Bilim felsefesinin en temel problemlerinden biri olan sınırlandırma problemi belirli bir ölçüt vasıtası ile bilimi, bilimsel olmayan ya da sahte/sözde bilim olan etkinliklerden ayırt edip edemeyeceğimizi konu edinmektedir. Literatüre baktığımızda felsefeciler –özellikle bilim felsefecileri– bilimin doğasını karakterize etme girişiminde bulunurken bilim dilinin mantıksal yapısına ya da bilimin tarihsel süreçlerine odaklanarak, bilimi bilimsel olmayan ya da sahte-bilim olan etkinliklerden ayırt etmişlerdir. Bu çalışma ise farklı bir yaklaşım benimseyerek sınırlandırma problemine, felsefecilerin değil, bilim insanlarının perspektifi ile bakmayı amaçlamaktadır. Bu sebeple alanında deneyimli (...) ve çeşitli bilim dallarında profesör olan otuz bilim insanı ile niteliksel araştırma yöntemlerinden biri olan yapılandırılmış görüşme tekniği uygulanmıştır. Bu görüşmeler aracılığıyla bilim insanlarının sınırlandırma problemi hususunda öne sürdükleri görüşler açığa çıkartılıp değerlendirilmiştir. Değerlendirme neticesinde üç temel bulguya ulaşılmıştır. İlki, sınırlandırma problemine ilişkin sorularımıza bilim insanları tarafından getirilen yanıtların birçoğu temel felsefi yaklaşımlarla uyuşmaktadır. Elde ettiğimiz verileri farklı temalar altında analiz ettiğimiz bu çalışmada, sınırlandırma problemine dair yaygın felsefi görüşlerin, bilim insanlarının görüşleri ile anlamlı benzerlikler taşıdığı kısımlar vurgulanmıştır. İkincisi, sınırlandırma problemi ve bu problemlerle ilişkili diğer meseleler üzerinde felsefi olarak sağlanamayan uzlaşma, bilim insanları arasında da mevcuttur. Ne var ki bu ihtilaf dengeli bir biçimdedir, öyle ki benzer yanıtlara sahip olan bilim insanları baskın bir grup sayısına ulaşmamıştır. Üçüncü ve son olarak, bilim insanlarının bilim felsefesinin temel problemlerine yüksek oranda yabancı olduğu görülmektedir. Bu bulgu, her ne kadar nicel olmayan bir yolla ölçülmüşse de verilerin dikkatli analizi durumun bu yönde olduğunu göstermektedir. Tüm bu temel bulgular ışığında, genel değerlendirmemiz, farklı türden yapılandırılmış görüşmelerin çok daha detaylı sonuçlar temin edebileceğidir. (shrink)

Homoeopathy is commonly recognised as pseudoscience. However, there is, to date, no systematic discussion that seeks to establish this view. In this paper, we try to fill this gap. We explain the nature of homoeopathy, discuss the notion of pseudoscience, and provide illustrative examples from the literature indicating why homoeopathy fits the bill. Our argument contains a conceptual and an empirical part. In the conceptual part, we introduce the premise that a doctrine qualifies as a pseudoscience if, firstly, its proponents (...) claim scientific standing for it and, secondly, if they produce bullshit to defend it, such that, unlike science, it cannot be viewed as the most reliable knowledge on its topic. In the empirical part, we provide evidence that homoeopathy fulfils both criteria. The first is quickly established since homoeopaths often explicitly claim scientificity. To establish the second, we dive into the pseudo-academic literature on homoeopathy to provide evidence of bullshit in the arguments of homoeopaths. Specifically, we show that they make bizarre ontological claims incompatible with natural science, illegitimately shift the burden of proof to sceptics, and mischaracterise, cherry-pick, and misreport the evidence. Furthermore, we demonstrate that they reject essential parts of established scientific methodology and use epistemically unfair strategies to immunise their doctrine against recalcitrant evidence.

While medicine is solidly grounded on scientific areas such as biology and chemistry, some argue that it is in its essence not a science at all. With medicine playing a substantial societal role, addressing questions about the scientific nature of medicine is of obvious urgency. This paper takes on such a task and starts by consulting the literature on the “demarcation” problem in the philosophy of science. Learning from failures of earlier approaches, it proposes that we adopt a Deflated Approach, (...) which acknowledges that “science” is a family resemblance concept that admits differences of degrees to nonscientific undertakings. Then, drawing on Paul Hoyningen-Huene’s ; account of systematicity and Alexander Bird’s analysis of examples from the history of medicine, the paper argues that medicine meets the requirement for systematicity on all dimensions and thereby qualifies as a science. The paper then considers and defuses two objections. First, it is shown that nonepistemic differences linked to the distinctive duality of medicine do not warrant thinking that medicine is not science. Second, against some recent criticism, the paper uses homeopathy as an example to show that systematicity can succeed as a demarcation criterion. (shrink)

Second, against some recent criticism (Oreskes in Synthese 196: 881–905, 2019), the paper uses homeopathy as an example to show that (synchronic and diachronic) systematicity can succeed as a demarcation criterion.

This paper argues for a novel account of deceitful scientific communication, as “wishful speaking”. This concept is of relevance both to philosophy of science and to discussions of the ethics of lying and misleading. Section 1 outlines a case-study of “ghost-managed” research. Section 2 introduces the concept of “wishful speaking” and shows how it relates to other forms of misleading communication. Sections 3–5 consider some complications raised by the example of pharmaceutical research; concerning the ethics of silence; how research strategies—as (...) well as the communication of results—may be misleading; and questions of multiple authorship. The conclusion suggests some more general conclusions. (shrink)

In this article, I reply to the preceding articles by Naomi Oreskes, Chrysostomos Mantzavinos, Brad Wray, Sarah Green, Alexander Bird, and Timothy Lyons. These articles contain a number of objections and suggestions concerning systematicity theory, as developed in my book ystematicity: The Nature of Science.
