Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

_'Never before has there been so many and such dreadful weapons in so many irresponsible hands.'__ - Karl Popper, from the Preface_ _All Life is Problem Solving_ is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life. This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War (...) and after the collapse of communism.

'I want to begin by declaring that I regard scientific knowledge as the most important kind of knowledge we have', writes Sir Karl Popper in the opening essay of this book, which collects his meditations on the real improvements science has wrought in society, in politics and in the arts in the course of the twentieth century. His subjects range from the beginnings of scientific speculation in classical Greece to the destructive effects of twentieth century totalitarianism, from major figures (...) of the Enlightenment such as Kant and Voltaire to the role of science and self-criticism in the arts. The essays offer striking new insights into the mind of one of the greatest twentieth century philosophers. (shrink)

This article argues the following points. The Hobbesian hypothesis, which we define as the claim that all people are better off under state authority than they would be outside of it, is an empirical claim about all stateless societies. It is an essential premise in most contractarian justifications of government sovereignty. Many small-scale societies are stateless. Anthropological evidence from them provides sufficient reason to doubt the truth of the hypothesis, if not to reject it entirely. Therefore, contractarian theory has not (...) done what it claims to do: it has not justified state sovereignty to each person subject to it by demonstrating that they benefit from that authority. To be justified in contractarian terms, states have to do something to improve the living standards of disadvantaged people under their rule. (shrink)

Much contemporary ontological inquiry takes place within the so-called ‘Quinean tradition’ but, given that some aspects of Quine’s project have been widely abandoned even by those who consider themselves Quineans, it is unclear what this amounts to. Fortunately recent work in metaontology has produced two relevant results here: a clearer characterisation of the metaontology uniting the aforementioned Quineans, most notably undertaken by Peter van Inwagen, and a raft of criticisms of that metaontology. In this paper I critique van Inwagen’s Quinean (...) metaontology, finding that certain challenges, supplemented by pressure to reflect more closely Quine’s work, should drive Quineans to adopt a stronger metaontology incorporating more of Quine’s radical views. I conclude that while van Inwagen’s Quineanism is problematic there are prospects for a viable, more wholeheartedly Quinean, metaontology. (shrink)

Recently, much discussion of Hegel has focused on the nature of his idealism, and especially on its relation to Kant’s transcendental idealism—a doctrine whose meaning is itself still much in dispute. It is clear enough that Hegel calls himself an “absolute idealist,” and that he is a major figure in the “German idealist” tradition, but the precise meaning and value of falling under the idealist label is not so clear. Moreover, some recent interpretations have suggested ways in which Hegel can (...) be termed a realist, and for all interpreters it is conceded that there is a peculiarly “objective” nature to Hegel’s idealism that serves to set it apart from most other versions.

In these comments I briefly discuss three aspects of the empiricist account of the epistemic role of experience that Anil Gupta develops in his Empiricism and Experience. First, I discuss the motivations Gupta offers for the claim that the given in experience should be regarded as reliable. Second, I discuss two different ways of conceiving of the epistemic significance of the phenomenology of experience. And third, I discuss whether Gupta's account is able to deliver the anti-skeptical results he intends it (...) to. I close by suggesting that, once fully fleshed out, Gupta's account is best understood in terms of the fusion of certain core ideas within both the empiricist and the rationalist traditions.

