The concern is spatial: a multiplication of the sites of engagement. The
story told is one of greater admission to the scenes of knowledge
exchange and production. The technologically-impelled history meets social
condidtions (and the historiographic crux of which determines which).

How did "tacit knowldege" sneek in here? Is it by way of a proposed
synonymity with "nonverbal thought"? Nonverbal thought can be expressed
and indeed that is the point made by the invocation of the development of
imaging arts. Tacit knowledge is in a sense held in reserve. It can be
converted to explicit knowledge: it is available to expression (at a
The bend, the hinge, the articulate turn, perhaps explains the ambivalence

Alongside the improvements in image reproduction there was an improvement
in the postal system. Hence the images did not stand alone, they could be
referenced and discussed. Hence the key and single word of the last
The images printed on a rectangular surface allowed for a grid to be
imaginatively imposed upon illustrations and diagrams. One can imagine the
exchange of letters that indicate upper left quadrant ... Likewise the
means for knowledge exchange and production rely less on distinctions
between verbal and non-verbal (or auditory and visual in some discussions)
but on the development of a shared means of orienting attention. The
shared means is sometimes a feature of tacit knowledge among experts (one
can think of acronyms and short forms in biblio references that are never
expanded in an artefact at hand; one can think of all the technical
symbols that dot a survey map or a blueprint). The tacity of shared means
fails when novices engage with complex artefacts or even simple artefacts.
One could be clever and suggest that thinking out of the box depends upon
what you put into it. However it might be a tad more accurate to stipulate
a mindfulness of who and when.
An image in the hands of illiterate persons -- illiterate in the sense of
not being able to "parse" the image -- is no more capable of circulating
in the social imaginary than an image without story along the songlines.
