Seeing Through the Fumes: Technology and Asymmetry in the Anthropocene
Zwier, Jochem ; Blok, Vincent - \ 2019
Human Studies (2019). - ISSN 0163-8548
Anthropocene - Asymmetry - Bataille - Cybernetics - Earth - Heidegger

This paper offers a twofold ontological conceptualization of technology in the Anthropocene. On the one hand, we aim to show how the Anthropocene occasions an experience of our inescapable inclusion in the technological structuring of reality that Martin Heidegger associates with cybernetics. On the other hand, by confronting Heidegger’s thought on technology with Georges Bataille’s consideration of technological existence as economic and averted existence, we will criticize Heidegger’s account by arguing that notwithstanding its inescapable inclusion in cybernetics, technology in the Anthropocene itself fosters an experience of what remains excluded. We conclude by indicating how such an experience is relevant for contemporary philosophical investigation of technology.

Saving Earth : Encountering Heidegger's Philosophy of Technology in the Anthropocene
Zwier, J. ; Blok, V. - \ 2017
Techné: Research in Philosophy and Technology 21 (2017)2/3. - ISSN 1091-8264 - p. 222 - 242.
In this paper, we argue that the Anthropocene is relevant for philosophy of technology because it makes us sensitive to the ontological dimension of contemporary technology. In §1, we show how the Anthropocene has ontological status insofar as the Anthropocenic world appears as managerial resource to us as managers of our planetary oikos. Next, we confront this interpretation of the Anthropocene with Heidegger’s notion of “Enframing” to suggest that the former offers a concrete experience of Heidegger’s abstract, notoriously difficult, and allegedly totalitarian concept (§2). In consequence, technology in the Anthropocene cannot be limited to the ontic domain of artefacts, but must be acknowledged to concern the whole of Being. This also indicates how the Anthropocene has a technical origin in an ontological sense, which is taken to imply that the issue of human responsibility must be primarily understood in terms of responsivity. In the final section (§3), we show how the Anthropocene is ambiguous insofar as it both accords and discords with what Heidegger calls the “danger” of technology. In light of this ambiguity, the Earth gains ontic-ontological status, and we therefore argue that Heidegger’s unidirectional consideration concerning the relation between being and beings must be reoriented. We conclude that the Anthropocene entails that Heidegger’s consideration of the “saving power” of technology as well as the comportment of “releasement” must become Earthbound, thereby introducing us to a saving Earth.
“Perceelspecifiek bemesten”
Vegte, Zwier van der - \ 2017
Al een aantal jaren wordt op KTC De Marke samen met ForFarmers de dag ‘Melkers van Morgen’ georganiseerd. Op deze dag kunnen veehouders en andere geïnteresseerden diverse workshops volgen, gewassen en demonstratievelden bekijken en leren over nieuwe innovaties op gebied van ruwvoerteelt. In de onderzoeken staat optimaliseren van efficiënte ruwvoerteelt met minimale belasting van milieu centraal. Vanuit de Kenniswerkplaats Achterhoek (KWPA) en de 4Groen-scholen is het idee ontstaan om dit jaar samen met ForFarmers en KTC De Marke een ‘Melkers van Morgen’ speciaal voor docenten veehouderij in het noordoosten van Nederland te organiseren. Ondanks de lastige periode in het onderwijs kwamen er ruim 50 docenten veehouderij op 4 juli 2017 naar deze dag.
Phenomenology and the Empirical Turn : a Phenomenological Analysis of Postphenomenology
Zwier, Jochem ; Blok, Vincent ; Lemmens, Pieter - \ 2016
Philosophy & Technology 29 (2016)4. - ISSN 2210-5433 - p. 313 - 333.
Empirical turn - Enframing - Heidegger - Postphenomenology - Theoretical attitude

This paper provides a phenomenological analysis of postphenomenological philosophy of technology. While acknowledging that the results of its analyses are to be recognized as original, insightful, and valuable, we will argue that in its execution of the empirical turn, postphenomenology forfeits a phenomenological dimension of questioning. By contrasting the postphenomenological method with Heidegger’s understanding of phenomenology as developed in his early Freiburg lectures and in Being and Time, we will show how the postphenomenological method must be understood as mediation theory, which adheres to what Heidegger calls the theoretical attitude. This leaves undiscussed how mediation theory about ontic beings (i.e.,technologies) involves a specific ontological mode of relating to beings, whereas consideration of this mode is precisely the concern of phenomenology. This ontological dimension is important to consider, since we will argue that postphenomenology is unwittingly technically mediated in an ontological way. The upshot of this is that in its dismissal of Heidegger’s questioning of technology as belonging to “classical philosophy of technology,” postphenomenology implicitly adheres to what Heidegger calls technology as Enframing. We argue that postphenomenology overlooks its own adherence to the theoretical attitude and ultimately to Enframing, and we will conclude with calling for a phenomenological questioning of the dimension that postphenomenology presently leaves unthought, meaning that we will develop a plea for a rehabilitation of the ontological dimension in the philosophy of technology.

