Nicholas Rescher

SOME TWENTY YEARS AGO I wrote a small book entitled Conceptual Idealism, which ultimately saw the light of print in 1973. In the wake of its appearance, a considerable number of reviews were published in the philosophical literature, and their perusal, as well as discussions with various colleagues, brought home to me how easy it is to misunderstand and misconstrue a position which, to its exponent, seems quite clear and straightforward. In due course, I have come to think it useful to exploit the benefit of distant hindsight to try to restate the position more clearly and to try to safeguard it against various misunderstandings that have come to view. The present essay is the result of this endeavor.

I propose to formulate and expound a version of idealism. The position at issue does not maintain the causal thesis that matter is somehow the product of mind. Nor, a fortiori, is it spiritualism—the theory that only minds exist and that all else is the product of their functioning. Rather, this doctrine, which I shall call conceptual idealism, holds not merely the trivial thesis that mind is at work in our conceiving of reality, but the more significant and daring doctrine that mind underlies the conception of reality. Beginning with the traditional rationalist thesis that the mind makes a substantive and constitutive contribution to the shaping of our conception of reality, conceptual idealism goes beyond this to hold that the mind makes this formative contribution in terms that to some extent involve a reference to itself: that key elements in our picture of natural reality are painted with mentalistic coloration.

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.

How is one properly to allocate credit for making a discovery in science or elsewhere where the conjoint effort of several individuals is involved? When a group of investigators cooperates in making a discovery, how should the credit for this achievement be apportioned among them to assure that everyone receives their proper share?The problem being considered here is not that of assessing importance—of determining how much credit there is to go around. That is something else again. The present problem, rather, is that of how that credit, be it great or small, should be allocated to the parties responsible for the discovery at issue? It is, accordingly, not the amount of credit but its distribution that is at issue

Cost, expected benefits, and risks are paramount in grant agencies' decisions to fund scientific research. In _Cognitive Economy,_ Nicholas Rescher outlines a general theory for the cost-effective use of intellectual resources, amplifying the theories of Charles Sanders Pierce, who stressed an “economy of research.” Rescher discusses the requirements of cooperation, communication, cognitive importance, cognitive economy, as well as the economic factors bearing on induction and simplicity. He then applies his model to several case studies and to clarifying the limits imposed on science by economic considerations.

Our world is enormously sophisticated and nature's complexity is literally inexhaustible. As a result, projects to describe and explain natural science can never be completed. This volume explores the nature of complexity and considers its bearing on our world and how we manage our affairs within it.Rescher's overall lesson is that the management of our affairs within a socially, technologically, and cognitively complex environment is plagued with vast management problems and risks of mishap. In primitive societies, failure to understand how things work can endanger a family or, at worst, a clan or tribe. In the modern world, man-made catastrophes on the model of Chernobyl can endanger millions, possibly even risking the totality of human life on our planet. Rescher explains "technological escalation" as a sort of arms race against nature in which scientific progress requires more powerful technology for observation and experimentation, and, conversely, scientific progress requires the continual enhancement of technology. The increasing complexity of science and technology (and, in consequence, of social systems) along with problems growing faster than solutions confront us with major management and decision problems.This study is the first of its kind. There have been many specialized studies of complexity in physics and computation theory, but no overall analysis of the phenomenon. Although Rescher offers a sobering outlook, he also believes that complexity entails mixed blessings: our imperfect knowledge provides a rationale for putting forth our best efforts. Rescher urges us to gear the conduct of life's practical affairs to the demands of a complex world. This highly readable and accessible volume will be of interest to those interested in philosophy, the philosophy of science, science policy studies, and future studies.

This book by distinguished philosopher Nicholas Rescher seeks to clarify the idea of what a conditional says by elucidating the information that is normally transmitted by its utterance. The result is a unified treatment of conditionals based on epistemological principles rather than the semantical principles in vogue over recent decades. This approach, argues Rescher, makes it easier to understand how conditionals actually function in our thought and discourse. In its concern with what language theorists call pragmatics--the study of the norms and principles governing our use of language in conveying information--Conditionals steps beyond the limits of logic as traditionally understood and moves into the realm claimed by theorists of artificial intelligence as they try to simulate our actual information-processing practices.The book's treatment of counterfactuals essentially revives an epistemological approach proposed by F. P. Ramsey in the 1920s and developed by Rescher himself in the 1960s but since overshadowed by the now-dominant possible-worlds approach. Rescher argues that the increasingly evident liabilities of the possible-worlds strategy make a reappraisal of the older style of analysis both timely and desirable. As the book makes clear, an epistemological approach demonstrates that counterfactual reasoning, unlike inductive inference, is not a matter of abstract reasoning alone but one of good judgment and common sense
