323. Script and narrative

In this blog (item 31) I presented my theory of invention, in the form of a ‘cycle of discovery’.  To clarify it I used the notion of script (item 35). A script is a structure of connections between nodes that represents and guides action. The nodes represent constituent actions, linked into a coherent whole of a practice. The links represent a sequence, logical implication or causal action, or transfer or sharing of resources. The classical example is that of a restaurant, with nodes of entering, seating, selection, ordering, eating, paying and leaving.

The notion of a script is useful to illustrate the difference between different forms of innovation: change of nodes, the sequence of nodes, the connections between them. Thus the innovation of self-service restaurant entailed a change of sequence: selection, ordering and paying precede seating and eating.  

It also illustrates how there can be levels of innovation, embedded in each other: nodes have their own subscripts: different forms of paying in the payment node, for example. They also have superscripts: how the restaurant is embedded in its environment, in its location, access and parking, in arrival and departure of clients and supplies..

Here I want to elaborate on the notion of scripts, again using an insight from Jerome Bruner, as I did in the preceding item.[i]

Ever since I started using the notion of a script, I have been reflecting on what the ontological status of it is. Is it something given objectively, documented in some written operating procedure, as used for training personnel, perhaps, or as the printed script of a theatrical play? Or is it a mental representation of the process, built by participants in it, perhaps not even deliberate but subconsciously, forming part of ‘tacit knowledge’? In that case, how rigorous or even definite is it? And how idiosyncratic?

Bruner contrasted the script with what he called a ‘narrative’. That has the following features:
1.      It is ‘diachronic’: developing and varying in time
2.      It is particular, not universal but context- and individual-specific
3.      It refers to ‘intentional states’ (belief, desire, fear, ….) and how they are affected by events. It is not a logical or causal explanation. It indicates reasons, not causes.
4.      It is hermeneutic: subject to a variety of interpretation. It does not carry a single ‘true’ or ‘correct’ meaning but yields an intuitively appealing account.
5.      It is not only the case that he meaning of the whole depends on that of the parts, but also the other way around: the meaning of the parts depends on that of the whole, depending on the context. Bruner notes that this narrative comprehension is one of the earliest moves of mind to appear in the young child.

Concerning the last point Bruner also refers to the ‘hermeneutic circle’, which I discussed (in item 36 of this blog) and used as an example of the emergence, in the emergence and shift of meaning, in the preceding item on emergence.

And now the point is this. Narratives require scripts as necessary background, but those do not constitute the narrative itself. Scripts are often implicit, and may be breached ‘from a precipitative event’, which leads one to see things in a different light. Narratives vary with context and individual while ‘maintaining complicity with the canon’.

Two things, now. First, this is strongly reminiscent of the distinction de Saussure made between ‘langue’, which is the canon, and deviations and variations from it, in ‘parole’, which I mentioned in the preceding item in this blog.

Going back to invention, there is a canon of established ‘normal practice’, in a script, which may or may not be written down, as the ‘langue’ of the practice, but it allows for idiosyncratic and contextual variation, the ‘parole’ of invention, and that is what drives invention from application in novel contexts, as argued in my ‘cycle of discovery’.
