Dear Klaus I agree that we "cannot ascertain consensus on what two or more people actually see, feel, or experience." When we get to this point of agreement we have already established something more interesting and useful to design: we have established a theory of mind. While I can not know what you see, I not only can imagine it is something like what I see (which it frequently is) but I can also establish, by questioning what I see, how it might be that you come to a different conclusion about what is there. This is the everyday day event when we say "I see what you are talking about". For a designer this allows that they can inhabit various possible minds based on their experience of other minds and they can survey other minds to determine just how something might be seen. This ability can be developed - it is part of de-centering that has been mentioned from time to time. my car is white keith russell OZ Newcastle >>> Klaus Krippendorff <[log in to unmask]> 05/25/05 3:57 AM >>> interesting comment i like to make a distinction between con-sensus and consensus. why do we have such a quick consensus (agreement that is asserted in language) that the car we con-sense (see jointly and at the same time) is black? because we have learned to use the word "black" in the presence of things that other people label "black." color blinds can learn to say the word "green" or "red" when they see a traffic sign, not because they see green or red, but because designers use sensory redundancy, enabling the red/green colorblind to identify colors by the position of the light. you can observe con-sensus -- whether we face the same thing you can ascertain consensus by verbally agreeing that something should be called so and so but you cannot ascertain consensus on what two or more people actually see, feel, or experience. klaus -----Original Message----- From: PhD-Design - This list is for discussion of PhD studies and related research in Design [mailto:[log in to unmask]]On Behalf Of Filippo A. Salustri Sent: Tuesday, May 24, 2005 8:11 AM To: [log in to unmask] Subject: Re: theory as a car: theory and theorist and their contexts Klaus, Right. I agree, almost completely. Indeed, I said as much (tho possibly not as well), when I prattled on about being cut off from reality by my perceptions. Indeed, the "spectrum of light" you refer to may itself be regarded only as an artifact of our perceptions. Still, with relatively little effort, most humans can quickly reach consensus about 'black' versus 'blue'. The act of reaching that consensus is extremely interesting to some people. More power to them - we need people to think about such things. I just prefer to work on other things. Like: assuming such consensus is possible (and it is, unless I'm imagining the whole universe), then how can we facilitate gaining one kind (not the only kind) of understanding of (our models of) reality through entirely conscious (rational) methods? One way to account for inconsistencies in the consensus we build is through the use of 'context'. Another way is through logic. It ain't a silver bullet - but it can afford a certain perspective that is unique compared to other methods. Cheers.
