Descartes's works are often treated as a unified, unchanging whole. But in Descartes's Changing Mind, Peter Machamer and J. E. McGuire argue that the philosopher's views, particularly in natural philosophy, actually change radically between his early and later works--and that any interpretation of Descartes must take account of these changes. The first comprehensive study of the most significant of these shifts, this book also provides a new picture of the development of Cartesian science, epistemology, and metaphysics. No changes in Descartes's (...) thought are more significant than those that occur between the major works The World and Principles of Philosophy. Often seen as two versions of the same natural philosophy, these works are in fact profoundly different, containing distinct conceptions of causality and epistemology. Machamer and McGuire trace the implications of these changes and others that follow from them, including Descartes's rejection of the method of abstraction as a means of acquiring knowledge, his insistence on the infinitude of God's power, and his claim that human knowledge is limited to that which enables us to grasp the workings of the world and develop scientific theories.

L’on considère quelques raisons en faveur du pessimisme et de l’optimisme ; et l’on arrive à ce résultat, qu’elles restent sur un terrain subjectif, où une décision scientifique entre les diverses conceptions est impossible. Pour faire de la question du pessimisme et de l’optimisme une question scientifique, il faut prendre pour problème la possibilité et la validité de l’évaluation, dans toute son étendue. Pessimisme et optimisme se transforment alors en positions, opposées l’une à l’autre, de la philosophie des valeurs, le (...) pessimisme niant totalement la validité des jugements de valeur, que l’optimisme affirme.

An explanatory gap exists between physics and experience, raising the hard problem of consciousness: why are certain physical systems associated with an experience of an external world from an internal perspective? The living mirror theory holds that consciousness can be understood as arising from the computational interaction between a living system and its environment that is required for the organism's existence and survival. Maintaining a boundary that protects the system against destructive forces requires an interaction between the organism and its (...) outside world that can be cast in terms of Bayesian inference. The living mirror theory holds that this computational interaction results in statistical properties of the material world that are, in the absence of life, only implicit, becoming explicit in informational terms. This is held to give rise to the beliefs in qualities that constitute consciousness. Consciousness is therefore a necessary feature of all living systems as, in a world governed by the second law of thermodynamics, survival depends on the construction of beliefs regarding the potentially destructive forces in the outside world. From this perspective, consciousness is shown to be not a property of the brain in particular but instead to be a necessary feature of the life process itself. (shrink)

Few current problems have become so confused as that of Value. Its increasing importance in all departments of modern thought has made it the focal point of so many diverse aspects that the result seems a mass of formidable contradictions. But these can never be overcome by attempting to simplify the situation, which must on the contrary be recognized from the outset as presenting an extreme complexity that will inevitably advance pan passu with the advancing complexities of human experience. If, (...) then, simplification is impossible, the only alternative is to attempt to grasp the salient features and present these in their true relation, in the same way that an invading army seizes the principal bases of hostile territory.

Nous considérons la structure dans son rapport au temps : sous ce rapport, la structure est normative, et l’avenir aide à constituer le présent et le passé. Des exemples sont empruntés à l’embryologie et à la géologie. On explique pourquoi il est difficile de concevoir une structure cosmique spatio-temporelle, et comment le développement récent de la physique nous y aide ; dans cette physique, la notion de structure cosmique a un rôle éminent. Il en résulte que seules sont viables les (...) combinaisons qui sont dans La ligne historique de la nature. (shrink)

This paper argues that the Food and Drug Administration’s (FDA) policy for health and wellness apps is ethically problematic. Currently, the FDA does not regulate health and wellness apps that are not intended for medical use. As a result of this hands‐off policy, preventing harm to consumers is left primarily to developers and app marketplaces. We argue that the FDA’s duties to prevent harm and maintain accountability to the American public require that they play a much stronger role. We also (...) discuss concerns about efficiency and fostering innovation, and argue that while they should help shape FDA regulation of health and wellness apps, they do not justify complete absence of FDA involvement. -/- .

Descartes is always concerned about knowledge. However, the Galileo affair in 1633, the reactions to his Discourse on method, and later his need to reply to objections to his Meditations provoked crises in Descartes’s intellectual development the import of which has not been sufficiently recognized. These events are the major reasons why Descartes’s philosophical position concerning how we know and what we may know is radically different at the end of his life from what it was when he began. We (...) call this later position Descartes’s epistemic stance and contrast it with his earlier methodological, metaphysical realism. Yet Descartes’s epistemic views cannot be separated from other aspects of his work, for example, his views concerning God, causality, metaphysics, and the nature of science. A further meta-implication is that serious errors await any scholar who cites early Cartesian texts in support of late Cartesian positions, or who uses later texts in conjunction with early ones to support a reading of Descartes’s philosophy.Keywords: René Descartes; Nature; Motion; Method; Knowledge.
