The presence of vegetation on railway tracks threatens track safety and longevity. However, vegetation inspections in Sweden are currently being carried out manually. Manually inspecting vegetation is very slow and time consuming. Maintaining an even quality standard is also very difficult. A machine vision-based approach is therefore proposed to emulate the visual abilities of the human inspector. Work aimed at detecting vegetation on railway tracks has been split into two main phases. The first phase is aimed at detecting vegetation on (...) the tracks using appropriate image analysis techniques. The second phase is aimed at detecting the rails in the image to determine the cover of vegetation that is present between the rails as opposed to vegetation present outside the rails. Results achieved in the current work indicate that the machine vision approach has performed reasonably well in detecting the presence/absence of vegetation on railway tracks when compared with a human operator.

It is widely believed that a person's traits can function as reasons for loving her. Notable contemporary work in the philosophy of love has taken the rejection of this premise as its point of departure. As far as I can tell, none of that work has engaged with a careful philosophical exposition of the view under discussion. In the following pages, I will defend the idea of trait-based love against three of its critics and one of its advocates. I will (...) discuss work on this topic by Harry Frankfurt, Niko Kolodny and David Velleman, arguing that their criticisms fail and that the alternatives they offer to trait-based love create more difficulties than they solve. What these authors have in common is a deflationary approach to love that reduces it to a beneficent disposition, a valuing relationship and a visceral form of moral regard, respectively. I will compare these to the multiplex, nuanced depiction of trait-based love in Plato's Symposium. While it is plausible that love can motivate a beneficent disposition, develop in relationships and entails moral regard, I will argue that the attempt to reduce it to any of the foregoing fails. Frankfurt, Kolodny and Velleman reject trait-based love in part because they think it would differ in unacceptable ways from the love most of us practice. Plato advocates the cultivation of a love that in some respects resembles the picture of trait-based love the contemporary authors balk at. However, unlike those critics, he appreciates that trait-based love need not resemble the ideal he proposes. His richer view of love accounts for elements such as need and feeling that the contemporary thinkers are driven to implausibly bracket as distractions. As I will try to show, the most compelling criticisms of Platonic love do not tell against its responsiveness to the loved one's traits. I will argue that trait-based love is consistent with an intuitive picture of love and that this commonsense approach is more defensible than competing views in these texts. These authors' disagreements about what can count as reasons for love are bound up with the differences in what each takes love to be. Thus, in the course of arguing for trait-based love, I will critically assess their various proposals as to the nature of love. (shrink)

Locke was born in Wrington, Somerset, on 29 August 1632. After the Civil War he was sent to Westminster School, and in 1652 to Christ Church, Oxford. A feature of the university in Locke's early years was growing interest in the natural sciences, fostered by, amongst others, Robert Boyle, John Wilkins, and Robert Hooke. After graduating, Locke was much attracted to the work of these men, and soon he was engaged in medical research with Robert Boyle. He remained in Oxford (...) until 1667, when a chance meeting with Anthony Ashley Cooper, later Lord Shaftesbury, led to his joining Shaftesbury's London household, which from then on became Locke's usual residence, and where he acted as Shaftesbury's personal physician, conducted research with Thomas Sydenham. and became a Fellow of the Royal Society.

This book recalls, for nonscientific readers, the history of quantum mechanics, the main points of its interpretation, and Einstein's objections to it, together with the responses engendered by his arguments. We point out that most popular discussions on the strange aspects of quantum mechanics ignore the fundamental fact that Einstein was correct in his insistence that the theory does not directly describe reality. While that fact does not remove these counterintuitive features, it casts them in a different light."--page vi.

Each title in the "Key Issues" series aims to set the work in its historical context. In this collection of contemporary responses to "Leviathan", attention is focused on its critics who attacked Hobbes's moral, political and religious ideas in a series of pamphlets and short books.

Seventeenth-century philosophy scholars come together in this volume to address the Insiders--Descartes, Spinoza, Leibniz, Locke, and Hobbes--and Outsiders--Pierre Gassendi, Kenelm Digby, Theophilus Gale, Ralph Cudworth and Nicholas Malebranche--of the philosocial canon, and the ways in which reputations are created and confirmed. In their own day, these ten figures were all considered to be thinkers of substantial repute, and it took some time for the Insiders to come to be regarded as major and original philosophers. Today these Insiders all feature in (...) the syllabi of most history of philosophy courses taught in western universities, and the papers in this collection, contrasting the stories of their receptions with those of the Outsiders, give an insight into the history of philosophy which is generally overlooked.

