Plotinus (204-70) is the founder of Neoplatonism and its most significant thinker. He shaped late antique philosophy and significantly influenced the entire metaphysical tradition of the Middle Ages, Renaissance, and German Idealism. In this volume, Jens Halfwassen presents Plotinus' life and work, as well as the most important aspects of his historical influence. Issues of key importance for the Neoplatonists-such as the interaction between Being and Thought, the ascent of the soul, and the interpretation of Plato's theory of principles-are (...) explained in detail in the course of outlining the Neoplatonic metaphysical system. The introduction outlines Halfwassen's significant contribution to the study of Plotinus, paying particular attention to the differences between the current German and Anglophone approaches to the Platonic tradition.

English summary: The connection between the soul and the material world played an important role in Neoplatonic thought. Generally, this connection prompted questions like: How should one think about the effect of the soul on the material and conversely, of matter on the soul? How is evil to be understood? Does the soul beget evil through itself or is it drawn to evil from the matter? How is the connection between the Logos, as the principle structure of the soul, as (...) well as the principle means by which the material world is organized, understandable? And what role does the intellect play in the fabric of matter and soul, which Plato already confirmed as a divine thought? These and other questions are followed up from a historical-systematic perspective in the essays collected in this volume, contributed by internationally renowned scholars of Neoplatonism. German description: Die Beziehung zwischen Seele und Materie spielt eine bedeutende Rolle im Denken des Neuplatonismus. Allerdings wirft diese Beziehung eine ganze Reihe von Fragen auf: Wie muss die Wirkung der Seele auf die Materie und umgekehrt der Materie auf die Seele gedacht werden? Wie ist das Bose zu verstehen? Bringt die Seele das Bose durch sich selbst hervor oder wird sie von der Materie zum Bosen angezogen? Wie lasst sich der Zusammenhang begreifen, durch den der Logos als das Strukturprinzip der Seele die Welt ordnet? Und welche Rolle spielt im Gefuge von Materie und Seele der Geist, den bereits Platon als ein gottliches Denken bestimmt hat? Diesen und anderen Fragen wird in den hier versammelten Aufsatzen aus historisch-systematischer Perspektive von international renommierten Neuplatonismusforschern nachgegangen. (shrink)

Der Vorsokratiker Xenophanes von Kolophon aus dem 6. vorchristlichen Jahrhundert gilt als der Begründer eines philosophischen Monotheismus, der unabhängig vom Monotheismus der hebräischen Bibel aus dem Denken entstand. Aber war Xenophanes wirklich Monotheist? Diese Frage soll im Folgenden beantwortet werden. Dazu ist aber vorab der Begriff des ‚Monotheismus‘zu klären.

Aufstieg zum Einen - das ist das Zentrum der Philosophie Plotins und des von ihm ausgehenden Neuplatonismus. Dass solcher Aufstieg zum Einen aber auch schon bei Platon eine zentrale Rolle spielt, gehört zu den wichtigsten Einsichten der neueren Platonforschung. Das vorliegende Buch zieht daraus die Konsequenz und bestimmt das Verhältnis zwischen Platon und dem Neuplatonismus neu. Es verbindet die erste umfassende Darstellung von Plotins Theorie des Absoluten mit einer Rekonstruktion von Platons Henologie. Dabei arbeitet es die enge Verbindung beider heraus (...) und macht zugleich die bleibende philosophische Relevanz des Themas deutlich. (shrink)

Consequence is at the heart of logic, and an account of consequence offers a vital tool in the evaluation of arguments. This text presents what the authors term as 'logical pluralism' arguing that the notion of logical consequence doesn't pin down one deductive consequence relation; it allows for many of them.

One of the main problems of Plato's unwritten doctrine has to do with whether his theory of principles has a strictly dualistic or rather a more monistic character. The thesis of this essay is that Plato combines monism and dualism in a particular fashion. Both the dialogues and the testimony of the unwritten doctrine reveal that in Plato's metaphysics the One is the genuinely absolute principle; Plato's second principle, the Many, is not a second absolute - otherwise it would dissolve (...) the very concept of the absolute. Instead, Plato conceives the principle of multiplicity itself as a unity, therefore as in some - in any event ineffable - way as being derived or having emanated from the absolute One. The One itself is wholly transcendent and thus ineffable, knowable neither by reason nor by intellective intuition. Nonetheless, being and knowledge are constituted by the coordination of the One and the Many, for which reason the latter is a principle. Hence, Plato's metaphysics combine a monistic ascent to the absolute with a dualistic derivation of being, a combination made necessary because the One transcends not only all being, but also all knowledge.

