There is a tendency to prune the record of restrictions on the freedom of thought and expression in fifth-century Athens. K. J. Dover has demonstrated that many of the stories of attacks on intellectuals rest on little more than flimsy speculation. Similarly there has been a reluctance to accept the historicity of the several restrictions on comedy recorded by scholiasts. Thus, for example, H. B. Mattingly has expressed doubts about Morychides' decree, and S. Halliwell has rejected Antimachus' decree as a (...) fiction and has adopted an agnostic attitude towards Syracosius' decree. But one cannot sweep all the references aside as fallacious inferences. This short paper looks first at the evidence that Cleon initiated a legal action against Aristophanes after the production of the The Babylonians, in the light of what the Old Oligarch wrote about curbs on comedians. Secondly, the historicity of Syracosius' decree will be tested by an attempt to define its nature and purpose in its political context. This exercise will show that circumstantial evidence adduced against the historicity of the decree has no compelling force. (shrink)

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)