Evidence from pyrosequencing indicates that natural variation in animal personality is associated with DRD4 DNA methylation

behaviour - birds - DNA methylation - epigenetics - personality

Personality traits are heritable and respond to natural selection, but are at the same time influenced by the ontogenetic environment. Epigenetic effects, such as DNA methylation, have been proposed as a key mechanism to control personality variation. However, to date little is known about the contribution of epigenetic effects to natural variation in behaviour. Here, we show that great tit (Parus major) lines artificially selected for divergent exploratory behaviour for four generations differ in their DNA methylation levels at the dopamine receptor D4 (DRD4) gene. This D4 receptor is statistically associated with personality traits in both humans and nonhuman animals, including the great tit. Previous work in this songbird failed to detect functional genetic polymorphisms within DRD4 that could account for the gene-trait association. However, our observation supports the idea that DRD4 is functionally involved in exploratory behaviour but that its effects are mediated by DNA methylation. While the exact mechanism underlying the transgenerational consistency of DRD4 methylation remains to be elucidated, this study shows that epigenetic mechanisms are involved in shaping natural variation in personality traits. We outline how this first finding provides a basis for investigating the epigenetic contribution to personality traits in natural systems and its subsequent role for understanding the ecology and evolution of behavioural consistency.

Contain all the individual methylation levels per CpG position for assays A-D. Each tab ($data_$assay_$tissuetype) contains the results from one pyrosequence run and one type of tissue (blood or brain). The columns indicate: SampleID: bird sample Note: EEB score, F is Fast exploring, S is Slow exploring Pos. 1 Meth%: Methylation percentage for CpG position 1 in assayB Pos. 2 Meth%: Methylation percentage for CpG position 2 in assayB Etc. Cell colours indicate quality scores In green: highly reliable methylation scores In yellow: reliable methylation scores In pink: unreliable methylation scores (not used in downstream analyses) SampleID with *_replicate indicates that the DNA sample with this number was used in duplo on this plate for within assay analysis.
The Ideal of a Zero-Waste Humanity: Philosophical Reflections on the demand for a Bio-Based Economy
Zwier, J. ; Blok, V. ; Lemmens, P. ; Geerts, R.J. - \ 2015
Journal of Agricultural and Environmental Ethics 28 (2015)2. - ISSN 1187-7863 - p. 353 - 374.
In this paper we inquire into the fundamental assumptions that underpin the ideal of the Bio-Based Economy (BBE) as it is currently developed . By interpreting the BBE from the philosophical perspective on economy developed by Georges Bataille, we demonstrate how the BBE is fully premised on a thinking of scarcity. As a result, the BBE exclusively frames economic problems in terms of efficient production, endeavoring to exclude a thinking of abundance and wastefulness. Our hypothesis is that this not only entails a number of internal tensions and inconsistencies with regard to the ideal of BBE, but ultimately undermines the ideal itself, by pushing purported regenerativity into a cataclysmic and terminal discharge. We here point to the strategies that the BBE employs in this exclusion, the fundamental assumptions regarding the relation between energy and economy that underpin this endeavor, as well as to the resulting inconsistencies and their catastrophic consequences. We finally argue for the introduction of the presently excluded question of abundance and wastefulness and explore the implications of such a question for the ideal of a zero-waste humanity

Alternatief voedergewas nog weinig interessant

Alternatieve voedergewassen kunnen als krachtvoervervanger dienen of als goedkope aanvullende eiwitbron. ASG-onderzoeker Herman van Schooten en Zwier van der Vegte, bedrijfsleider op praktijkcentrum De Marke, zijn nog niet erg enthousiast. Op extensieve bedrijven en in het teeltplan als tussengewas hebben ze zeker toekomst, maar ze zijn nog steeds geen serieus derde gewas na maïs en gras.