What happens when someone acts? A familiar answer goes like this. There is something that the agent wants, and there is an action that he believes conducive to its attainment. His desire for the end, and his belief in the action as a means, justify taking the action, and they jointly cause an intention to take it, which in turn causes the corresponding movements of the agent's body. I think that the standard story is flawed in several respects. The flaw (...) that will concern me in this paper is that the story fails to include an agent-or, more precisely, fails to cast the agent in his proper role. (shrink)

Aristotle construed metaphysics primarily in terms of ontology, whereas Plato had developed a different approach to the philosophy of principles. The main task of the metaphysical theory of principles is the quest for the absolute. For Plato, however, the absolute is the one; and this idea – most influentially advocated by Plotinus – is the foundation of a tradition that construes metaphysics mainly in terms of henology. The central aspects of this doctrine are the idea of the transcendence of the (...) absolute one, the perspective of negative theology, and – in Plotinus – a genuinely philosophical kind of mysticism.

Transcendent thinking as a basic feature of metaphysical philosophy has always claimed to be more than a mere cognition of reality in terms of its phenomena. Transcendent philosophy intends to consider reality from the perspective of a fundamental ground transcending the reality ordered by that ground. Plato, who created the very notion of philosophy, described the love of wisdom as an ascent to the absolutely transcendent One and Good, which he believed to be the principle and source of all being. (...) Plotinus both took over and renewed the Platonic view of philosophy as transcendent thinking. In his view, the philosopher can only relate to that principle which transcends even thinking itself by practicing a mystical philosophy and thereby leaving behind his own dialectical thinking.

Der ontologische Gottesbeweis, den zuerst Anselm von Canterbury in seinem Proslogion entwickelt, setzt einen spezifischen Begriff von Sein als Fülle voraus, ohne den er unverständlich bleibt. Dieser Seinsbegriff entstammt dem antiken Platonismus. Erst Platon faßt den Begriff des Seins so, daß er in einem ontologischen Komparativ wahres oder vollkommenes Sein vom uneigentlichen Sein unterscheidet. Plotin entwickelt daraus einen Begriff vom Sein als absoluter Fülle, in dem die beiden Bedeutungen des vollkommenen und des notwendigen Seins, die, wie Henrich gezeigt hat, für (...) den ontologischen Gottesbeweis maßgeblich sind, auf konsistente Weise vereinigt sind. Bei Plotin ist dieses absolute Sein der sich selbst als Inbegriff der Ideen denkende Nous, von dem er das Absolute als Überseiendes unterscheidet. Boethius vermittelt Plotins Begriff des absoluten Seins an Anselm, und zwar als Begriff von Gott, d.h. so gefaßt, daß das vollkommene Sein zugleich das Absolute ist. Index dieses Seinsbegriffs ist der bei Plotin, Boethius und Anselm jeweils übereinstimmende Begriff der Ewigkeit als teillos vollendeter Einheit und Ganzheit. (shrink)

Abstract I argue that meaning in life is importantly influenced by bioloical ties. More specifically, I maintain that knowing one's relatives and especially one's parents provides a kind of self-knowledge that is of irreplaceable value in the life-task of identity formation. These claims lead me to the conclusion that it is immoral to create children with the intention that they be alienated from their bioloical relatives?for example, by donor conception.

Retributive theories of punishment argue that punishing a criminal for a crime she committed is sufficient reason for a justified and morally permissible punishment. But what about when the state gets lucky in its decision to punish? I argue that retributive theories of punishment are subject to “Gettier” style cases from epistemology. Such cases demonstrate that the state needs more than to just get lucky, and as these retributive theories of punishment stand, there is no anti-luck condition. I’ll argue that (...) Gettier-style cases demonstrate an impermissible instance of punishment, even though they meet the conditions of retributive theories of punishment. Retributive theories are, therefore, too weak. The safety condition from epistemology provides the anti-luck condition needed for permissible punishment. I argue that two forms of retributivism, rights-forfeiture and what I call standard retributivism, are both subject to Gettier-style cases. Unlike the literature on standards of proof, this paper argues that safety is a condition on punishment itself, i.e., in all nearby possible worlds, the accuser must correctly accuse the convicted for the crime they actually committed.

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

J.L. Schellenberg offers a path to a new kind of religious outlook. Reflection on our early stage in the evolutionary process leads to skepticism about religion, but also offers a new answer to the problem of faith and reason, and the possibility of a new, evolutionary form of religion.
