Models and fictions in science

Non-actual model systems discussed in scientific theories are compared to fictions in literature. This comparison may help with the understanding of similarity relations between models and real-world target systems. The ontological problems surrounding fictions in science may be particularly difficult, however. A comparison is also made to ontological problems that arise in the philosophy of mathematics.

Perilous thoughts: comment on van Fraassen

Bas van Fraassen’s empiricist reading of Perrin’s achievement invites the question: whose doubts about atoms did Perrin put to rest? This comment recontextualizes the argument and applies the notion of empirical grounding to some contemporary work in behavioral biology.     

A selectionist explanation for the success and failures of science

I argue that van Fraassen’s selectionist explanation for the success of science is superior to the realists’ explanation. Whereas realists argue that our current theories are successful because they accurately reflect the structure of the world, the selectionist claims that our current theories are successful because unsuccessful theories have been eliminated. I argue that, unlike the explanation proposed by the realist, the selectionist explanation can also account for the failures of once successful theories and the fact that sometimes two competing theories are both equally successful.

Positive psychology at work: A conceptual review,state-of-practice assessment,and a look ahead

Positive psychological principles have become increasingly prevalent in the workplace in recent years. However, the field still lacks a comprehensive and practice-based overview of this important trend. The present article focuses on reviewing recent research in positive psychology as it relates to the workplace, including research regarding constructs such as resilience, appreciative inquiry, empowerment, gratitude, psychological capital, work engagement, supervisor and organizational support, positive teamwork and co-worker relations, and positive leadership. For each, we synthesize research examining the nature of the construct itself, its nomological network, individual- and organizational-level outcomes, and how organizations can enhance each within their employees for increased organizational success and enhanced employee experience. Finally, we discuss gaps in the relevant literature and make specific recommendations regarding how to ameliorate such oversights in order to enhance the rigor of positive workplace research as well as the frequency and efficacy of relevant organizational interventions.     

A proposed universal model of problem solving for design,science and cognate fields

A modestly generic, innovative, problem solving process with roots in the study of design and scientific research problem solving is presented and motivated. It is argued to be the shared core process of all problem solving. At its heart is a recognition of five foci or nodes of change vital to the process (changes in problem and solution formulation, method, constraints, and partial solution proposals) together with a bootstrap marked by the formation of higher order knowledge about problem solving in the domain in tandem with the solving of specific problems, the essential feature of all learned improvement. None of these elements is entirely original, but the way they are made explicit and developed (rather than folded into fewer, more abstract, boxes) is argued to provide fresh understanding of the organisation and power of the process to deal with complex practical problems.     

Giving Science a Bad Name: Politically and Commercially Motivated Fallacies in BSE Inquiry

It is a feature of scientific inquiry that it proceeds alongside a multitude of non-scientific interests. This statement is as true of the scientific inquiries of previous centuries, many of which brought scientists into conflict with institutionalised religious thinking, as it is true of the scientific inquiries of today, which are conducted increasingly within commercial and political contexts. However, while the fact of the coexistence of scientific and non-scientific interests has changed little over time, what has changed with time is the effect of this coexistence on scientific inquiry itself. While scientists may no longer construct their theories with various religious dictates in mind, growing commercial and political interests in science have served to distort the interpretation of science. Using the U.K.’s recent crisis with bovine spongiform encephalopathy (BSE) as my context, I examine two ways in which this distortion has occurred – the interpretation of the science of BSE by politicians and by commercial parties for the purposes of justifying policy decisions and informing the public of risk, respectively. Fallacious reasoning, I contend, is the manifestation of this distortion in these contexts. In demonstration of this claim, I examine how politicians and commercial parties alike have employed two fallacies in their assessments of the science of BSE. These fallacies extend in novel ways the set of so-called traditional informal fallacies. The interpretation of science, I conclude, is a rich context in which to conduct a study of fallacious reasoning; moreover, such a study can contribute in significant ways, I argue, to the public understanding of science.     

Reliabilism and the Abductive Defence of Scientific Realism

According to the “no-miracles argument” (NMA), truth is the best explanation of the predictive-instrumental success of scientific theories. A standard objection against NMA is that it is viciously circular. In Scientific Realism: How Science Tracks Truth Stathis Psillos has claimed that the circularity objection can be met when NMA is supplemented with a reliabilist approach to justification. I will try to show, however, that scientific realists cannot take much comfort from this policy: if reliabilism makes no qualifications about the domain where inference to the best explanation is reliable, scientific realists flagrantly beg the question. A qualified version of reliabilism, on the other side, does not entitle us to infer the realist conclusion. I conclude, then, that Psillos’s proposal does not make any significant progress for scientific realism.

A Pragmatic Case against Pragmatic Scientific Realism

Pragmatic Scientific Realism (PSR) urges us to take up the realist aim or the goal of truth although we have good reason to think that the goal can neither be attained nor approximated. While Newton-Smith thinks that pursuing what we know we cannot achieve is clearly irrational, Rescher disagrees and contends that pursuing an unreachable goal can be rational on pragmatic grounds—if in pursuing the unreachable goal one can get indirect benefits. I have blocked this attempt at providing a pragmatic justification for the realist aim of PSR on precisely the same pragmatic grounds—since there is a competing alternative to PSR, and the alternative can provide whatever indirect benefits PSR can offer while being less risky than it is, prudential reasoning favours the alternative to PSR. This undermines the pragmatic case for the realist aim of science since the instrumentalist alternative does not aim at the truth.     

Inquiry and Analysis: Dewey and Russell on Philosophy

In an environment characterized by the emergence of new and diverse (and often opposed) philosophical efforts, there is a need for a conception of philosophy that will promote the exchange and critical consideration of divergent insights. Depending upon the operative conception, philosophical efforts can be viewed as significant, insightful and instructive, or unimportant, misguided and not real philosophy. This paper develops John Dewey's conception of philosophy as a mode of inquiry in contrast with Bertrand Russell's conception of philosophy as a mode of analysis. I argue that while Russell's analytic conception of philosophy justifies the dismissal of non-analytic philosophies, Dewey's conception of philosophy provides a theoretical framework for the comparison, evaluation and interaction of alternatives.
