There is a limited understanding amongst scientists, students and the public about realizing trust in scientific findings. This should be a paramount objective, or is it only about career ambition? What is the role of the individual? Scientists and the public need to know more about the link between the philosophy of science and the science research methods. There is a limited understanding of why accuracy is important and that it is not the same as precision. Also, there is (...) often the need to measure an approximation of a real system and the classic case is reductionism in biology versus whole organism biology. The author brings these topics together in terms of trusting in science. (shrink)

Therapists and their patients must deal with the negative sequelae of short term mating strategies. Implications for therapy of Gangestad & Simpson's strategic pluralism theory are compared with those of Buss's sexual strategies theory and Eagly's social role theory. Naive theories held by therapists and patients, as well as prevailing societal views, are posited as influential in determining the course and outcome of therapy.

Scientific realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it. In his book, Stathis Psillos gives us a detailed and comprehensive study which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and to modern sceptical empiricism. _Scientific Realism_ (...) explains that the history of science does not undermine the arguments for scientific realism, but instead makes it reasonable to accept scientific realism as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

The ambition of “scientific creationism” is to prove that science actually confirms religion. This is especially true in the case of Muslim creationism, which adopts a reasoning of a syllogistic type: divine revelation is truth; good science confirms truth; divine revelation is henceforth scientifically proven. Harun Yahya is a prominent Muslim “creationist” whose website hosts many texts and documentary films, among which “Evidence of the true faith in historical sources”. This is a small audiovisual production which, starting (...) from some archeological files, seeks to demonstrate that Qur’an truth precedes science but is equally proven by it. In this paper, we examine the organization of the scientific and religious argumentative repertoires and, in particular, what in each of them is taken as evidence and gets access to an authoritative status. It leads us to show how much this type of Muslim creationism constitutes a kind of scientism. (shrink)

Conference paper presented at the 10th International Congress of Logic, Methodology, and Philosophy of Science, Florence, Italy (19-25 August 1995). Extrapolation here refers to the act of inferring more widely from a limited range of known facts. This notion of extrapolation, especially when applied to past events, has recently been used to formulate a pragmatic definition of truth. This paper shows that this definition has serious problems. The pragmatic definition of truth has been formulated in discussions on internal (...) realism. In this paper, the basic internal realist starting point, as expounded in the works of H. Putnam and N. Jardine, will be taken to be the claim that the distinction between judgements that are true from judgements that are false is explainable from within our judgement-forming faculty — no recourse to the external world is necessary. The paper first shows how the pragmatic definition of truth involves a counterfactual statement. It then describes how the counterfactual definition is apparently justified by an inductive argument. In the final step, this justification is shown to be unsuccessful. (shrink)

The paper explores Hegel's theory of language, from the Subjective Spirit book of his Encyclopedia. Hegel distinguishes between linguistic signs, as arbitrary signifiers and words, which occur when the signs are filled with thought or meaning. Words have greater objectivity than signs. The words of the positive, empirical sciences are taken up into Hegelian Science (system), affording it greater objectivity, which it, reciprocally re-confers on its linguistic contents.

The idea of replication is based on the premise that there are permanent laws to be replicated and verified, and the scientific method is adequate for doing so. Scientific truth, however, is not absolute but relative to time and context, and the method used. Time and context are inextricably interwoven, in that time creates different contexts and contexts (e.g., Christmas Day vs. New Year’s Day) create different experiences of time, rendering psychological phenomena inherently variable. This means that (...) internal and external conditions fluctuate and are different in a replication study vs. the original. Thus, a replication experiment is just another empirical investigation that has no special status in the establishment of scientific truth. It is not the final arbiter of whether or not something exists. In their pursuit of homogeneous external conditions, replications have ignored the homogeneity of internal conditions. There is not a single replication reported in the literature that would have shown participants’ feelings and thoughts—both conscious and nonconscious—to be identical to those of the original participants. Experimental instructions can create varying ratios of conscious over nonconscious processing from one study to another. Ironically, every replication is a failure at the fundamentals of human psychology. While patterns can be discovered, they are not permanent or unchangeable laws of human behavior to be proven by the pinpoint statistical verification through replication. As scientific knowledge in physics is temporary and incomplete, should it be any surprise that science can only provide “temporary winners” for psychological knowledge of human behavior? (shrink)

Presenting portraits of many central figures in modern physics, including Stephen Hawking and Leonard Susskind, this critique of modern theoretical physics provides the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy.