Forensic science error rates are needlessly high. Applying the perspective of veritistic social epistemology to forensic science could produce new institutional designs that would lower forensic error rates. We make such an application through experiments in the laboratory with human subjects. Redundancy is the key to error prevention, discovery, and elimination. In the “monopoly epistemics” characterizing forensics today, one privileged actor is asked to identify the truth. In “democratic epistemics,” several independent parties are asked. In an experiment contrasting them, democratic (...) epistemics reduced the rate at which biased observers obscured the truth by two-thirds. These results highlight, first, the potential of “epistemic systems design,” which employs the techniques of economic systems design to address issues of veracity rather than efficiency, and second, the value of “experimental epistemology,” which employs experimental techniques in the study of science.

It is common to assume that if Locke is to be regarded as a consistent epistemologist he must be read as holding that either ideas are the objects of perception or that (physical) objects are. He must either be a direct realist or a representationalist. But perhaps, paradoxical as it at first sounds, there is no reason to suppose that he could not hold both to be true. We see physical objects and when we do so we have ideas. We (...) see or hear birds and bells but we also have visual and auditory ideas of birds and bells. This suggestion is explored through examination of what Locke says about perception in his Elements of Natural Philosophy and the accounts offered both by Locke in the Essay Concerning Human Understanding and by some of Locke's successors.

My theme in this essay is the relation of misfortune – and other occasions for regret – to the affirmation of life. R. Jay Wallace believes there is an antagonistic relation that produces a schism between our affirmative attitudes and our reasons and considered judgments. On his view, our attachments to the persons and projects that give meaning to our lives lead us to affirm states of affairs it would be more appropriate to regret. I argue that the attitude of (...) affirmation can acknowledge and do justice to reasons for regret. Wallace fails to appreciate the implications of the Nietzschean positions he cites as precedents; he assumes the past has a meaning that is fixed and insulated from the future. Drawing on Nietzsche, I argue that the affirmation of life is a coherent project of bestowing meaning on a historical sequence going forward into the future. (shrink)

John Rogers explores the concepts of recognition, command and authority and tests their validity in several cases presented by Hobbes, ranging from parental authority to the omnipotence of God. The general thesis he defends is that, for Hobbes, autonomy always goes hand in hand with the possession of power. Even for the individuals in a civil society, there is no autonomy but in a condition of empowerment. But, at the same time, the strength of the laws of nature rests in (...) their rationality, and there can be no doubt that their compelling force comes from their being rational. The comparison with mathematical theorems furnishes an important element of understanding, since the laws of nature are conclusions concerning that which conduces to the conservation of oneself. Although there is an empirical element in the deduction of those practical theorems, this is no objection to the analogy being drawn, since this empirical element belongs to the learning process and not to the rationality of the law itself. In the light of this conception of natural law, Hobbes thus appears as a rationalist in morals and politics. (shrink)

The present essay looks to add to the body of literature that seeks to clarify the nature of vengeance and evaluate it morally. However, unlike previous philosophical investigations of vengeance, my essay examines it not from the standpoint of impersonal justice but from the perspective of the one who seeks it, to determine whether it is good for the would-be avenger. The values I measure it by are fulfillment and self-knowledge. The paper has two major parts. In the first, I (...) argue that vengefulness is motivated by two ends: allaying a sense of vulnerability and preserving a positive self-conception. The emotional benefits of a vengeful disposition, I claim, come at the expense of self-knowledge. They are therefore unstable and prone to give way when vengefulness is translated into action. In the second part, I try to substantiate this claim by examining two criticisms of vengeance: that its pursuit can diminish the avenger by consuming him and that it is self-defeating. Framing vengefulness within broader psychoanalytic accounts of the repetition compulsion and projection, I endorse versions of both criticisms that tie vengeance’s failure to provide fulfillment to some of the ways in which it occludes self-knowledge.

The scholarly attention lavished on William James’ case study in the “Sick Soul” lecture in The Varieties of Religious Experience of a man disturbed by the vision of an epileptic patient has generally not approached this case as a religious experience. To deepen our understanding of religious experience, I show that this case study can be understood as religious using elements of the theory of religion expounded throughout James’ text. I argue that it can be understood as a stage in (...) the process of conversion James lays out. The omission of a subsequent stage highlights James’ reasons for rejecting healthy-mindedness as a philosophically adequate perspective and illustrates his claim that the strivings of the conscious mind can stunt the conversion process. Drawing on other philosophical, psychological, and literary texts, I argue that the content of the vision James describes points to solitude as a source of religious disquiet. (shrink)

Philosophers and natural scientists have often drawn a distinction between two kinds of properties that physical objects may have. It is particularly associated with atomistic accounts of matter, and is as old as the ancient Greek theories of Democritus and Epicurus. According to the atomists, matter consists of tiny particles ‐ atoms ‐ having no other properties than those such as shape, weight, solidity, and size. Other putative properties ‐ for example, those of color, taste, and smell ‐ were regarded (...) as the names of experiences caused by the impact of particles on an observer, and had no independent existence as qualities in the object. Since the seventeenth century it has been normal to characterize the division between these two supposedly different kinds of properties as the primary‐secondary quality distinction. (shrink)