BackgroundSuicide research aims to contribute to a better understanding of suicidal behaviour and its prevention. However, there are many ethical challenges in this research field, for example, regarding consent and potential risks to participants. While studies to-date have focused on the perspective of the researchers, this study aimed to investigate the views and experiences of members of Human Research Ethics Committees (HRECs) in dealing with suicide-related study applications.MethodsThis qualitative study entailed a thematic analysis using an inductive approach. We conducted semi-structured (...) interviews with a purposive sample (N = 15) of HREC Chairs or their delegates from Australian research-intensive universities. The interview guide included questions regarding the ethical concerns and challenges in suicide-related research raised by HREC members, how they dealt with those challenges and what advice they could give to researchers.ResultsThe analysis identified four main themes: (1) HREC members’ experiences of reviewing suicide-related study applications, (2) HREC members’ perceptions of suicide, suicide research, and study participants, (3) Complexity in HREC members’ decision-making processes, and (4) HREC members’ relationships with researchers.ConclusionsReliance on ethical guidelines and dialogue with researchers are crucial in the assessment of suicide-related study applications. Both researchers and HREC members may benefit from guidance and resources on how to conduct ethically sound suicide-related studies. Developing working relationships will be likely to help HRECs to facilitate high quality, ethical suicide-related research and researchers to conduct such research. (shrink)

This paper sets Kant in the broader context of modern philosophy as a whole by suggesting that Kant not be understood primarily as attempting to i) defeat skepticism, ii) promote “scientism”, or iii) develop a radically new ontology. It suggests that Kant’s philosophy aims to take the claims of common sense at face value and then attempts to mediate between such claims and the apparently conflicting claims of science. Accordingly, philosophy is a systematic articulation of the sphere of conceptual frameworks (...) that mediate between the extremely informal and the highly formal levels of judgment within our complex objective picture of the world. Thus, for Kant, philosophy lies in between common sense and science by attempting to mediate between them. (shrink)

Problems from Kant is distinctive in the way that it combines the crisp and often extremely critical style of argumentation found in Jonathan Bennett’s work with a very helpful grasp of the much more metaphysical character of the leading trends in current systematic philosophy. Although the book defends a phenomenalist reading of Kant's transcendental idealism that is not far from Bennett's empiricist interpretation, it also stresses many points that derive mostly from a philosophical and interpretative sympathy for the rationalist tradition (...) and a revival of modal considerations in the spirit of David Lewis and Alvin Plantinga. Since there is not enough room here to go into the many points on which I very much agree with the rationalist side of Van Cleve’s reading, I will take this occasion to play the role of critic and concentrate on one of the few areas in which it appears we have some serious disagreements. These disagreements are worthy of special attention because they arise in the chapter that overlaps the least with Van Cleve’s earlier publications, and they concern a topic that all would agree is at the very center of the Critique, namely Kant’s Transcendental Deduction of the categories.

The beginning of a universal culture of rationality in Judaism did not begin in the so called »Medieval Jewish philosophy« but had its precedents in the Biblical Wisdom Literature and in Rabbinic legal rationality. The Medieval Jewish authors, therefore, did not regard the medieval Philosophy propounded by Jewish authors as »Jewish philosophy« but as a participation of Jews in just another specific phase of universal rationalism. The reason why Jewish authors in the 19th century nevertheless alleged that there existed a (...) specific »Jewish philosophy« at the side of a German, Christian or English philosophy had its reason in the exclusion of Jewish thought from the new leading science of interpretation of human existence in Europe, namely philosophy, by German intellectuals and universities. If we despite this want to retain the term of »Jewish philosophy« we should be aware that there cannot be an essential difference to general philosophy but merely a heuristic pragmatism. (shrink)

Recently the geometry of quantum states has been under considerable development. Every good geometry deserves, if possible, an accompanying trigonometry. I will here introduce such a trigonometry to accompany the geometry of quantum states.

The analogy between colonization and space exploration was by no means invented by H.G. Wells in his novel about the invasion of Mars, The War of the Worlds , or the science fiction in its wake. The analogy goes back to the age of the Copernican Revolution, which put the Earth on a par with other planets and thus suggested that those, too, could be inhabited by man-like creatures. Since then, popularizers of astrophysics have nurtured the notion that "we" or (...) "they" could fill the roles of colonizers and natives, though it remained a matter of debate who had to play which role. Among those given to such contemplation we find Bruno, Kepler, Wilkins, and Huygens, along with scientifically trained literati such as Francis Godwin, Fontenelle, Swift. Together, they constitute a noteworthy phenomenon of the early modern age of discovery and conquest. (shrink)
