Die vorliegende Arbeit untersucht Möglichkeiten und Grenzen der Verwendung von einfachen konnektionistischen Systemen als Modelle für den Erwerb und die Repräsentation von Wissen über zeitdiskrete lineare dynamische Systeme in der Kognitionspsychologie. Ein ausgewähltes dynamisches System namens SINUS wird in Form eines „pattern associators“ repräsentiert und dessen Lernverhalten untersucht. Es wird versucht, daraus Annahmen über den Wissenserwerb von Probanden im Umgang mit solchen dynamischen Systemen abzuleiten, um insbesondere Hinweise darauf zu erhalten, was „gute“ von „schlechten“ Probanden unterscheidet. Ein weiterer hier betrachteter (...) Aspekt ist die Steuerung eines dynamischen Systems in einen vorgegebenen Zielzustand, der unter Beibehaltung des konnektionistischen Modells durch einen variierten Lernalgorithmus modelliert wird. Die abschließende Diskussion geht auf die Bedeutung der Modellierung für die kognitionspsychologische Theorienbildung ein. (shrink)

It is commonly believed that considering nature different from us, human beings (qua rational, cultural, religious and social actors), is detrimental to our engagement for the preservation of nature. An obvious example is animal rights, a deep concern for all living beings, including non-human living creatures, which is understandable only if we approach nature, without fearing it, as something which should remain outside of our true home. “Walking with the earth” aims at questioning any similar preconceptions in the wide sense, (...) including allegoric-poetic contributions. We invited 14 authors from 4 continents to express all sorts of ways of saying why caring is so important, why togetherness, being-with each others, as a spiritual but also embodied ethics is important in a divided world.

Apūrvaṃ vyākaraṇakauśalam ity āstām: “let it remain an example of unprecedented grammatical skill” — thus sarcastically remarks the Dvaitin commentator Jayatīrtha on Śaṅkarācārya’s sleight of hand to turn written saṃbhūti into asaṃbhūti at one of the many difficult turns the Īśa Upaniṣad has in store for his strictly monistic stance. But Jayatīrtha’s own master Madhva is renowned in his own right for his “unprecedented skill” in conjuring up whole unattested smṛti passages to corroborate his interpretations. Indeed, more specimens of “unprecedented (...) skill” are displayed in turn by each of the great bhāṣyakāras of the three conflicting schools — Advaita, Dvaita and Viśiṣṭādvaita — on this Upaniṣad, which on account of its extreme pithiness is singularly suited to demonstrate the length dārśanikas are willing to go to make an authoritative text square each with his own preconceived philosophical outlook. A most telling example of the preemptive force of world-views on actual theoretical practice in the Indian context. (shrink)

Book Review of Kevin Aho's One Beat More: Existentialism and the Gift of Mortality (Polity, 2022).

"Heidegger on Being a Sexed or Gendered Human Being" is my contribution to a Symposium dedicated to the topic "Heidegger's idea of the human being." Editor Scott Campbell requested that participants (myself, Kevin Aho, Jesús Adrián Escudero, Tricia Glazebrook, Róisín Lally, and Iain Thomson) write a 1000 word statement addressing this question. Participants read each others contributions and submitted a 500 word response. This is my original statement.

In “Melancholia, temporal disruption, and the torment of being both unable to live and unable to die”, I discuss the way in which the temporal desynchronization of melancholia can disrupt the melancholic’s relation to their own death and, on a Heideggerian interpretation, the meaning and significance of their life. In their thoughtful commentaries, Kevin Aho and Gareth Owen draw out some important points for further elaboration and clarification, the most pressing of which invoke Heidegger’s interpretation of time and the radical (...) temporalities of fundamental attunements. As Aho anticipates, this is the conception of time that underpins my interpretation of melancholia and, because this is important... (shrink)
