Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

In a recent editorial, Raymond Spier expresses skepticism over claims that climate change is driven by human actions and that humanity should act to avoid climate change. This paper responds to this skepticism as part of a broader review of the science and ethics of climate change. While much remains uncertain about the climate, research indicates that observed temperature increases are human-driven. Although opinions vary regarding what should be done, prominent arguments against action are based on dubious factual and ethical (...) positions. Thus, the skepticisms in the recent editorial are unwarranted. This does not diminish the general merits of skeptical intellectual inquiry. (shrink)
Nobilitas is a study of the history of aristocratic philosophy from ancient Greece to the early twentieth century that aims at providing an alternative to the liberal democratic norms, which are propagated today as the only viable socio-political system for the world community. Jacob reveals that, contrary to popular belief, the social and cultural development of European civilization has, for twenty-five centuries, been based not on democratic or communist notions but, rather on aristocratic and nationalist notions. Beginning with the (...) political philosophies of Plato and Aristotle, and continuing through Renaissance and Baroque aristocratic philosophers, the German Idealists, and English and Italian nationalists, the study ends with the transformation of aristocratic philosophy in nineteenth century Germany into racist elitism. As such, the study includes a survey of the philosophical bases of racism and anti-Semitism. These topics have been systematically excluded from academic and political debate since the end of the last Great War. This study is a pioneering work in understanding and changing political ideologies. (shrink)
According to an influential view, one function of mirror neurons (MNs), first discovered in the brain of monkeys, is to underlie third-person mindreading. This view relies on two assumptions: the activity of MNs in an observer’s brain matches (simulates or resonates with) that of MNs in an agent’s brain and this resonance process retrodictively generates a representation of the agent’s intention from a perception of her movement. In this paper, I criticize both assumptions and I argue instead that the activity (...) of MNs in an observer’s brain is enhanced by a prior representation of the agent’s intention and that their task is to predictively compute the best motor command suitable to satisfy the agent’s intention.

Alva Noë’s version of the enactive conception in _Action in Perception_ is an important contribution to the study of visual perception. First, I argue, however, that it is unclear (at best) whether, as the enactivists claim, work on change blindness supports the denial of the existence of detailed visual representations. Second, I elaborate on what Noë calls the ‘puzzle of perceptual presence’. Thirdly, I question the enactivist account of perceptual constancy. Finally, I draw attention to the tensions between enactivism and (...) two trends in cognitive neuroscience: the two-visual systems model of human vision and the theory of internal forward models of action.

The tuning-fork model of human social cognition, based on the discovery of mirror neurons (MNs) in the ventral premotor cortex of monkeys, involves the four following assumptions: (1) mirroring processes are processes of resonance or simulation. (2) They can be motor or non-motor. (3) Processes of motor mirroring (or action-mirroring), exemplified by the activity of MNs, constitute instances of third-person mindreading, whereby an observer represents the agent's intention. (4) Non-motor mirroring processes enable humans to represent others' emotions. After questioning all (...) four assumptions, I point out that MNs in an observer's brain could not synchronically resonate with MNs in an agent's brain unless they discharged in a single brain in two distinct tasks at different times. Finally, I sketch a conceptualist alternative to the resonance model according to which a brain mechanism active in both the execution and the perception of e.g., the act of grasping is the neural basis of the concept of e.g., grasping.

