A convenient and practical method is presented for the generation of unbiased random sequences. The method is based on combining discrete outputs and does not require either precisely specified and unbiased input or complex procedures and equipment.

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Review of N. Immler: Das Familiengedächtnis der Wittgensteins (2011).

Electronic mail and information exchange on the World Wide Web have in recent years developed into indispensible features of scholarly activity. The speed and convenience of computer-mediated communication across the planet are rapidly changing the established patterns of academic transactions. While thousands of philosophers have begun to take advantage of e-mail, web-servers or digital text repositories, systematic exploration of the newly available technology has been lagging behind. There is, it has to be admitted, a colourful offspring of postmodern writing celebrating (...) this alleged telematic revolution. I give just one example. (shrink)

In the period since the 2008 Wall Street crash, little consensus has emerged on its causes or actions to prevent a recurrence. Our capability for rational decision making was overwhelmed. Viewing the entire financial system as a huge, richly interconnected organization suggests that its structure and associated management practices are suited for a far simpler environment. An organization that is large relative to its environment and sufficiently complex to require the coordination of specialized expertise cannot function by enabling decision makers (...) to respond only to local demands. The resulting inability to recognize critical interdependencies and the nature of their risk makes periodic catastrophic failure likely. Specifically, compartmentalization of information, influence, and reward creates a myopic decision environment in which individual decision makers are unlikely to make effective or ethical decisions. Useful criteria for evaluating solutions can be suggested by considering the interaction of two factors: limited human information processing capability and the effect of motivation on information processing. Taken together, they suggest that human information processing is both limited and opportunistic. We cannot process all information available and the information selected for processing narrows to that needed to achieve salient rewards. Because of this, the organization's reward practices and their effect on motivation are a critical variable. Large financial rewards contingent upon short term, local, simplistic measures inevitably narrow the focus of decision maker's attention to a small part of the system. In contrast, dominant intrinsic motivation is rooted in awareness of, and responsibility for, broader outcomes. Each type of motivation differs in its requirements for sharing of information, influence, and reward. These, in turn, determine the adaptability of the organization to complexity and change. While this has significant ethical implications, its logic rests on the limitations of human information processing and motivation. Aligning human motivation and information flow to the demands of a complex, turbulent financial environment is the challenge we must meet to prevent further cataclysms. (shrink)

Inclusive fitness theory provides conditions for the evolutionary success of a gene. These conditions ensure that the gene is selfish in the sense of Dawkins (The selfish gene, Oxford University Press, Oxford, 1976): genes do not and cannot sacrifice their own fitness on behalf of the reproductive population. Therefore, while natural selection explains the appearance of design in the living world (Dawkins in The blind watchmaker: why the evidence of evolution reveals a universe without design, W. W. Norton, New York, (...) 1996), inclusive fitness theory does not explain how. Indeed, Hamilton’s rule is equally compatible with the evolutionary success of prosocial altruistic genes and antisocial predatory genes, whereas only the former, which account for the appearance of design, predominate in successful organisms. Inclusive fitness theory, however, permits a formulation of the central problem of sociobiology in a particularly poignant form: how do interactions among loci induce utterly selfish genes to collaborate, or to predispose their carriers to collaborate, in promoting the fitness of their carriers? Inclusive fitness theory, because it abstracts from synergistic interactions among loci, does not answer this question. Fitness-enhancing collaboration among loci in the genome of a reproductive population requires suppressing alleles that decrease, and promoting alleles that increase the fitness of its carriers. Suppression and promotion are effected by regulatory networks of genes, each of which is itself utterly selfish. This implies that genes, and a fortiori individuals in a social species, do not maximize inclusive fitness but rather interact strategically in complex ways. It is the task of sociobiology to model these complex interactions. (shrink)