While we typically think of culture as defined by geography or ethnicity (e.g., American culture, Mayan culture), the term also applies to the practices and expectations of smaller groups of people. Though embedded in the larger culture surrounding them, such subcultures have their own sets of rules like those that scientists do. Philosophy of science has as its main object of studio the scientific activity. A way in which we have tried to explain these scientific practices is from (...) the actual ontological commitments that scientists do through their scientific theories. Certainly, we know scientific theories through some specific scientific language, which is, in its turn, a subset of the natural language developed by a particular culture. This study is conducted to explore and evaluate some of the most important epistemological consequences of these ontological commitments, specially the so-called ‘truth-commitment’ and its relation with a linguistic-cultural framework. There is an interesting debate between advocates and opponents of scientific realistic view of the natural world. Some lines of scientific realism argumentation assure that: (i) Mature scientific theories are approximately true. (ii) There are entities and organisms in the world that correspond with the ontology presupposed by the best scientific theories within a specific domain of scientific research and (iii) The new acceptable scientific theories should explain why past theories were successful predecessors (Colyvan 2008, Cocchiarella 2007 & Laudan 1981). Contrary, anti- realist positions ensure against the realist’s true - claim that is a semantic commitment - that the purpose of scientific theories to found the truth it is simple an unattainable goal, especially if the kind of truth they are looking for is a corresponding relation between scientific theories and the ontology of the world. Anti-realist positions held that this relation could be circular and unknowable. I do believe that there is a deep confusion between the way in which we accede to the knowledge of the constitutive structures, entities and organisms of the world (which is an epistemological matter) and the way these structures, entities and organisms are (which is an ontological matter). It seems that there is a bridge between the epistemological and ontological aspect in need for conceptual clarification. I do propose that the type of link between the two extremes have to be linguistic in nature. (shrink)

We investigate whether there can be scientific truth if this truth depends ’inter alia’ on a true causal principle and if the principle strictly implies ’nature’s God’ ’qua’ a ’first cause’. If there is this ’cause’, then how does one know whether it or a natural cause was the cause of a phenomenon? Responses to this question involve examining critiques of the causal principle by Hume and Kant as well as by distinguishing logical from physical possibilities.

Scientific research aims to use reliable methods to produce generalizable new knowledge in order to understand the human condition and maximize human potential. The sanctity accorded to scientific research has been violated by numerous instances of research fraud, as well as deceptive and conflicted research that have seriously harmed people, subverted the evidence-base, wasted valuable resources, and undermined public trust. This deception by individuals has been fostered by the unrealistic expectations of society; facilitated by the complicity of institutions (...) and organisations; and sanctioned by the inaction of supposed gate-keepers. Re-defining misconduct as occurring on a continuum from irresponsible to fraudulent is the first step in confronting this inconvenient truth. Implementing and evaluating multiple strategies targeting systems and individuals that promote the responsible conduct of research, rather than merely exposing serious instances of misconduct by individuals, is urgently required to restore faith in the aspirations, integrity, and results of scientific research.

. In this essay I point toward the difficulties inherent in ontological objectivity and seek to restore our truth claims to validity through a relational ontology and the dynamic of coimplication in signals and noise. Theological examination of art and science points toward similarities between art, religion, and science. All three have often focused upon a “metaphysics of presence,” the desire for absolute presence of the object . If we accept a relational ontology, however, we must accept that the (...) revelation of presence is always simultaneously a concealment. This helps explain technoscientific achievement without recourse to a philosophically flawed objectivity. Twentieth‐century information theory shows the impossibility of a “pure signal.” By accepting that signal and noise are permanently interconnected, we begin to see how noise makes signal possible and even how noise becomes signal . Information theory thus underscores important similarities and leads toward new approaches in aesthetics, Christian theology, and scientific research. By comparing art, religion, and science, I argue that rejecting a metaphysics of presence without rejecting presence itself allows human beings to know the world. Although religion, science, and art often seek the absolute presence of their objects, they function better without. (shrink)

According to scientific realists, the predictive success of mature theories provides a strong epistemic basis for thinking that such theories are approximately true. However, we know that many theories once regarded as well-confirmed and predictively successful were eventually replaced with successor theories, and some claim this undermines the epistemic confidence we should have in the approximate truth of current science. Selective scientific realists in turn argue that if one can show that the predictive success of some rejected (...) theory T is a function of theoretical claims consistent with current science, then T’s failure doesn’t undermine the claim that current successful theories are approximately true. As such, Selective Scientific Realism (SSR) can be tested through historical examples. Showing that the predictive success of a failed theory is the result of theoretical features later rejected provides a counterexample to SSR. Conversely, SSR is supported if its explanation of the predictive success of failed theories--namely, that the factors which lead to predictive success in the failed theory survive in the successor theory--is able to handle a wide array of historical cases.

