Worlds of Truth: A Philosophy of Knowledge

Worlds of Truth: A Philosophy of Knowledge explicates and expands upon the formidable body of work by the author. Evincing a strong affinity for pragmatic philosophy as well as a dedication to analytical treatment of central problems, Israel Scheffler here provides an overview of his philosophy of knowledge, as developed in previous work and incorporating new views he has developed in recent thinking.

The inquiries here focus on truths: how truths are sought, what they express, and how they shape the worlds we inhabit. Consideration of these three topics highlights the interrelations of epistemology, symbolism, and metaphysics, all treated in a scientific spirit.

Scheffler s philosophy of knowledge incorporates several unfamiliar corollaries. Eschewing absolutism, the author nevertheless defends absolute truth; upholding systematic relativity, he also commends the ideal of objectivity; propounding his new doctrine of plurealism, he defends realism but rejects its usual concomitant monism, thus implying that we live not in one actual world but in many, all revealed by scientific investigation. Science itself, he holds, is not unitary in its motivation, but dual, spurred by two master impulses: the one to reduce, economize and systematize, the other to unsettle, explore and cultivate new areas for inquiry, an endless process belying the myth of a final theory of everything.

"The book will be of interest to philosophers working on pragmatism, pluralism, relativism, and justification". (International Studies In The Philosophy Of Science, 1 December 2010)

"This volume will be useful for specialists in pragmatism, but perhaps not sufficiently original for all collections." (CHOICE, October 2009)
