'To think often, and never to retain it so much as one moment, is a very useless sort of thinking' In An Essay concerning Human Understanding, John Locke sets out his theory of knowledge and how we acquire it. Eschewing doctrines of innate principles and ideas, Locke shows how all our ideas, even the most abstract and complex, are grounded in human experience and attained by sensation of external things or reflection upon our own mental activities. A thorough examination of (...) the communication of ideas through language and the conventions of taking words as signs of ideas paves the way for his penetrating critique of the limitations of ideas and the extent of our knowledge of ourselves, the world, God, and morals. Locke's masterpiece laid the foundation of British empiricism and is of enduring interest to anyone exploring the development of philosophical thought. This sensitive abridgement uses P. H. Nidditch's authoritative text, and together with an illuminating introduction and other features, makes Locke's arguments more accessible. (shrink)

Lately, a number of philosophers have argued that agents can be more and less active in the production of their own actions. Some actions—principally reflective, deliberative ones—are said to involve agential activity; other actions—principally unreflective, non-deliberative ones—are said to be brought about in a more passive fashion. In this essay, I critique these claims. I show that philosophers employing the notion of agential activity have relied on one or more of the following claims, which have not been clearly distinguished in (...) the literature: (1) that choice causes action, (2) that motives do not determine choice, and (3) that reflective deliberation suspends the effects of motives. These claims are closely related, and are often conflated in the literature. However, I argue that they are importantly distinct. I explicate and assess each of these claims, arguing that while there are precisifications of the first and second claims that render them true, there are philosophical arguments and results from empirical psychology indicating that the third claim is false. Moreover, I argue that the third claim is the crucial one; its truth is necessary in order to support the idea that reflective agency is paradigmatically active. As a result, the traditional accounts of agential activity must be rejected. I close by suggesting a new model of agential activity. (shrink)