As the world watched the Fukushima reactors spew incalculable quantities of radionuclides into the sea and air and wondered what effect this would have on our health and that of generations to come, the warnings of Dr. Alice Stewart about low-dose radiation risk assumed a terrible timeliness. As industry, governments, and the media attempted to quiet the alarms, assuring us that radioactive releases will dilute and disperse and become too miniscule to matter, the reassurances of Sir Richard Doll, foremost among (...) Stewart's detractors, also became relevant. It is clear, as proponents and opponents of nuclear energy thrash it out, that there is not much more scientific consensus about the hazards of low-dose radiation .. (shrink)

In this book Jeremy Dunning-Davies deals with the influence that "conventional wisdom" has on science, scientific research and development. He sets out to explode' the mythical conception that all scientific topics are open for free discussion and argues that no-one can openly raise questions about relativity, dispute the 'Big Bang' theory, or the existence of black holes, which all seem to be accepted facts of science rather than science fiction. In today's modern climate with "Britain's radioactive refuse heap (...) already big enough to fill the Royal Albert Hall" (Edmund Conway, Economics Editor The Daily Telegraph 28.11.06), it is alarming that there are potential advances in hadronic mechanics which could conceivably pave the way for new clean energies and even a safe in-house method for the disposal of nuclear waste, that have not even been considered by the present establishment. These examples are from the field of physics but there can be little doubt that outside factors have affected the progress of most, if not all, branches of science for many years. Factors other than purely scientific ones still appear to be exerting tremendous influences on progress in a wide variety of fields. Is it too idealistic or nai;ve, to expect that science should remain pure and stay unaffected by such factors? Dr Dunning-Davies presents a beautifully written argument that if science is to progress, and be of any real use, these external factors must be held at bay. (shrink)

ABSTRACTThis discussion note aims to contribute to the ongoing debate over the nature of scientific progress. I argue against the semantic view of scientific progress, according to which scientific progress consists in approximation to truth or increasing verisimilitude. If the semantic view of scientific progress were correct, then scientists would make scientific progress simply by arbitrarily adding true disjuncts to their hypotheses or theories. Given that it is not the case that scientists could make (...) scientific progress simply by arbitrarily adding true disjuncts to their hypotheses or theories, it follows that the semantic view of scientific progress is incorrect.

What is the relation between coherence and truth? This paper rejects numerous answers to this question, including the following: truth is coherence; coherence is irrelevant to truth; coherence always leads to truth; coherence leads to probability, which leads to truth. I will argue that coherence of the right kind leads to at least approximate truth. The right kind is explanatory coherence, where explanation consists in describing mechanisms. We can judge that a scientific theory (...) is progressively approximating the truth if it is increasing its explanatory coherence in two key respects: broadening by explaining more phenomena and deepening by investigating layers of mechanisms. I sketch an explanation of why deepening is a good epistemic strategy and discuss the prospect of deepening knowledge in the social sciences and everyday life. (shrink)

It is often claimed—especially by scientific realists—that science provides understanding of the world only if its theories are (at least approximately) true descriptions of reality, in its observable as well as unobservable aspects. This paper critically examines this ‘realist thesis’ concerning understanding. A crucial problem for the realist thesis is that (as study of the history and practice of science reveals) understanding is frequently obtained via theories and models that appear to be highly unrealistic or even completely fictional. So (...) we face the dilemma of either giving up the realist thesis that understanding requires truth, or allowing for the possibility that in many if not all practical cases we do not have scientific understanding. I will argue that the first horn is preferable: the link between understanding and truth can be severed. This becomes a live option if we abandon the traditional view that scientific understanding is a special type of knowledge. While this view implies that understanding must be factive, I avoid this implication by identifying understanding with a skill rather than with knowledge. I will develop the idea that understanding phenomena consists in the ability to use a theory to generate predictions of the target system’s behavior. This implies that the crucial condition for understanding is not truth but intelligibility of the theory, where intelligibility is defined as the value that scientists attribute to the theoretical virtues that facilitate the construction of models of the phenomena. I will show, first, that my account accords with the way practicing scientists conceive of understanding, and second, that it allows for the use of idealized or fictional models and theories in achieving understanding.

