From Enabling Prejudices to Sedimented Principles

by

In my post From Sedimented Principles to Enabling Prejudices(March 2013)  I distinguished the category of design heuristics from other kinds of principle. Following Peter Rowe, I call these Enabling Prejudices.

Rowe also uses the concept of Sedimented Principles, which he attributes to the French philosopher Maurice Merleau-Ponty, one of the key figures of phenomenology. As far as I can make out, Merleau-Ponty never used the exact term “sedimented principles”, but he does talk a great deal about “sedimentation”.

In phenomenology, the word “sedimentation” generally refers to cultural habitations that settle out of awareness into prereflective practices. Something like the “unconscious”. (Professor James Morley, personal communication)

“On the basis of past experience, I have learned that doorknobs are to be turned. This ‘knowledge’ has sedimentated into my habitual body. While learning to play the piano, or to dance, I am intensely focused on what I am doing, and subsequently, this ability to play or to dance sedimentates into an habitual disposition.” (Stanford Encyclopedia of Philosophy: Merleau-Ponty)

This relates to some notions of tacit knowledge, which is attributed to Michael Polyani. There are two models that are used in the knowledge management world that talk about tacit/explicit knowledge, and present two slightly different notions of internalization. 

Some critics (notably Wilson) regard the SECI model as flawed, because Nonaka has confused Polyani’s notion of tacit knowledge with the much weaker concept of implicit knowledge. There are some deep notions of “unconscious” here, which may produce conceptual traps for the unwary.

Conceptual quibbles aside, there are several important points here. Firstly, enabling prejudices may start as consciously learned patterns, but can gradually become internalized, and perhaps not just implicit and habitual but tacit and unconscious. (The key difference here is how easily the practitioner can explain and articulate the reasoning behind some design decision.)

Secondly, to extent that these learned patterns are regarded as “best practices”, it may be necessary to bring them back into full consciousness (whatever that means) so they can be replaced by “next practices”.

From Sedimented Principles to Enabling Prejudices

by

I have often asserted (on this blog and elsewhere) that principles are over-rated as a driver for intelligent action. However, that doesn’t mean principles are completely worthless. In this post, I wish to explore some of the ways in which principles may have some limited use within enterprise architecture.

I am going to identify four rough categories of principle. There may be other categories, and the categories may overlap.

1. Universal Truths
2. Governance
3. Style Preferences
4. Enabling Prejudices

This is a long post, and I think the final category is the most interesting one, so if you are short of time, please read that one first.

Following on from the previous post ‘Rules, principles and the Inverse-Einstein Test‘, there’s an important corollary about real-time sensemaking and and decision-making – it was in my notes for the post, but I forgot to include it, so I’ll do…
