Euler ’s wave theory of light developed from a mere description of this notion based on an analogy between sound and light to a more and more mathematical elaboration on that notion. He was very successful in predicting the shape of achromatic lenses based on a new dispersion law that we now know is wrong. Most of his mathematical arguments were, however, guesswork without any solid physical reasoning. Guesswork is not always a bad thing in physics if it leads to (...) new experiments or makes the theory coherent with other theories. And Euler tried to find such experiments. He saw the construction of achromatic lenses, the explanation of colors of thin plates and of the opaque bodies as proof of his theory. When it came to the fundamental issues, the correctness of his dispersion law and the prediction of frequencies of light he was not at all successful. His wave theory degenerated, and it was not until Augustin Fresnel introduced transverse waves and an elaborate notion of interference that the wave theory again progressed. (shrink)

Historians of science have proposed many theories to explain why Copernicus rejected the Ptolemaic system and advanced his own heliocentric system. In support of his new cosmological system Copernicus always employed theoretical considerations and never the existence of discrepancies between the positions given in the Tables and those observed. It is shown that the general acceptance of the heliocentric system through the work of the astronomers resulted not so much from empirical considerations but rather from the fact that this system (...) was suited to a comprehensive, general dynamics.

The paper lists all the predictions and observations of eclipses of Jupiter's satellites 1668–1678 and compares them with modern computations of the these eclipses by J. H. Lieske. We discuss Roemer's method that led to his discovery of the retardment of light and finally we shall interpret Roemer's calculations.

This article investigates the hitherto under-examined relations between affirmative action, paternalism and respect. We provide three main arguments. First, we argue that affirmative action initiatives are typically paternalistic and thus disrespectful towards those intended beneficiaries who oppose the initiatives in question. Second, we argue that not introducing affirmative action can also be disrespectful towards these potential beneficiaries because such inaction involves a failure to adequately recognize their moral worth. Third, we argue that the paternalistic disrespect involved in affirmative action is (...) alleviated when the potential beneficiaries’ preferences against such initiatives are adaptive. We conclude that although there is a relevant sense in which paternalistic affirmative action is disrespectful, it may well be more disrespectful not to pursue such policies. (shrink)

In defense of nudging policies, proponents have pointed out that choice architecture is inevitable. However, critics have objected that shaping people’s choices in an intentional way is not inevitable and involves an objectionable substitution of judgment, with the choice architect imposing his will on others. Accordingly, the inevitability of choice architecture in general does not provide reason to accept intentional nudges. In contrast to this view, the paper argues that precisely because the choice architects will unavoidably contribute to people’s choices, (...) it is permissible for them to consider the content of the choices that their choice architecture promotes. Specifically, I argue that it is often within choice architects’, including states’, own legitimate sphere of control whether they want to contribute to other people’s behaviors through their organization of the choice architecture. It is argued that such intentional choice architecture does not involve objectionable substitution of judgment. (shrink)

A common objection to paternalism concerns its expressive content. Many reject paternalistic policies and actions on the ground that they arguably involve insulting expressions of disrespect toward those subjected to them. The paper challenges this view. It argues that refraining from acting paternalistically can be disrespectful. Specifically, the paper argues that there is a relevant way in which A disregards the moral worth of B if A stands idly by when B is about to act very imprudently. If true, treating (...) others with equal respect and concern, as relational egalitarians and others rightly ask us to do, will somewhat surprisingly sometimes involve treating them paternalistically.

Opponents of paternalism have sought to formulate non-paternalistic arguments for some seemingly reasonable but apparently paternalistic policies. This article addresses two such non-paternalistic arguments—the public charge argument and the psychic harm argument. The gist of both arguments is that a person’s imprudent or risky behavior often affects the interests of others adversely, and that this justifies restricting his or her behavior in various ways. The article shows that both arguments face important problems. It thus throws serious doubt on the prospect (...) of holding on to apparently sound and well-founded policies whilst at the same time avoiding paternalism. (shrink)

A classicist, philosopher, and poet, Poul Martin Møller was an important figure in the Danish Golden Age. The traumatic event of the death of his wife led him to think more profoundly about the question of the immortality of the soul. In 1837 he published his most important philosophical treatise, "Thoughts on the Possibility of Proofs of Human Immortality," presented here in English for the first time. It was read and commented upon by the leading figures of the Golden Age, (...) such as Søren Kierkegaard. It proved to be the last important work that Møller wrote before his death in March of 1838 at the age of 43. (shrink)

There exists a common view that for theories related by a ‘duality’, dual models typically may be taken ab initio to represent the same physical state of affairs, i.e. to correspond to the same possible world. We question this view, by drawing a parallel with the distinction between ‘interpretational’ and ‘motivational’ approaches to symmetries.

This article explores yet another paradox – aside from the privacy paradox – related to the datafication of media: citizens trust least the media they use most It investigates the role that daily life plays in shaping the trust that citizens place in datafied media. The study reveals five sets of heuristics guiding the trust assessments of citizens: characteristics of media organisations, old media standards, context of use and purpose, experiences of datafication and understandings of datafication. The article discusses the (...) use of these heuristics and the value that everyday life holds in assessing trust in datafied media. It concludes that, guided by a partial ‘structure of perception’ and enticed into trusting datafied media in the context of their daily lives, citizens may be highly concerned by the datafication of media but use them nevertheless.

The music ensemble has often been used as an analogy of organisation processes in general. Many versions of this analogy presuppose a specific organisation structure in the ensemble with clearly defined leader-follower relationships from which we can learn important points about successful leadership. This paper wishes to draw attention to the wide variety of organisation processes that may occur in a music ensemble, some of which are not dependent on leadership. Through the outlines of a logical analysis of a coordination (...) problem, it is argued that the music performance is in fact exemplary of a situation in which individual dedication to a goal promotes coordination in the entire group.

Kant's Critique of Pure Reason, his main work of theoretical philosophy, frequently uses metaphors from law. In this first book-length study in English of Kant's legal metaphors and their role in the first Critique, Sofie Møller shows that they are central to Kant's account of reason. Through an analysis of the legal metaphors in their entirety, she demonstrates that Kant conceives of reason as having a structure mirroring that of a legal system in a natural right framework. Her study shows (...) that Kant's aim is to make cognisers become similar to authorized judges within such a system, by proving the legitimacy of the laws and the conditions under which valid judgments can be pronounced. These elements consolidate her conclusion that reason's systematicity is legal systematicity. (shrink)

In this article I assess the Invariance Principle, which states that only quantities that are invariant under the symmetries of our theories are physically real. I argue, contrary to current orthodoxy, that the variance of a quantity under a theory’s symmetries is not a sufficient basis for interpreting that theory as being uncommitted to the reality of that quantity. Rather, I argue, the variance of a quantity under symmetries only ever serves as a motivation to refrain from any commitment to (...) the quantity in question. (shrink)
