Introduction :

The questions that animate this Open Lab are meeting some of my preoccupations. That’s the explanation of my presence among you.

Let me introduce myself : I’m the managing director of a social work company. It’s a non-profit organisation that accompany persons with social difficulties : Children, parents, excluded minorities, persons with disabilities, frail elderly, political refugees, pupils, young workers, among others. I’m responsible for around a thousand and two hundred employees divided in thirty-four establishments within the department of Finistère. Apart from that, PhD in sciences of the information and communication, I lead theoretical research on social work, management and work organisations.

Let me tell you how your questions are meeting my interests :

  • What’s the difference between the public and the private space ? This question is at the core of institution’s lives. What makes the institution is the way human beings organise a « common law » among themselves, by marking out the spaces, the level of responsabilities, the different places of activities… Particularly with social work, the limit is sometimes thin between what is professionnal posture and personnal involvement, even militant engagement. I postulate that it’s this articulation between public and private, never really fixed, that is structuring the organisations (therefore is also the city).
  • Where is the unkwnon in a city ? This question is not only concerning the city but any kind of human organisation. We are experiencing a time of rationalisation of every life form. It’s a sort of scientism that is feeding a myth that says that living things can be perfectly understood, enclosed, identified, mastered and controlled. Yet, in any form of organisation, there is grey areas, unknown elements. I postulate that these « unknowns » are major organisationnal stakeholders.
  • How is the city transforming itself throughout our perception shifts ? This question represent the core of my researches – Founded on a constructivist approach[1]. The way of perceiving an organisation (a company or a city) is determined by preconcieved representations, ideologies, thinking patterns. This perspective is « conforming » the organisation. Shifting the way you look, modifying your point of view is changing the way the organisation is « conformed ». That’s what I’ll try to show you with the concept of threshold organisation I’m opposing to the self-centered work organisations.
  • Where is the space for social and sensorial meeting within the city ? Contrary to popular thinking, the space for meeting is not the center of the organisation. Everything happens in the thresholds, that are the sceneries of welcoming. These thresholds are not necessarily at the periphery because the meeting places are a network of apparatus that draw the relational space. We’ll get back to this.


Now that you perhaps understood a bit more why I was interested in participating in your exchanges, I will try to develop some of the points brought up by your questions.

  1. A sensorial approach to organisations

Approaching an organisation « sensorially », it’s considering it through it’s peripheries, it’s thresholds. Indeed, the body senses are not located at the center of the organism, but at it’s periphery. The eye allows the immersion into the physical space, the ear permit to orientate, but also to communicate, the smell is mainly a way to identify and label the context, the skin is an immense zone of contact and perception/welcoming, and, finally, the taste brings us the flavour of the environment in which we evolve. None of these senses is withdrawn onto the organism, they are all open to the outside.

  • Sense = Frontier

The sensorial approach of organisations brings us naturally to focus on it’s frontiers. This zone, delimitating the borders of the organisation is not hermetic. The limits, necessary to the identification of the organisation (the geographical limit of a city, the enclosure of an establishment), are not partitions but porosities. The frontier is, by definition, a place of passage, of exchange. Thinking the organisation on the base of permeable frontiers draws our attention to the flow, the streams, the energies coming in and out, traversing the organisation. The sensorial approach is preserving us from the common thinking consisting of limitating the perspective on looking merely at stocks (the number of inhabitants of a city, the turnover of a company).

  • Sense = interface

Getting interested in the sensorial dimension of organisations is disrupting the notions of « inside » and « outside ». Indeed, if the ear is perceiving external sounds, it integrates it immediately in the inside and assimilates it to process it. Can we say that the sounds are « outside » or « inside » ? This question, within a sensorial approach of phenomenons makes no sense. The senses has an interface function meaning they allow the integration of what is outside the organisation and externalising what is internal in the organisation. This conception deconstruct the xenophobic myth of an organisation totally foreign to it’s context.

  • Sense = immersion

Contrary to what rationalists approaches can make you think of, an organisation is not limited to the surface it’s assigned (the entry sign of a city, the surrounding walls of the establishment…), it’s an element of a system in which it interacts. The sensorial perspective is totally ensuing this environmental immersion of any organisation. The organisation sees, feels, touches, hears, tastes, the environment in which she evolves and to which she is totally dependant, to which it’s survival is relying on. Any human organisation is part of an « eco-socio-system ». Being fully aware of this allows one to consider a real ecological relationship of the organisations among themselves and with their environment. The sensorial perspective restrain the predatory relationship the organisations can develop with their environment when, instead of being aknowledged as the breeding-ground fertilizing them, it is experienced as a danger (the competitive environment of companies or the rural/urban relation of big cities) or worse, like a resource to be consumed.

  1. Sense, threshold and organisations

A sensorial approach of human organisations leads us to consider their thresholds rather than their centrality. It’s a shift of viewpoint. I postulate that changing your point of view is basically transforming the organisation itself because different elements are valued, different phenomenas are unveiled. Focusing our attention to the « weak signals[2] », we show another face of the organisation, probably closer to what’s really structuring it. This change of sight modifies the organisation.


