The computer is a relatively new invention in the history of man. It has found application in many sectors, and will undoubtedly influence our society. As we shall show, however, the computer is linked to a chain of development that started 10,000 years ago, when a society of hunters and gatherers changed into an agricultural society. The computer is completely dependent on this development towards a more and more formalized society.

This paper aims to explain the distinction between syllogisms and subsyllogisms in Stoic logic. Subsyllogisms replace at least one premise in a syllogism with a premise that is, according to Galen and Alexander, equipollent to the respective syllogistic premise. This equipollence is not synonymy of meaning between two linguistic expressions, but obtains between two propositions when they are true or false by the same standard. Subsyllogistic premises are simple propositions that are equipollent to the non-simple premises of the respective syllogisms. (...) For subsyllogistic premises that replace syllogistic premises consist of predicates combining with cases rather than of connectives or negations governing propositions. Because of this difference in their premises, subsyllogisms have a different logical form than syllogisms and are not formally valid. (shrink)

At APr 2.4 57a36–13, Aristotle presents a notorious reductio argument in which he derives the claim ‘If B is not large, B is large’ and calls that result impossible. Aristotle is thus committed to some form of connexivity and this paper argues that his commitment is to a strong form of connexivity which excludes even cases in which ‘B is large’ is necessary. It is further argued that Aristotle’s view of connexivity is best understood as arising from his analysis of (...) affirmation and negation in terms of combination and separation: a proposition that separates two terms cannot entail a proposition that combines the same two terms. In order to motivate this account of connexivity, this paper interprets Aristotle as emphasising the predicative structure, especially the copulae, of the argument’s component propositions. The arguments for this are based on a consideration of the larger context of APr 2.2–4. A reconstruction of the argument using propositional variables does not fully capture Aristotle’s intentions.

My paper focuses on two different ways of relating textuality and asceticism in late medieval vernacular texts. The first part investigates various textual representations of the polyvalent ascetic biography of Elizabeth of Hungary (most of them based on the ‘Vita S. Elyzabeth’ by Dietrich von Apolda), and observes that Elizabeth’s rather modern, worldly ascetic practices did not inhibit monastic reception of their hagiographic representations in the vernacular. Nonetheless, at least one passage of the different versions of the ‘Vita’ questions, in (...) a more or less pronounced manner, the very possibility of representing ascetism. Rutebeuf’s 13th-century French version puts it most clearly: It is not the movement of lips and teeth that leads to salvation, but true compunction. Subsequently, the second part discusses a related question raised by a 14th-century Rhenish Franconian confessional handbook: Does textual ascetism have to be encoded via linguistic form? (shrink)

The theory of sign and proof is an essential component of Stoic epistemology. This book examines the fragmentary evidence from Sextus Empiricus and sheds light on the two aspects that characterise signs and proofs: the logical relation that holds between a sign and that which it signifies and an additional epistemic relation that is called revelation. All signs feature in conditionals that are true in virtue of the strong modal account of conditionals that the Stoics developed. This modal account is (...) one aspect that makes it possible to gain certain knowledge of that which is signified. But signs and proofs must also reveal that which they signify to produce knowledge. This requirement is fulfilled when an inference proceeds from premises that are justified through knowledge of the causal relation in virtue of which the premises are true. (shrink)

We show how to construct ordinals up to the small Veblen ordinal in a constructive way and discuss some of the problems trying to go beyond them.

Self-injurious behavior is associated with diverse psychiatric conditions. Sometimes, SIB is the most dominant symptom, severely restricting the psychosocial functioning and quality of life of the patients and inhibiting appropriate patient care. In severe cases, it can lead to permanent physical injuries or even death. Primary therapy consists of medical treatment and if implementable, behavioral therapy. For patients with severe SIB refractory to conventional therapy, neuromodulation can be considered as a last recourse. In scientific literature, several successful lesioning and deep (...) brain stimulation targets have been described that can indicate a common underlying neuronal pathway. The objectives of this study were to evaluate the short- and long-term clinical outcome of patients with severe, therapy refractory SIB who underwent DBS with diverse underlying psychiatric disorders and to correlate these outcomes with the activated connectivity networks. We retrospectively analyzed 10 patients with SIB who underwent DBS surgery with diverse psychiatric conditions including autism spectrum disorder, organic personality disorder after hypoxic or traumatic brain injury or Tourette syndrome. DBS targets were chosen according to the underlying disorder, patients were either stimulated in the nucleus accumbens, amygdala, posterior hypothalamus, medial thalamus or ventrolateral thalamus. Clinical outcome was measured 6 months after surgery and at long-term follow-up after 10 or more years using the Early Rehabilitation Barthel index and time of restraint. Connectivity patterns were analyzed using normative connectome. Based on previous literature the orbitofrontal cortex, superior frontal gyrus, the anterior cingulate cortex, the amygdala and the hippocampus were chosen as regions of interest. This analysis showed a significant improvement in the functionality of the patients with DBS in the short- and long-term follow-up. Good clinical outcome correlated with higher connectivity to the amygdala and hippocampus. These findings may suggest a common pathway, which can be relevant when planning a surgical procedure in patients with SIB. (shrink)

In der Zeit nach K. C. F. Krauses Tod wurde in der Philosophie darum gerungen, die umwalzende Kraft des deutschen Idealismus zeitgemass zu retten. In diesem Zusammenhang spielte Krause eine wichtige Rolle. Sein System wurde verstarkt rezipiert - in Lehrbuchern, in Ruges, Schweglers und Noacks Jahrbuchern, aber auch beispielsweise in I. H. Fichtes Zeitschrift fur Philosophie. Weiterhin aufschlussreich fur die Wirkung Krauses ist die von Urena beleuchtete Krause'sche Position zum Deutschkatholizismus im Gegensatz etwa zu Gervinus, Bayrhoffer oder Vischer. Uberdies zeigt (...) der Band die Rezeption der Krause'schen Staatslehre in der Tubinger Volkswirtschaftslehre auf. Schliesslich zeigt Urena, inwiefern sich Krause als einer der ersten fur die Gleichberechtigung der Frau eingesetzt hat - sowohl in der Theorie als auch in der Praxis. Das Buch zeichnet eine beeindruckende Wirkungsgeschichte nach, wodurch Krauses Einfluss auf die Philosophie des 19. Jahrhunderts deutlich wird. (shrink)