A rationalist and realist model of scientific revolutions will be constructed by reference to two categories of criteria of theory-evaluation, denominated indicators of truth and of beauty. Whereas indicators of truth are formulateda priori and thus unite science in the pursuit of verisimilitude, aesthetic criteria are inductive constructs which lag behind the progression of theories in truthlikeness. Revolutions occur when the evaluative divergence between the two categories of criteria proves too wide to be recomposed or overlooked. This (...) model of revolutions depends upon a substantial new treatment of aesthetic criteria in science with which much of the paper will therefore be occupied. (shrink)

The paper seeks to answer two new questions about truth and scientific change: What lessons does the phenomenon of scientific change teach us about the nature of truth? What light do recent developments in the theory of truth, incorporating these lessons, throw on problems arising from the prevalence of scientific change, specifically, the problem of pessimistic meta-induction?

Scientific realism is a thesis about the success of science. Most traditionally: science has been so successful at prediction and guiding action because its best theories are true (or approximately true or increasing in their degree of truth). If science is in the business of doing its best to generate true theories, then we should turn to those theories for explanatory knowledge, predictions, and guidance of our actions and decisions. Views that are popular in contemporary philosophy of science (...) about scientific modeling and the centrality of idealization create several challenges for this traditional form of scientific realism. Yet the basic idea behind scientific realism that science has been and will continue to be epistemically successful is deeply appealing. This chapter explores the challenges posed by idealization and scientific modeling to motivate a scientific realism fully divorced from the idea that science is in the business of generating true theories. On the resulting view, the objects of scientific knowledge are causal patterns, so this knowledge only ever provides partial, simplified accounts of a complex reality. This variety of selective realism better accommodates the nature of our present-day scientific successes and offers an interpretation of scientific progress that resists the antirealist’s pessimism.

This paper describes a theory of accuracy or approximate truth and applies it to problems in the realist interpretation of scientific theories. It argues not only that realism requires approximate truth, but that an adequate theory of approximation also presupposes some elements of a realist interpretation of theories. The paper distinguishes approximate truth from vagueness, probability and verisimilitude, and applies it to problems of confirmation and deduction from inaccurate premises. Basic results are cited, but details appear (...) elsewhere. Objections are surveyed, including arguments by Miller, Laymon, and Laudan. Comparison is made with Niiniluoto's theory of verisimilitude, and the utility of his theory for realism assessed. (shrink)

I argue that one good reason for Scientific Realists to be interested in correspondence theories is the hope they offer us of being able to state and defend realistic theses in the face of well-known difficulties about modern physics: such theses as, that our theories are approximately true, or that they will tend to approach the truth. I go on to claim that this hope is unlikely to be fulfilled. I suggest that Realism can still survive in the (...) face of these difficulties, as a claim about the kind of theories we want to aim for. I relate this conception of Realism to various contemporary discussions, both by realists and antirealists. (shrink)

Ian Hacking defines a “style of scientific thinking” loosely as a “way to find things out about the world” characterised by five hallmark features of a number of scientific template styles. Most prominently, these are autonomy and “self-authentication”: a scientific style of thinking, according to Hacking, is not good because it helps us find out the truth in some domain, it itself defines the criteria for truth-telling in its domain. I argue that Renaissance medicine, Mediaeval (...) “demonology”, and magical thinking pass muster as scientific according to Hacking's criteria. However, application of these thought styles to the entities they introduce generates statements that logically imply a set of “ordinary” statements—or what Bernard Williams calls “plain truths”—which, contra the claims of autonomy and self-authentication, allows styles to be assessed from a style- independent perspective. Using Williams’ notion of plain truth, I show that Renaissance medicine, demonology, and magical thinking, in reality issue in many plain falsehoods. This confronts us with what I call Hacking's dilemma: either define stricter necessary conditions on being a style of scientific thinking, or concede that some styles albeit scientific are not as good at finding things out about the world as others. I make three suggestions to deal with the dilemma. (shrink)

In this paper I examine various ways in whichphilosophers have made connections between truth andnatural selection. I introduce several versions ofthe view that mechanisms of true belief generationarise as a result of natural selection and argue thatthey fail to establish a connection between truth andnatural selection. I then turn to scientific truthsand argue that evolutionary accounts of the origin ofscientific truth generation mechanisms also fail. Iintroduce David Hull's selectionist model ofscientific development and argue that his account (...) ofscientific success does not rely on connecting truthand natural selection. I argue that Hull's model,which severs the connection between truth andselection, can account for some aspects of scientificchange, but it still leaves us plenty of questionsabout what aspects of our individual cognitive make-upcontribute to scientific change and how they do so. I introduce an evolutionary approach to scientificcognition that shows how some of these questions canbe answered without making an explanatory appeal toselection for true belief generating mechanisms.