In order not to be too long, I will only develop two essential aspects of what is the concept of threshold organisation : polycentrism and polyarchy.

  • Centrism, acentrism, polycentrism

The concept of threshold organisation can be conceived as an act of resistance to the self-centered conception of structures. The common thought is a centralist, centralistic one. It’ the center that counts (the city center as an exclusive and excluding identity of the city, the management direction of the company as the only operating reality).It acts then as a « black hole », meaning an energy absorber of the system.

For example, that’s what happens when a company regroups at it’s head office the accounting departement, stripping off the peripherical offices of it’s competencies. Historically, that is how the relationships between the city centers and the peripherical areas, the suburbs was built. Centers are provided with the services and fitted out with care. Suburb are under provided with services for the public and with an approximative urbanism.

This centralistic manner of thinking out the organisation has counterproductive effects : when a stable organisation must profit from an equally divided instutionnal density at all it’s points, the self-centered organisation has a consequent density in it’s center and a very weak one in it’s surroundings. The edges of the organisation are then seen as fragiles – when they are on the contrary the strong points of it’s capacity of exchange with the environment – and therefore, the intent is to consolidate them by raising walls to protect them from a threatening environment. The external/internal connection is then built following a protectionnist logic of closure.

In truth, an organisation, in reference to the complex thinking of Edgar Morin[3] is all in all marked by it’s centrism, it’s acentrism and it’s polycentrism. These three concepts are not disagreeing with one another, they are complementary and interacting :

  • The centrism of the organisation can be, for instance, it’s directing body that requires a certain centralisation (the mayor, the city council, the director, the executive hierarchy) ;
  • Acentrism is the idea that the center cannot be really occupied, that there’s always a certain vacuity of the central space, a void that is the condition for the system to live (the center cannot control everything, the peripherical elements don’t always need the center) ;
  • Polycentrism sheds light on the structuring knots of the organisation, forming precise but informal networks, strong but fluid and flexible (these are the places of counterpower, marginal spaces, subvertion of some members…).
    • Hierarchy, Anarchy, Polyarchy

The self-center thinking focuses it’s analysis on the hierarchical system of the organisation symbolically represented by a pyramid. A pyramid is not an unstable system, when it’s the necessary condition for life. The only known stability of living systems is metastability that associates catabolism and anabolism[4]. In short, hierarchy cannot be seen as a stable system, established once and for all. The threshold organisation is interested in the unstable elements of the system, the energies that destabilizes it. If a hierarchy is necessary to the steering of the organisation, it must be seen in all it’s systemic components. It’s counterweighted by anarchy, meaning a state of disorder in which the organisation is finding itself due to the weakness of the central power. For hierarchical power is never almighty – even dictatorships proove their weaknesses – because it constantly has to deal with other threatening forces. Anarchy is contestation of the power, it’s the dissipative structures that challenge what’s neatly organised. Anarchy participates to the construction of the organisation by repeatedly reconsidering what seems acquired.

For example, in a company, the ratio of power introduced between the direction and the syndicates of employees – relationship often anarchical because nobody is really grasping it’s very nature – are much structuring for the organisation. For example, in a city, the illegal installations (Slums, refugee camps, Romani camps…) are participating into the urban topography.


In fact, every human organisation is polyarchical. In other words, made of the intertwining of multiple structuring lines each adding to the construction of the system. Hierarchy – confronted to anarchy and controlled by it – crosses the functional lines – the complex articulation of competencies and expertise of the stakeholders – but also key lines of a whole other kind: affinities, solidarities, and individualisms, cordialities and acrimonies, groupement of interests, etc… Each of these lines contribute to the ratio of power that shapes the organisation.

To illustrate this with an urbain terminology, one just has to look at the architectural way the city is structured, with it’s streets and avenues, it’s penetrating arterial roads, is peripherical ways, but also the way it’s transformed when a metro is added, like in Rennes, a tramway, like in Nantes and the face it wears when the pedestrian areas are restructuring the city center. All these ribs can be seen as figures of urban polyarchy. Whether you bike, walk, drive or use public transportation, the lines that order the city are not seen the same way, but all of them make the « city » for all. To draw a metaphor with a company, whether you are the managing director, union delegate, employee or service user, the ways of the organisation aren’t the same.


  1. Seeing the city through it’s thresholds

To finish with, I’d like to come closer to the theme of the Open Lab and lay my interest on the city. I suggest you to try seeing what could be the concept of threshold organisation applied to the city

  • The open

Seeing the city as a threshold organisation – and not a self-centered organisation – it’s go look for what is, in it’s form and way of being, is openness, interface, interaction with it’s environment.

The thresholds of the city are the sceneries of welcoming, the places of alterity. Alterity is the dual dimension of the identical – the ego – and the difference – the alter – it’s the experience, with the other, of our common humanity and the radicality of our individuality. These thresholds, spaces for the meetings, are not solely located at the edge of the city but also inside of it. In order to understand what the thresholds of the city are, it’s important to identify all the places where the welcomings, the alterities and meetings are played – in a theatrical sense, with scenarii, stagings, intrigues and temporalities.

