De ‘#HekkenKruisFilosofie’ die mee aan de basis ligt van het Blauwhaus experiment en in kasteel Blauwendael spelenderwijs verder werd ontwikkeld, bestaat uit een eigen terminologie van sleutelconcepten of tags die vaak meerdere betekenissen uitdragen. De ‘filosofie’ biedt een kader om de belangrijkste uitgangspunten die in het project werden geïntegreerd te benoemen en duidt meteen op de al dan niet wetenschappelijke queeste naar kennis en wijsheid die intrinsiek deel uitmaakt van doctoraatsonderzoek. De verschillende concepten zijn in zekere zin fluide omdat ze voortvloeien uit een gradueel bewustwordingsproces waar vaak een ideologische attitude mee gepaard gaat. Er kunnen dus steeds nieuwe sleutels aan het vocabulaire toegevoegd worden terwijl andere principes of labels geleidelijk kunnen uitdoven.   

De naam verwijst naar het hekjessymbool ‘#’ dat vaak ten onrechte het hashtag symbool wordt genoemd. Een ‘hashtag’ omvat het hekje als voorvoegsel maar wordt meteen gevolgd door een tekencombinatie, één woord of meerdere woorden zonder spaties ertussen. Op digitale sociale netwerken zorgen hashtags ervoor dat bepaalde berichten gemakkelijker gevonden kunnen worden, een voordeel waar we dankbaar gebruik van maken want ook de #HekkenKruisFilosofie kan als hashtag toegepast worden.

Hermes leert ons dat de hashtag in het Frans officieel mot-dièse (woord-kruis) heet. De interpretatie van het hekjessymbool als (muzikaal) kruis en het kruiswoord(-raadsel) dat door deze samenstelling wordt opgeroepen, heeft mee aanleiding gegeven tot de benaming ‘HekkenKruis’ wat meteen mooi te rijmen valt met ‘gekkenhuis’. 

Tenslotte verwijst de naam ook naar de functie van het hek als fysieke begrenzing, dat geopend en afgesloten kan worden om projectconcepten te kaderen, af te bakenen of net open te trekken. De afzonderlijke componenten van de ‘filosofie’, de ‘sleutels’ of concept tags omvatten meestal verschillende connotaties en dus kunnen ze op uiteenlopende manieren geïnterpreteerd worden. Ze werden dus gedefinieerd met een zekere dichterlijke vrijheid. Om de werking van de #HekkenKruisFilosofie te begrijpen, is het belangrijk om mee te geven dat de verschillende componenten vaak op elkaar inwerken en  soms deels overlappen.


The '#FenceCrossPhilosophy', which lies at the heart of the Blauwhaus experiment and was developed in a playful manner at the castle Blauwendael, consists of its very own vocabulary of key concepts or tags which often allow for multiple interpretations. The 'philosophy' provides a framework for identifying the main principles that were integrated within the project and instantly points to the more or less scientific quest of knowledge and wisdom that is an intrinsic part of doctoral research. The different concepts are in a way fluid because they arise from a gradual process of awareness often encompassing an ideological attitude. Thus, new ‘keys’ can be added to the vocabulary at any time, while other principles or labels can gradually fade out.  

The name is derived from the Dutch name for the number sign “#’, the 'Hekjessymbool' ('hekjes' can be translated as ‘small fences’) that is often wrongly called the hashtag symbol. A 'hashtag' includes the same sign as a prefix but is immediately followed by a character combination, a word or a phrase without spaces. On social networks, hashtags make it easier to find specific content and messages, an advantage that we gratefully apply because the #FenceCross- Philosophy may also function as a hashtag. 

 Hermes reveals to us that the hashtag is officially called mot-dièse (word-cross) in French. The interpretation of the number sign as a (musical) cross and the crossword (riddle) evoked by this compound, has also prompted the name 'HekkenKruis' ('FenceCross'), which immediately rhymes beautifully with 'gekkenhuis' ('madhouse').

Finally, the name also refers to the function of the fence as a physical boundary, which can be opened and closed in order to frame, demarcate or actually to open up project concepts. The separate components of the 'philosophy', the 'keys' or 'concept tags' usually encompass multiple connotations and allow divergent interpretations. They were thus defined with a sense of poetic freedom. To fully grasp the functionality of the ‘philosophy’, it is important to point out that the separate components all intermingle and sometimes even overlap.


A concept tag which points towards an attitude characterized by seeking alternative strategies to tell a story, deliver a message or share information, with the purpose to create a puzzle which is supposed to stimulate (autonomous) reflection by establishing an atmosphere of deliberate ambiguity through (mis)use of language, signs or logical structures. It usually contains an element of play and riddle, and entails an intentional disorder which strives for a seductive and idiosyncratic maze to be explored. 


This concept tag was conceived as a reflection on human nature, stupidity and our individual and collective responsibility towards Spaceship Earth. It is rooted in the Anthropocene and combines the attitude of genuine craftsmanship (as characterized by self-reliance, social involvement and a constant striving for quality) with elements of anthropology and science fiction. It is tied to notions of (societal) resistance.



This tag highlights the interaction between our senses (or sensations) and the functionality of memory. It cherishes the spectrum of emotions between sweetness and sadness or disappointment, between nostalgia and melancholia. It is related to the concept tag #MixedEmotions.


The Blauwhaus is a concept which gives expression to a utopian longing for a better way of living and improved working conditions, characterized by collaboration and participation. It is driven by dynamic imaginative forces and may be attached to a wide variety of (inter)actions intended to inspire, spread a message of hope and/or improve happiness. It may also include an educational component.


A tag invented to describe a (new) methodology for resourceful (artistic) research which involves urban exploration, immersive social interaction and requires an unbiased attitude towards local communities, attitudes and customs. It  requires collaboration between experts and skilled practitioners with different backgrounds, interests and from different fields.

It may also involve an attempt to bridge the present and the future by digging up ancient legends, tales or (local) histories. It follows an immersive strategy of critical inquiry and social infiltration. It is closely related to the concept keys #FieldWork and #QuestioningEverything



A more or less euphemistic tag which relates to collaboration and can be applied when a specific situation requires a deliberate exaggeration in order to motivate team members and/or grasp the reader or the public’s attention. The Dream Team name, like the A-team, suggests that the team members are of the finest quality, unparalleled; or that its members were brought together to pursue a dream - perhaps even a fata morgana - and are called upon to collaborate on making this dream come true. Of course the tag can suggest both. While it reminds us to be gentle and kind to those who are willing to participate and help, it also reflects the potential of anachronistic, perhaps even courtly rhetorical language as a social motivator.








One of the most striking tags when it involves trying to describe what the Blauwhaus project is all about: building bridges and merging different worlds.  From personal drama to moral messages, from overt confession to analytical description. From education to abstraction.

#Making Waves



Refers to both a physical and a psychological distance that can be bridged without excessive effort and points to a strategic exploration or process-conscious approach to 'something close by', which still seems a bit strange or remains distant. The label refers to the notion of ‘proximity’ in all its facets, also on an (inter)personal level. It can indicate an exercise to pay attention to the commonplace, to explore its potential and/or to seek pleasure, inspiration and contentment in the simple things or in matters that are often obvious.
