Students of the Papal State are understandably inclined to concentrate on those geographical areas in central Italy, from the Campagna to Ravenna, that were to become the more or less permanent Papal State of modern history, even though everyone acknowledges that papal claims and the reality of papal control within this region fluctuated widely throughout the centuries. Tuscany, southern Italy, and Sicily were sometimes claimed by the popes but not ultimately incorporated into the Papal State, and these areas also receive (...) due attention from historians of the Papal State. But papal claims also extended to other areas less frequently discussed, among them Sardinia. (shrink)

AA 180& 'What has to be accepted, the given, is, so one could say, forms of life'. (PI p 226) Compare with Nietzsche. Nietzsche works out a theory of demoralisation. Understanding of the logic of language games makes a difference to those one will play. Compare Heraclitus. The form of life as the will, prana, that which determines whatever it is that is said or believed. The language is merely the medium. Yet this is not something to be set up (...) as a metaphysical theory. It is too particular, and any motive for demolishing it is likely to be sufficient to do so. There is no one way which is true over and above all others. To be able to talk on this plane we need a kind of higher logic. There are those who are desperate to discover the one explanation which is in a sense true. For them, an philosophy which focus on the nature of explanation itself, and thus dissolves the problem will appear irrelevant. Henceforth what is needed is not philosophical statements but logical tools. What we do with these tools is not the business of philosophy. 'one wonders what philosophy would have been like in Britain and the United States if it had not been for the accident of Wittgenstein, for he might not have been on the scene at all…. I meant that he became known to the world of philosophy through the very special circumstances of making a strong impression on Bertrand Russell, and being accepted into the world of philosophy through the bold initiative of Cambridge. Nature is wasteful, and if one wants to get something exceptionally good, one must take great risks about having a great deal that is simply wild. I am sure that both Russell and Cambridge were right to adopt such a policy. Cambridge is possibly the only university in the world that would have touched Wittgenstein at any price. Had it not been for Cambridge, and had it not been for Russell, - and some people would hold that he made an error of judgement- almost certainly nothing more would have been heard of Wittgenstein'..

The dissertation considers what is at stake when theoretical wonder ceases to be an originating affect for speculative thought and becomes, instead, a limiting concept for critical philosophy. It attempts to show that: wonder functions for its classical proponents in an entirely different context than that presupposed by the aesthetics of the sublime . This difference can be ascribed to the way in which the feeling of the sublime is operative in the overcoming of modern theodicy , whereas wonder is (...) an intimation of what Edward O. Wilson has recently called, the "consilient perspective" . Whereas, wonder suggests the beginnings of an overarching conceptual unity linking together mind and nature, the sublime, by contrast, is part of an ontology of freedom, in which our subjective capacity to withstand the blows of natural contingency without resorting to conceptual redescription or aesthetic totalization reveals the workings of an underlying "faculty of resistance." The resultant ambivalence of the sublime feeling is elucidated differently by Kant and Schiller, such that the former regards it as the cognitive lucidity resulting from the self-cancellation of the passions, whereas the latter views it as a function of the will, insofar as it suggests a subjective capacity to attend to things differently. Finally, it is suggested that the true source of sublimity in Kant and Schiller is the force of personality to lend unity and meaning to phenomena which would otherwise lack such. (shrink)

In prerevolutionary Europe, science in the broad sense of organized knowledge played a crucial role in the emergence of democracy and civic virtue. Medieval thinkers drew on Cicero, Aristotle, Roman law, the Christian tradition, and their own experiences to create systems of thought and institutions necessary for that emergence. Science in the modern sense of the exact physical sciences, however, made only limited and indirect contributions to that development.

BOOK REWEWS 309 down, Adam's "happy sin" sin was a fall "upward" that reversed involution and initiated the agonizing evolution of consciousness. Following Gnosticism, He- gel maintains that the divine "image" according to which humankind was created lies not "in the archaeological past but in the eschatological future" . The third moment of the trinitarian narrative, Spirit, involves the process whereby finite humankind attains "sonship" with the infinite divine. In Hegel's Christology, the "death of God" represents the temporary divine absence (...) needed for the emergence of divine presence in human community understood as Spirit. Far from constituting a once-and-for-all soteriological event, the life and death of Jesus opened the way for others to follow him to mystical union with God. For Hegel, mysticism involves not irrationality, but divine self-manifestation achieved in the highest form of knowing, Reason, available to the most illuminated members of the Christian community. Before closing his discussion of Spirit, O'Regan addresses the issues of 1) whether Hegel's theodicy fails to account adequately for the particularity of human suffering, and 2) whether divine self-realization as spirit in the human community provides an adequate account of the divine transcendence prefigured in the immanent trinity. Finally, O'Regan examines Spinoza and Schelling's influence on the "denarratizing operators" used by Hegel.. (shrink)

Odysseus has lived through many transformations since Homer commemorated him in the Odyssey. None of them, however, has made Homer obsolete. Both the Iliad and the Odyssey have been translated many times. By common consent of those competent to judge such matters, Robert Fagles has done a superb job with the Odyssey. Even before I read it, I heard it read by Ian McKellan. That was an eye-opener, or should I say ear-opener. It sounded as though that was the natural (...) way to come at it. The spaciousness, the contrast of tones alternating between casual, even rambling digression and the tightness of dramatic moments, the sense of intimacy a voice establishes—all these drew me into the poem and made me aware of new meanings, or forgotten relationships, that I would like to share. The Odyssey is so large and various that we need reminding of its riches. The only way to do this properly, it seems to me, is to travel along with Homer, hitting the highlights and commenting as I go. (shrink)
