Not long ago, under the influence of Michel Foucault, one spoke of the conjunction of knowledge and power, but in this post-truth era power appears singularly uninterested in knowledge, even as the supporters of Donald Trump claim that he alone of all politicians speaks the truth. This essay proposes to examine the relations of power and knowledge under the present populist assault. This analysis begins in the work of Claude Lefort, who spoke of the separation of knowledge and power in (...) democracy’s symbolic regime, and is then counterposed to Ernesto Laclau’s understanding of ‘populist reason’ in order to explore the present torsion of this relation to the point where power can appear not just separated from, but opposed to knowledge. It will be argued that it is less a question of post-truth than of different forms of truth with different truth claims, borne by different imperatives, and tied to different forms of representation – truth claims that can, in relation to each other, be indifferent, complementary, or conflictual. With this in mind, the essay asks: what is the relation of the people to truth? Do those who claim to represent the people seek possession of a different kind of truth? What is the relation of populism to ideology? And what is populism’s relation to ‘post-modernism’? (shrink)

This article is a longitudinal analysis of the relation between gendered labour divisions and new data processing technologies at the Dutch Central Bureau of Statistics. Following social-constructivist and evolutionary economic approaches, the authors hold that the relation between technology and work organization is a two-way process. This means that technology does not only affect the relations between men and women at work, but that these relations also influence technological choices. The proportional numbers of men and women on the labour market (...) and changing conceptions of which work is deemed appropriate for women have been important factors in the strongly varying extent to which women participated in office work. They have also been important factors in determining the course of technological development. Shortages of women on the labour market have even determined search heuristics for new technological solutions in specific directions. (shrink)

This book describes a program of research in computable structure theory. The goal is to find definability conditions corresponding to bounds on complexity which persist under isomorphism. The results apply to familiar kinds of structures (groups, fields, vector spaces, linear orderings Boolean algebras, Abelian p-groups, models of arithmetic). There are many interesting results already, but there are also many natural questions still to be answered. The book is self-contained in that it includes necessary background material from recursion theory (ordinal notations, (...) the hyperarithmetical hierarchy) and model theory (infinitary formulas, consistency properties).

In a discussion-note in Mind, Father P. M. Farrell, O.P., gave an account, in what he admitted to be an embarrassingly brief compass, of the Thomist doctrine concerning evil. There is one sentence in this discussion which at first glance appears paradoxical. Father Farrell has been arguing that a universe containing ‘corruptible good’ as well as incorruptible is better than one containing ‘incorruptible good’ only. He continues: ‘If, however, they are to manifest this corruptible good, they must be corruptible and (...) they must sometimes corrupt.’ The final words, despite Father Farrell's italics, strike one as expressing, not a self-evident truth, but a non sequitur. The fact that I am capable of committing murder does not entail that I will at some time commit it. It is not immediately obvious that a similar entailment holds in the case of corruption and corruptibility. (shrink)

The research investigates the role of leadership in the transformation of denominational structures towards a missional ecclesiology, and focusses on the Highveld Synod of the Dutch Reformed Church. It describes the missional journey of the denomination, and interprets the transformation. The theory of ‘complex leadership’ in complex systems is applied to the investigation of the impact of leadership on a denominational structure. The theory identifies three mechanisms used by leaders as enablers in emergent, self-organisation systems: Leaders disrupt existing patterns, they (...) encourage novelty, and they act as sensemakers. These insights are applied as a tool to interpret the missional transformation of a denomination. (shrink)

Deze korte studie biedt niet de zoveelste inleiding in het denken van Spinoza, maar doet verslag van de persoonlijke, vijfentwintig jaar durende zoektocht om de vaak moeilijke thema's van Spinoza onder de knie te krijgen. Om via Spinoza's filosofie meer te begrijpen van de wereld en van het eigen leven. Om de vreugde te ervaren die dit verbeterde inzicht, in oorzaken en gevolgen, en ook in de eigen beperktheid, ons biedt. Elk hoofdstuk gaat over een onderwerp dat de auteur bijzonder (...) aanspreekt. Bestaat er een levenswil, Spinoza's conatus, die mensen voort doet leven ook onder de meest bittere omstandigheden? Is kennis en inzicht gradueel van aard? Wat is het verschil tussen adequate en inadequate kennis van de oorzaken van ons handelen? Hoe ontwikkelt een machtsstaat zich tot een rechtsstaat? (shrink)

We extend results of Harizanov and Barker. For a relation R on a recursive structure /oA, we give conditions guaranteeing that the image of R in a recursive copy of /oA can be made to have arbitrary ∑α0 degree over Δα0. We give stronger conditions under which the image of R can be made ∑α0 degree as well. The degrees over Δα0 can be replaced by certain more general classes. We also generalize the Friedberg-Muchnik Theorem, giving conditions on a pair (...) of relations R and S under which the images of R and S can be made ∑α0 and independent over Δα0 in a recursive copy of /oA.