We use psychological concepts (e.g., intention and desire) when we ascribe psychological states to others for purposes of describing, explaining, and predicting their actions. Does the evidence reported by Knobe show, as he thinks, that moral evaluation shapes our mastery of psychological concepts? We argue that the evidence so far shows instead that moral evaluation shapes the way we report, not the way we think about, others' psychological states.
I examine and discuss Jaegwon Kim's arguments against non-reductive physicalism in his book, Mind in a Physical World. I first examine the supervenience argument and then the multiple realization argument. Finally, I raise some questions about Kim's overall attitude towards mental realism, i.e., realism about mental properties.
Intentionality is the power of minds to be about, to represent, or to stand for, things, properties and states of affairs. The puzzles of intentionality lie at the interface between the philosophy of mind and the philosophy of language. The word itself, which is of medieval Scholastic origin, was rehabilitated by the philosopher Franz Brentano towards the end of the nineteenth century. ‘Intentionality’ is a philosopher's word. It derives from the Latin word intentio, which in turn derives from the verb (...) intendere, which means being directed towards some goal or thing. The entry falls into eleven sections. (shrink)
There are presently three broad approaches the project of naturalizing intentionality: a purely informational approach (Dretske and Fodor), a purely teleological approach (Millikan and Papineau), and a mixed informationally-based teleological approach (Dretske again). I will argue that the last teleosemantic theory offers the most promising approach. I also think, however, that the most explicit version of a pure teleosemantic theory of content, namely Millikan’s admirable theory, faces a pair of objections. My goal in this paper is to spell out Millikan’s (...) pure teleosemantic theory; then to present two objections; and finally to ask the question whether a teleosemantic framework can be saved from the objections.

Externalism is the view that the contents of many of a personâs propositional attitudes and perhaps sensory experiences are extrinsic properties of the personâs brain: they involve relations between the personâs brain and properties instantiated in his or her present or past environment. Privileged self-knowledge is the view that every human being is able to know directly or non-inferentially, in a way unavailable to anybody else, what he or she thinks or experiences. Now, if what I think (or experience) is (...) not in my brain, then it seems indeed as if I cannot have any privileged authoritative first-personal access to the content of what I think. Hence, externalism seems inconsistent with privileged self-knowledge. The purpose of this paper is to provide a road towards a conciliation between self-knowledge and externalism. (shrink)
As more and more historians acknowledge the central signifcance of science and technology with that of modern society, the need for a good, general history of the achievements of the Scientific Revolution has grown. Scientific Culture and The Making of the Industrial West seeks to explain this historical process by looking at how and why scientific knowledge became such an integral part of the culture of Europe in the seventeenth and eighteenth centuries, and how this in turn lead to the (...) Industrial Revolution. This comparative study not only looks at England, and its success, but follows through with the history of France, the Netherlands, and Germany. (shrink)
First, I argue that the narrow content of a thought cannot be identical with the linguistic meaning of the sentence used to express it. Secondly, I argue that the distinction between narrow content and linguistic meaning is not fatal to content-dualism. Thirdly I argue for the view that the proposition contributed by the clause prefixed by "that" is an interpretation of the believer's thought. Finally, I use this insight to provide an individualist account of Burge's thought-experiments such that recognition that (...) the truth-conditions of belief-ascriptions include aspects of the believer's environment does not entail that those environmental aspects are thereby parts of the contents of the person's thoughts.

I examine the question: How does visual perception give rise to visual knowledge of the world. Then, I give my reasons for why I think not all seeing is visual perception. Much seeing consists in the visual guidance of object-directed actions.
The behavior of Lyapunov exponents λ and dynamical entropies h, whose positivity characterizes chaotic motion, under Lorentz and Rindler transformations is studied. Under Lorentz transformations, λ and h are changed, but their positivity is preserved for chaotic systems. Under Rindler transformations, λ and h are changed in such a way..
I try to reconcile Dretske's representational theory of conscious mental states with Rosenthal's higher-order thought theory of conscious mental states by arguing that Rosenthal's HOT can make room for the notion of a state of consciousness whereby an invidual may be conscious of an object or property without thereby being conscious of being in such a state.
Jerry Fodor argued for an account of belief attribution very close to the theory of direct reference. I argue that his account conflicts with constraints on psychological explanation which he ought to accept.
The new prominence given to science for economic growth and industry comes with an increased policy focus on the promotion of commodification and commercialization of academic science. This paper posits that this increased interest in commodification is a new steering mechanism for governing science. This is achieved by first outlining what is meant by the commodification of scientific knowledge through reviewing a selection of literatures on the concept of commodification. The paper concludes with a discussion of how commodification functions as (...) a means for governing science. (shrink)
