In endeavoring to secure our knowledge against the skeptic's critique, we can acquire a great deal of useful insight into its nature. For it emerges that our knowledge of matters of objective fact is potentially defeasible and that what we claim as "our knowledge of the world" is and is bound to remain presumably incomplete, potentially incorrect, and possibly inconsistent as well. The explanation and analysis of these circumstances is the object of the present critique of skepticism. The book will accordingly endeavor to sift the wheat from the chaff in the skeptic's argument.

The prime and paramount factor that characterizes the Catholic philosopher is a respect for the Catholic philosophical tradition. To respect a person or a tradition is to see it as a bearer of value; respect does not automatically entail agreement. The Catholic philosophical tradition is not doctrinally unified, but is defined by a mutuality of involvement in a common project: that of developing a perspective that enables reason and religion to exist in a holistic unicity that fructifies each through its interaction with the other. Catholic philosophers should respect their intellectual tradition because it is an important part of acquiring their identity as thinkers and persons. Three useful approaches to appropriating and respecting a tradition are: (1) restoration and revival; (2) preservation of issues by re-opening and re-examining its questions; and (3) revivification of its spirit.

The project of inquiry into the nature's modus operandi faces extensive and deeprooted difficulties. In particular there are four major problems: (1) data undetermine theories, (2) theories undetermine facts, (3) reality transcendes the descriptive resources of language, and (4) reality transcendens the explanatory resources of language. The lesson of these delierations is not a sceptical despair but a healthy dose of cognitive humility. In pursuing the aims of science we can expect improvement but not completion: however deeply we push our inquiries into nature, we cannot get to the bottom of things.

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.
