Reading Schutz’s observations of the “intentional gaze” I am realizing how important the concept of intentional mediation as a means to extend our intentionality (both active and receptive intention) is to my own thinking. This is the sentence that sparked it:

However, as I am always interpreting these perceptions as “body of another,” I am always interpreting them as something having an implicit reference to “consciousness of another.” Thus the bodily movements are perceived not only as physical events but also as a sign that the other person is having certain lived experiences which he is expressing through those movements. My intentional gaze is directed right through my perceptions of his bodily movements to his lived experiences lying behind them and signified by them signitive relation is essential to this mode of apprehending another’s lived experiences.

This concept of intentional gaze passing directly through a mediating phenomenon to an underlying reality (in a transparent and spontaneous act of interpretation) brings to mind a couple of seminal phenomenological example. The first is Merleau-Ponty’s blind man perceiving his path through his cane. The perception of the path passes transparently through the cane. The second is Heidegger’s concept of “ready-to-hand” where the intention passes from the body through the tool, and the tool becomes a transparent extension of the will.

Of course, as any praxis-aware designer knows, in tool use we are not simply acting on a passive object but interacting with some matter through the tool, in a complex feedback rhythm of acting and perceiving: crafting. (Crafting is the material form of instauration, the act of making-discovering. Crafting is discovering the possibilities of a material while also shaping the material in response to what is sensed as possible.) Most of our crafting is mediated through tools, through which we act upon an object and also through which we sometimes perceive the object and its possibilities.

So, between Heidegger’s will-extending hammer and Merleau-Ponty’s perception-extending blind man’s cane is a range of intention-extending instruments that mediate both action and perception.

And among these instruments is the most important instrument of all, concepts. Through concepts we perceive and respond to phenomena and, by extension, reality. (Thinking about concepts as transparent, mediating, intention-extending tools for forming perceptions, conceptions and consequent judgments, beliefs and actions — tools we can and should try out, compare and evaluate before adopting them is the subject of my next book, tentatively titled Second Natural.)

Obviously, seeing craft this way — and more generally, instauration — blurs the traditional boundaries between self and non-self, even beyond the blur generated by extended cognition, which is why I’ve called this “extended being”. But maybe calling it extended existence would be better.

A couple of years ago, when I was reading postphenomenology, recalling the deep connections between phenomenology and existentialism, I wondered what the existential analogue of postphenomenology would look like. What could postexistentialism look like? If I weren’t all posted out, I might be tempted to call my design instrumentalism — this idea that we ought to treat our transparently intention-mediating concepts as designed artifacts that we can compare with alternatives, adopt, or modify or reject — as post existentialism. What could be a more radical form of self-determination and responsibility than to instaurate our concepts with intention?
