Internalists hold that all reasons derive from existing motivations. They also hold that agents act irrationally when they fail to act on the strongest reasons they have. Emotions can make one act irrationally. But depression as an emotion tends to remove the motivation to act at the same time as it causes irrational inaction. If depression can cause irrationality, then the reasons to act must remain. Hence the internalist must explain how reasons can remain if depression removes motivation. This paper (...) does so by arguing that the cognitive, evaluative aspect of motivation remains when the dispositional and affective aspects are removed. (shrink)

Paul Churchland's philosophical work enjoys an increasing popularity. His imaginative papers on cognitive science and the philosophy of psychology are widely discussed. Scientific Realism and the Plasticity of Mind (1979), his major book, is an important contribution to the debate on realism. Churchland provides us with the intellectual tools for constructing a unified scientific Weltanschauung. His network theory of language implies a provocative view of the relation between science and common sense. This paper contains a critical examination of Churchland's network (...) theory of language, which is the foundation of his philosophy. It is argued that the network theory should be seen as deriving its point from traditional empiricism. The network theory enables the empiricist to resist the phenomenalistic temptations inherent in his position, and to build a realist philosophy on the basis of the representative theory of perception. This interpretation is confirmed by the fact that the representative theory is presupposed by Churchland's main argument in favour of the network view. Churchland tends to conceive of himself as a naturalistic epistemologist. But the philosophical faction to which Churchland belongs is rather that of modern neo?Kantianism. (shrink)