The sceneries of the welcoming are marked by a double movement : welcoming / be welcomed. It’s a composition manifesting an event, seen and known by all, an action composed by stakeholders, games that are more or less determined when appearing on stage, putting on stage and putting oneself on stage. The sceneries of welcoming are the spectacle of the openness of the city : openness to the other, openness to the environment, openness to oneself. The sceneries of welcoming are this vacant spaces left to face the other, allowing him to come, to welcome the city that is welcoming him, to be welcomed by it and it’s inhabitants.

What’s at stake, here, is alterity. The other, it’s the stranger, the one that does not live in the city. Stranger he might be, nonetheless, he is here and now, already here, present and yet signifying the otherworldliness. The open of the city, it’s all in the same time it’s capacity to welcome the strangeness and the stranger, it’s capacity to integrate it meanwhile acknowledging it’s difference.

At the term of this process, the open of the city creates interaction. What makes the city, it’s these spaces of meeting, these relational spaces that show the sceneries of the welcoming where the alterity is displayed. The entrance of the city, the streets, the squares, the terraces of the cafés, the train station halls, the bus and metro stations, the forbidden lawns, the parking lots, etc. In short, the public space, or more precisely everything that is not private space. But it’s not the public space as we commonly think of it : it’s the plural spaces (polycentrists and polyarchicals) where being welcomed and welcoming is happening.

  • The in-between and the interstice

At this stage of our description of the « threshold » city, we can distinguish the fact that what structures the city is not it’s fillings but it’s voids. In other words the spaces left vacant to allow the meeting, the interaction. It’s a hackneyed urbanistic thought, that what makes a city is not it’s buildings and blocks, but the streets and the interstices between the buildings. What makes the city is what allows one to circulate and move in it. The street is the condition of it’s architecture. Without interstices, the meeting of the other is no more conceivable.

It is therefore the open spaces in the city that needs to be identified as the structuring sites of the city, in other words, where the « living together » builds-up, a concept cherished by the greek city-state. It invites us no to conceive the city by it’s densities, it’s solid and massive aspects, but by it’s frailties, it’s flows, it’s « holes », it’s lackings : that’s when the decisive elements making the society, building the « common » are at stake.


We started from the questions asked by the presentation of the work project of the Open Lab. The most watchful listeners might have noticed I left aside two questions from the initiating text of your working days : « How, and do we have to poetize the city ? What is a poetic meeting ? ». But in my opinion the theory of organisation I’ve been sketching with you is not free from a certain poetic dimension. To underline it, I propose to quote these verses from a Breton poet and friend of mine Jean Lavoué :

Les villes se mirent aux façades

The cities look at themselves through the facade

De soleils factices.

Of artificial suns.

Elles encagent l’intime

They cage down the intimate

En des palais qui ne célèbrent qu’eux.

Within palaces that celebrate nothing but themselves.

Dès que tu le peux,

As soon as you can,

Quitte l’ornière quadrillée,

Leave the chequered rut,

Ce jeu de glaces,

This trick mirroring game,

Ce piège aux alouettes !

This trap for smoke and skylarks ![5]


Our departure point were the questions ask in the press file of the Open Lab : « What is the difference between the public and the private space ? Where is the unkwnon in a city ? How is the city transforming throughout our perception shifts ? Where is the space for a sensorial and poetical meeting in a city ? »

The initiatory path we took first showed the proximity there can be between a reflexion on work organisations and the city : They are both human organisations that are systems based on common principles, because it’s places that make « society ».

Then through the twist and turns of the complex thinking, we identified the singular way an organisation is disclosed when we focus more on it’s thresholds than it’s center, on it’s flows rather than it’s « stocks », on it’s interdisciplinarities rather than it’s structures. Polycentristic and polyarchical, the viewpoint built with the concept of threshold organisation allows us to enrich the way we look at cities. We’ll look for what is thresholds, sceneries of the welcoming, places of alterity, spaces for the meeting. For it is indeed by it’s vacuities, it’s voids and misses that the city acquire it’s meaning.

As a conclusion, let’s hear another poem from Jean Lavoué :

Ouvre grand !

Open wide !

Laisse venir la vie

Let life come right in

Qu’elle s’empare de tout

Let it seize everything

Que rien ne lui soit étranger

Let nothing left foreign to it

Que rien ne soit fermé à sa lumière

Let nothing be shut from it’s light

Que tout soit imbibé par son chant !

Let everything be soaked with it’s chant !

Ouvre grand !

Open wide !

Dégage l’horizon

Free the horizon

Etends tes branches vers le soleil

Spread your branches to the sun

Laisse aller vers la source la barque de ton être

Let the barque of your own self go to the source

Laisse-toi seulement guider vers l’autre face de toi-même

Only et your self be guided to the other face of yourself[6]
