approach. He views pragmatism as a realistic position that can be developed from a pragmatic point of view, and utilizes a number of case studies to augment his position. Throughout, he shows how the pragmatic and purposive setting of our putative knowledge of the real world proves to be crucial for the constituting and also for the constitution of our knowledge.
The disagreement of philosophers is notorious. In this book, Rescher develops a theory that accounts for this conflict and shows how the basis for philosophical disagreement roots in divergent 'cognitive values'-values regarding matters such as importance, centrality, and priority. In light of this analysis, Rescher maintains that, despite this inevitable discord, a skeptical or indifferentist reaction to traditional philosophy is not warranted, seeing that genuine value-conflicts are at issue. He argues that philosophy is an important and worthwhile enterprise, notwithstanding its inability to achieve rationally constrained consensus on the issues. Given the nature of the enterprise, consensus is not a realistic goal, and failure to achieve it is not a defect. Accordingly, Rescher argues against the revisionist views proposed by Richard Rorty and Robert Nozick. His discussions are devoted to providing a clear view of why philosophical problems arise and how philosophers address them.
