The fourth major pillar of IDEAN‘s open ethos is a culture of conviviality. In most present day urban settings the category of neighbourhood is not congruent with the dimension of community. Sectors comprise heterogeneous populations and life styles, and conviviality addresses this fact. It also allows for anonymity, but requires civic courage. Mainly, it builds on the inclination of humans to socialise, communicate, question, care, to express solidarity – even towards ‚strangers‘. IDEAN‘s conviviality uses genuine places to promote communication, the experience of individuality and difference, the exchange of ideas, the production of innovation, and the co-creation of common goods and shared values. Thus, more than representing a particular culture, conviviality encourages synergies between different cultures.
