How Fundamental is the Fundamental Assumption?

I argue that the assumption is flawed in this general version, but should be restricted, not to apply to arguments in general, but only to proofs. I also argue that Dummett’s and Prawitz’ project of providing a logical basis for metaphysics only relies on the restricted assumption.
Developing a design approach, exploring resistance and ambiguity

Designers face the world’s complexity at an experiential level. We consider Making (synthesising and concretising) an essential activity of designers, prior to Thinking (analysing and abstracting), because only through experience – a result of acting in the world – we achieve meaning, funnelling human intentionality. Making enables designers to explore the unknown by trusting their senses and their kansei, exploring resistance and ambiguity and by tapping into their intuition (Sennett, 2008). Because “intuition begins with the sense that what is not yet could be” (Sennett, 2008, p. 201), it involves skills, as skills are our way to make sense of the world, transform it and to cater for ethics.
In this paper we describe a one-day workshop that has been held during the CHItaly conference 2011 in Alghero, Italy. During that day, we explored how the integration of points of view, using intuition through skills can communicate and create a richer meaning. The assignment was to design an empowering/enabling tool that allows a person to begin to experience another person’s skill. To be able to design such a tool, designers had to go through several steps of documenting and reflecting upon their own and each other's skills.
We reflect on the experience and explain how this approach can support the integration of points of view, which is considered to be formed by personal experience, by skills, and by kansei.
Do We Need Real-Time Hermeneutics? Structures of Meaning in Games
Think Design Play: The fifth international conference of the Digital Research Association (DIGRA). Hilversum, the Netherlands: DiGRA/Utrecht School of the Arts, September, 2011.

These qualities change how games create and transmit meaning to their players. The concept of “real-time hermeneutics” (Aarseth 2003) is analysed in order to understand how temporality affects the understanding of games. Temporal frames (Zagal and Mateas 2010) are introduced as an alternative way of understanding time in games.

After outlining the motivations for 2D semantics as a response to externalist thought experiments, I argue that the approach faces an internal tension in fully vindicating the traditional role of meaning. I contrast the 2D theory's broadly descriptivist approach to meaning individuation with a relational approach.

The Contextual Game Experience: On the Socio-Cultural Contexts for Meaning in Digital Play

Therefore the earlier SCI model of gameplay experiences is not sufficient to cover the full range of game experiences. In this paper a more comprehensive model is presented by describing the multiple contextual layers that surround and underlie every encounter with digital play and games.

Lady in the Radiator: Phenomenology, Embodiment, and the World of Eraserhead.
This is an essay I wrote about 11 years ago.
I originally delivered it at the fourth annual conference of The Society for Phenomenology and Media (SPM) in Puebla, Mexico.
A streamlined version of it is published in the 2002 volume of Glimpse, a publication of SPM.
Despite few minor misgivings here and there, one or two things I would have done differently (both in regards to style and content), this piece still captures an essential vision of mine. It contains a number of themes which I plan on developing in the future, albeit generalized far beyond Eraserhead. I look forward to any feedback!
It is interesting to note, finally, that some four and half years after I wrote this essay, David Lynch would pronounce Eraserhead as his "most religious film" (in his 2006 book, Catching the Big Fish).

Harmony, Normality and Stability
by Nils Kürbis
As the title says: my account of proof-theoretic harmony, normality and stability!

This paper specifies such a function. I specify two kinds of rules, one in which it is more natural to assume an introduction rule to be given and elimination rules are determined from it, and another kind in which it is an elimination rule which is given and the introduction rules are determined from it. The process also works the other way round, so that it doesn't really matter which rules are supposed to be given first. The process is very general and applies to a large class of logics. The paper begins with a discussion of the philosophical importance of this in connection with the notion of harmony. I discuss Dummett's ideas on harmony and stability, which is supposed to be stronger than harmony. Dummett suggests that normalisability is a formal criterion of harmony. However, he seems to aim at something else, and this criterion does not give an independent formally precise notion of stability. I propose formally precise definitions of harmony and stability, which are distinct from normalisability. My aim is not exegetical, and according to my definitions, classical as well as intuitionist logics count as governed by stable (and hence harmonious) rules of inference.
