  • Theory of Change and Organizational Development Strategy INTRODUCTION Dear Reader
    Theory of Change and Organizational Development Strategy INTRODUCTION Dear Reader: The Fetzer Institute was founded in 1986 by John E. Fetzer with a vision of a transformed world, powered by love, in which all people can flourish. Our current mission, adopted in 2016, is to help build the spiritual foundation for a loving world. Over the past several years, we have been identifying and exploring new ways to make our vision of a loving world a reality. One aspect of this work has been the development of a new conceptual frame resulting in a comprehensive Theory of Change. This document aspires to ground our work for the next 25 years. Further, this in-depth articulation of our vision allows us to invite thought leaders across disciplines to help sharpen our thinking. This document represents a moment when many strands of work and planning by the Institute board and staff came together in a very powerful way that enabled us to articulate our Theory of Change. However, this is a dynamic, living document, and we encourage you to read it as such. For example, we are actively developing detailed goals and action plans, and we continue to examine our conceptual frame, even as we make common cause with all who are working toward a shared and transformative sacred story for humanity in the 21st century. We continue to use our Theory of Change to focus our work, inspire and grow our partnerships, and identify the most pressing needs in our world. I look forward to your feedback and invite you to learn about how our work is coming alive in the world through our program strategies, initiatives, and stories at Fetzer.org.

I show that this view—if taken literally—leads to absurdities. In particular, this view equates theories that are distinct, and it distinguishes theories that are equivalent. Furthermore, the semantic view lacks the resources to explicate interesting theoretical relations, such as embeddability of one theory into another.

  • Introduction to Philosophy of Science
    INTRODUCTION TO PHILOSOPHY OF SCIENCE The aim of philosophy of science is to understand what scientists did and how they did it, where history of science shows that they performed basic research very well. Therefore to achieve this aim, philosophers look back to the great achievements in the evolution of modern science that started with the Copernicus with greater emphasis given to more recent accomplishments. The earliest philosophy of science in the last two hundred years is Romanticism, which started as a humanities discipline and was later adapted to science as a humanities specialty. The Romantics view the aim of science as interpretative understanding, which is a mentalistic ontology acquired by introspection. They call language containing this ontology “theory”. The most successful science sharing in the humanities aim is economics, but since the development of econometrics that enables forecasting and policy, the humanities aim is mixed with the natural science aim of prediction and control. Often, however, econometricians have found that successful forecasting by econometric models must be purchased at the price of rejecting equation specifications based on the interpretative understanding supplied by neoclassical macroeconomic and microeconomic theory. In this context the term “economic theory” means precisely such neoclassical equation specifications. Aside from economics Romanticism has little relevance to the great accomplishments in the history of science, because its concept of the aim of science has severed it from the benefits of the examination of the history of science. The Romantic philosophy of social science is still resolutely practiced in immature sciences such as sociology, where mentalistic description prevails, where quantification and prediction are seldom attempted, and where implementation in social policy is seldom effective and often counterproductive.

But that conclusion can be justified only if attempts to reconcile the two theories end in failure.

    Passmore, J. (1967). Logical Positivism. In P. Edwards (Ed.). The Encyclopedia of Philosophy (Vol. 5, 52- 57). New York: Macmillan. LOGICAL POSITIVISM is the name given in 1931 by A. E. Blumberg and Herbert Feigl to a set of philosophical ideas put forward by the Vienna circle. Synonymous expressions include "consistent empiricism," "logical empiricism," "scientific empiricism," and "logical neo-positivism." The name logical positivism is often, but misleadingly, used more broadly to include the "analytical" or "ordinary language philosophies developed at Cambridge and Oxford. HISTORICAL BACKGROUND The logical positivists thought of themselves as continuing a nineteenth-century Viennese empirical tradition, closely linked with British empiricism and culminating in the antimetaphysical, scientifically oriented teaching of Ernst Mach. In 1907 the mathematician Hans Hahn, the economist Otto Neurath, and the physicist Philipp Frank, all of whom were later to be prominent members of the Vienna circle, came together as an informal group to discuss the philosophy of science. They hoped to give an account of science which would do justice -as, they thought, Mach did not- to the central importance of mathematics, logic, and theoretical physics, without abandoning Mach's general doctrine that science is, fundamentally, the description of experience. As a solution to their problems, they looked to the "new positivism" of Poincare; in attempting to reconcile Mach and Poincare; they anticipated the main themes of logical positivism. In 1922, at the instigation of members of the "Vienna group," Moritz Schlick was invited to Vienna as professor, like Mach before him (1895-1901), in the philosophy of the inductive sciences. Schlick had been trained as a scientist under Max Planck and had won a name for himself as an interpreter of Einstein's theory of relativity.
