This essay assesses the morality of Ukraine's use of drones to attack targets inside Russia. Following its invasion by Russian forces, Ukraine has had a just cause to wage a war of self-defense. However, its efforts to achieve that cause remain subject to moral limits. Even a state that has been unjustly attacked may not, for example, respond by deliberately targeting the attacking state's civilian population. To do so would violate the jus in bello principle of discrimination. The essay first (...) describes how drone technology has frequently enabled long-range strikes against Russian military assets as well as other targets inside cities. It then explains why it would be morally wrong for Ukraine to attack its enemy's population centers. First, Russian civilians are not liable to attack, and this nonliability is undiminished by the injustice of Russia's invasion or by any in bello wrongs committed by the Russian military. Second, attacking Russian cities with drones would arguably achieve little or no self-defensive benefit for Ukraine, and it could even be counterproductive. (shrink)

Es ist bekannt, daß Husserl Fichtes theoretischer Philosophie keine gute Seite abgewinnen konnte. In den 1917 vor Kriegsheimkehrern gehaltenen und 1918 wiederholten Vorträgen über Fichte spricht Husserl von »abstrusen Konstruktionen«, die in der Wissenschaftslehre Fichtes zu finden seien. Nichtsdestotrotz kann man sehen, daß beide Ansätze mehr als bloße Strukturanalogien aufweisen. Es wurde - wenn auch nicht häufig - darauf hingewiesen, daß sachliche Verweise beider Ansätze aufeinander möglich sind. Die Berührungspunkte in der praktischen Philosophie dagegen fallen eher ins Auge. In seinen (...) Vorträgen orientiert sich Husserl insbesondere an Fichtes populären und religionsphilosophischen Schriften und es ist inzwischen bekannt, daß sich Husserl in den 20er Jahren vermehrt der praktischen Philosophie im Sinne Fichtes zuwendet, über deren Verhältnis zu der seinen er in einem Brief an Adolf Grimme meint, »daß die religions-philosophischen Perspektiven, die mir die Phänomenologie eröffnete, überraschend nahe Beziehung zu Fichtes späterer Gotteslehre zeigen«. Ich möchte mich an dieser Stelle auf den theoretischen Zugang konzentrieren und dabei speziell den Begriff der Affektion bei Fichte und Husserl näher untersuchen. (shrink)

Mathematicians often say that their theorems, proofs, and theories can be beautiful. They say mathematics can be like art. They know how to move creatively and freely in their domains. But ordinary people usually cannot do this and do not share this view. They often have unpleasant memories from school and do not have this experience of freedom and creativity in doing mathematics. I myself have been a mathematician, and I wish to highlight some of the creative aspects in doing (...) mathematics. I always had the feeling that there is much freedom in mathematics and that one can do as one pleases as long as one avoids contradictions (and one can even live with contradictions for a while). In mathematics one only needs to define something and there it is! Just imagine it, and it immediately exists. Where else, besides fiction, does one have such power? --- This essay has three parts. In the first, I lay out some historical facts and views that I will need later. Second, I insert an interlude with Kant, pointing out some of his claims and insights in aesthetics, and some aspects in mathematics that I think he overlooked or underestimated. Third, I will bring out some aspects of higher mathematics that I will show are similar to art. These aspects are in the doing and creating of mathematics, not in the finished theories. They are usually not found in textbooks. I want to show that a researcher in mathematics is like a painter or composer, exploring and creating. To see this, one has to adopt a first-person perspective. In this way I will show that aesthetics plays a role and leaves its traces also in mathematics. (shrink)

Resumen En el Leviatán Hobbes implementa la ley de naturaleza como la condición de posibilidad del desarrollo epistemológico que convierte al animal en humano, en el estado de naturaleza. De acuerdo con esta fórmula, la moral se desarrolla cuando los hombres empiezan a comportarse de acuerdo con el contenido no explícito de las leyes de naturaleza, comportamiento posibilitado por su sujeción a un hombre fuerte, quien tiene la función moral de administrar justicia. Esta doble función moral de las leyes de (...) naturaleza entre quien manda y quien obedece implica una experiencia de la justicia como comunicación de postulados racionales compartidos que condicionan el libre accionar de los hombres, manteniéndolos unidos en el tiempo.In the Leviathan, Hobbes employs the law of nature as the condition of possibility of the epistemological development that transforms the animal into a human in the state of nature. According to this formula, morality develops when men behave according to the non-explicit content of the laws of nature, behavior enabled by their subjection to a strong man who has the moral function of administrating justice. The moral function of the laws of nature is double, those who rule and those who obey, and implies an experience of justice as communication of shared rational postulates that conditions the free actions of men, keeping them united in time.

Ainsi pervertie, la science finit par dériver vers un spiritualisme malsain propre à créer la confusion entre physique des astres et métaphysique.

In den Philosophischen Brocken kritisiert Kierkegaard die sokratische Präexistenzlehre wegen ihrer nihilistischen Konsequenzen für die Zeitlichkeit: Das geschichtliche Dasein des Menschen wäre überflüssig, wenn er a priori bereits vollendet wäre. Weil Kierkegaard in seiner christlichen Argumentation dennoch nicht umhin kann, selbst ein Analogon zum vorgeburtlichen Sein der Seele bei Platon vorauszusetzen, wendet er in der religiösen Schrift Die Krankheit zum Tode einen sophistischen Trick an, mit dessen Hilfe er die Präexistenzimplikation aus dem Bewusstsein des Lesers verdrängen will.

The philosophical parting of the ways between Heidegger’s Fundamental ontology and the Philosophical anthropology of Plessner is well known. Today, however, after the publication of the »Schwarze Hefte«, new aspects of their differences come to light. Accordingly, this article focusses on the purpose of death discussed in »Die Stufen des Organischen« as a genuine thought Plessner inscribed into 20th century philosophy. It argues that the most peculiar difference is to be found in Plessner’s view on death not as a simple (...) element of life but as an external phe- nomenon. In contrast to Plessner, Heidegger’s »Schwarze Hefte« seem to present more of an eschatology than a systematical approach to human self and world. (shrink)

Prémisses Notre sujet est ce moment qui suit le conflit, que l’on nomme le plus souvent l’après-guerre, perçu comme moment problématique, comme processus toujours inachevé. Voilà pourquoi nous avons préféré renvoyer, par notre titre, non pas à un objet défini et délimité par un substantif (« l’après-guerre ») mais, justement, à un questionnement lié à un moment sans frontières avérées, à une « qualité des temps », comme aurait dit Machiavel. Après la guerre... donc. Nous n’entendons pas en ef...
