This article aims to build a bridge between two areas of philosophical research: the structure of kinds and metaphysical modality. Our central thesis is that kinds typically involve super-explanatory properties, and that these properties are therefore metaphysically essential to natural kinds. Philosophers of science who work on kinds tend to emphasize their complexity, and are generally resistant to any suggestion that they have essences. The complexities are real enough, but they should not be allowed to obscure the way that kinds are typically unified by certain core properties. We show how this unifying role offers a natural account of why certain properties are metaphysically essential to kinds.
Joint action is agrowing field of research, spanning across the cognitive, behavioral, and brain sciences as well as receiving considerable attention amongst philosophers. Ia rgue that there has been asignificant oversight within this field concerning the possibility that many joint actions are driven, at least in part, by agents' social motivations rather than merely by their shared intentions. Social motivations are not directly related to the (joint) target goal of the action. Instead, when agents are mutually socially motivated in joint action this is because they find acting with others rewarding in its own right. Moreover the involvement of social motivation in joint action typically enables individuals to achieve the long-term benefits associated with being part of asocial bond. I argue that taking social motivations into account better prepares us for explaining a broader range of joint actions, including those that are of an antagonistic, competitive, or explorative character. Finally, Is how that recognizing the importance of social motivations entails that joint actions (in general) should be understood as having the two primary functions of (1) achieving the intended target outcome of an action, and (2) attaining the benefits related to being part of as ocial bond.
Attempts have been made to establish nanoethics as a new sub-discipline of applied ethics. The nature of this sub-discipline is discussed and some issues that should be subsumed under nanoethics are proposed. A distinction is made between those issue that may ensue once nanotechnology applications become available and procedural issues that should be integrated into the decision structure of the development. A second distinction relates to the central value of the ethical issue. The conditions for the ethical debate differ depending on whether the value(s) in question is internal to the technological development (i.e. health and safety) or external to it (i.e. privacy, equity etc).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
