This paper argues that fitness is most usefully understood as those properties of organisms that are explanatory of survival in the broadest sense, not merely descriptive of reproductive success. Borrowing from Rosenberg and Bouchard , fitness in this sense is ecological in that it is defined by the interactions between organisms and environments. There are three sorts of ecological fitness: the well-documented ability to compete, the ability to cooperate , and a third sense of fitness that has received insufficient attention in evolutionary theory, the ability to construct. Following Lotka, it can be understood thermodynamically as the ability to maintain or enlarge the energy-circulating capacity of an ecosystem. An organism that does this could end with its gene frequency unchanged but its probability of survival enhanced since it would sustain or increase the total carrying capacity of its ecosystem. Photosynthesizers and other autotrophs are obvious candidates for organisms that are fit in the constructive sense, but any organisms, including heterotrophs, can exhibit constructive fitness if they have some mechanism for channeling external flows of free energy into their ecosystems. I will briefly examine the prospects for the human species in the light of these considerations

Sherlock Holmes is reputed to have once remarked impatiently to his earnest but plodding colleague Watson, “How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?” In Quantum Non-Locality and Relativity, Tim Maudlin offers us a thorough and provocative argument based on this methodological principle. Maudlin insists that all explanations of the mysterious non-local correlations of quantum mechanics must by now be rejected except one: distant events in quantum systems really are “causally implicated” in a way that directly challenges the theory of relativity. Physicists and philosophers of science have made virtually every conceivable move to avoid this unsettling conclusion, including tinkering with the basic formalism or interpretation of the theory, and Arthur Fine’s oddly postmodernist recommendation that we should abandon as outmoded “essentialism” all hope of explaining the correlations. However, the threat to relativity just won’t go away. Maudlin argues that we should have paid better attention in the first place to J. S. Bell, who “concluded that violations of [his] inequality demonstrate that the world is not locally causal.... Instead of trying to deny these non-local influences, we should begin to study the role such influences must play in generating the phenomena”.

The most pressing problems facing humanity today - over-population, energy shortages, climate change, soil erosion, species extinctions, the risk of epidemic disease, the threat of warfare that could destroy all the hard-won gains of civilization, and even the recent fibrillations of the stock market - are all ecological or have a large ecological component. in this volume philosophers turn their attention to understanding the science of ecology and its huge implications for the human project. To get the application of ecology to policy or other practical concerns right, humanity needs a clear and disinterested philosophical understanding of ecology which can help identify the practical lessons of science. Conversely, the urgent practical demands humanity faces today cannot help but direct scientific and philosophical investigation toward the basis of those ecological challenges that threaten human survival. This book will help to fuel the timely renaissance of interest in philosophy of ecology that is now occurring in the philosophical profession. Provides a bridge between philosophy and current scientific findings Covers theory and applications Encourages multi-disciplinary dialogue

Not too many metaphysicians in these hypercritical times would dream of offering a theory of everything, but Storrs McCall, who modestly compares his new book to The Origin of Species, claims that his theory may accomplish nothing less than to "illuminate, perhaps even resolve" problems such as "the direction and flow of time; what causation consists of; the nature of scientific laws; the interpretation of quantum mechanics; objective probability; counterfactuals and related conditionals; the identity of individuals across possible worlds; essential properties... practical reason and decision, and the problem of free will". His attempt is breathtaking in its thoroughness and ingenuity.
