Philosophers of science often make reference — whether tacitly or explicitly — to the notion of a scientific community. Sometimes, such references are useful to make our object of analysis tractable in the philosophy of science. For others, tracking or understanding particular features of the development of science proves to be tied to notions of a scientific community either as a target of theoretical or social intervention. We argue that the structure of contemporary scientific research poses two unappreciated, or at (...) least underappreciated, challenges to this concept of the “scientific community” in the philosophy of science. In particular, we will present two case studies from robotics research, broadly construed, which show that (1) the boundedness of the scientific community is threatened when private citizens can develop scientific and technological advances at minimal expense (democratization), and (2) the discreteness of scientific research programs is threatened by the complexly interrelated environment of contemporary scientific work (interconnectivity). Taken together, the extent of democratization and interconnectivity present a significant challenge for any practically oriented philosophy of science, one which we hope will be taken on directly by philosophers in the future.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Intuitionists and classical logicians use in common a large number of the logical axioms, even though they supposedly mean different things by the logical connectives and quantifiers — conquans for short. But Wittgenstein says The meaning of a word is its use in the language. We prove that in a definite sense the intuitionistic axioms do indeed characterize the logical conquans, both for the intuitionist and the classical logician.

In fragment B 18 (DK) Xenophanes asserts that ‘Not from the outset did the gods reveal all things to mortals’ but that ‘in time, as they seek, men discover better.’ The remark has been understood in different ways but is usually read as a rejection of the view of the gods as the givers of all good things and an expression of faith in the capacity of human beings to make progress through their own efforts. I argue that the ‘hymn (...) to progress’ reading of B 18 is unjustified by any other aspect of Xenophanes’ thought and at odds with his generally dour view of the intelligence and character of his fellow citizens. A detailed analysis of the fragment supports the view that Xenophanes is here rejecting belief in divine revelation through natural signs and affirming the value of historiê or inquiry in the form of travel and direct observation.

This article explores Presocratic epistemology, arguing that divine revelation is replaced as a warrant for knowledge with naturalistic accounts of how and what we humans can know; thus replacing earlier Greek pessimism about knowledge with a more optimistic outlook that allows for human discovery of the truth. A review of the relevant fragments and testimonia shows that Xenophanes, Alcmaeon, Heraclitus, and Parmenides—even Pythagoras and Empedocles—all moved some distance away from the older “god-oriented” view of knowledge toward a more secular and (...) optimistic outlook. But to get some sense of the dynamics at work in this transition this article begins, as virtually every account of early Greek thought must begin, with Homer and Hesiod. (shrink)

Myles Burnyeat maintains that Aristotelian epistêmê, in so far as it deals with explanations, is properly identified as understanding rather than as knowledge. Although Burnyeat is right in thinking that the cognitive achievement Aristotle typically has in mind is not justified true belief, Aristotelian epistêmê cannot be equated with understanding. On some occasions in Aristotle's writings (e.g. Apo 71a4), the term designates a particular science such as mathematics; on others (e.g. Apo 72b18-20), it designates the grasp of a first principle; (...) on others (e.g. Apo 94a20) it is a systematic grasp of fact and explanation that is properly termed understanding; and on still others (e.g. N. Ethics 1147a22) it is that combination of factual knowledge and competency in demonstration that qualifies as expertise or disciplinary mastery. (shrink)

Fragment B 1 of Parmenides describes a youth’s journey to the house of a goddess who enlightens him as to the nature of all things. The task of translating Parmenides’ Greek text is beset with many difficulties, most notably the phrase kata pant’ atê at B 1.3. There, the neuter accusative plural panta (‘all things’) combines with the feminine nominative singular atê (‘heaven sent blindness’) to render translation impossible. Some have proposed emending the text to read astê (‘down to all (...) cities’), understood in connection with the pathway of divine inspiration. Others reject the emendation in so far as the youth is said at B 1.27 to travel ‘far from the beaten path of men.’ I argue in defense of the reading kata pant’ a<s>tê in so far as references to pathways of inspiration and poetic journeys to the cities of men occur frequently in the poetry of Parmenides’ era.

Is there a place in scientific inquiry for guessing? Jonathan Cohen has recently argued that resorting to guesswork entails a loss of objectivity and regard for evidence which are essential to proper scientific investigation. I assess the merits of Cohen’s view first by taking as a test case Aristotle’s positive view of the role of guesswork (anchinoia) and conjecture (eustochia) in the search for the connections essential to the construction of scientific demonstrations. I then argue contra Cohen that one can (...) usefully employ guesswork while also employing reason; that it is possible to guess either intelligently or mindlessly; and consequently, that the use of guesswork need not represent a diminution in respect for the objectivity essential to scientific investigation. Although I would not claim that guesswork has a role to play in all scientific inquiry, there appear to be some datable instances of the useful and respectable scientific guess. (shrink)

In Posterior Analytics II 19 Aristotle likens the way in which sense perception gives rise to knowledge of the universal to the way in which one soldier’s ceasing his flight from the enemy leads other soldiers to do the same ‘heôs epi archên êlthen.’ Although the remark seems intended to characterize knowledge as the end result of an accumulative process, the concluding reference to ‘a starting point’ or archê has no clear meaning. I argue that the phrase can be plausibly (...) understood in light of Aristotle’s explanation of how a single calm thought can spread calm to other thoughts (Problems 917a29-33) and a single cloud can serve as a starting point (archê) for a revival of stormy weather (Problems 941a9-13). In addition, Aristotle elsewhere (e.g. Generation of Animals 788a13-16) speaks of the archê as the person or thing which initiates a process. Thus, when one soldier’s stopping causes another soldier to stop, this process can continue ‘until they come to the one who initiated the process.’ . (shrink)

In contrast to certain recent work, which supposes that the fetial priests were always responsible for the swearing of the oaths made upon the striking of a treaty and that the rituals they performed went unchanged for centuries, this paper argues that the treaty-making rituals of the Romans changed and developed, and that the ritual which the fetial priests performed may not have been devised until as late as the third century BC.
