In the Earth’s atmosphere, the mesosphere is the layer between the stratosphere, where the airplanes travel, and the thermosphere, where the spaceships fly. It is thus the strata that is the least impacted by human activity, and one which we like to think of as carrying hope. Taking this layer of the Earth’s atmosphere as a metaphorical point of departure, the magazine Mezosfera—with a fictitious “pan-Eastern European spelling”—sets out to look at, connect, and engage initiatives that can be conceived as working in the middle ground, in the mezosfera layer of our contemporary art and cultural world, in-between grassroots and institutionalized practices.

It would be difficult to identify, within the post-1989 Eastern European landscape, another realm that has undergone an equally intense labor of dispossession and resistance, of redefinition and reconceptualization, than the realm of the “public:” the state and state assets, public life, public institutions, and the public space. There is hardly anything, at the same time, that challenged the public heritage of the socialist state more than the neoliberal understanding of the primacy of the “free,” “unconstrained,” private initiative.

My interest in “walking theory” initially came from an education in art and humanities, which taught us that art was an intimate activity of the artist-genius who creates directly from his guts, while theory was an abstract speculation, which, if you let it come closer, can castrate artistic freedom. Paradoxically, all this was promoted in Belgrade in the 1990s, in the context of the civil wars in the former Yugoslavia, the international sanctions, the regime of Slobodan Milošević, and the transition from socialism to capitalism.

It is difficult to imagine unlearning. One thing that stands in our way is our initial understanding of the word. Is it even possible to simply leave dominant knowledge behind? My immediate answer is “no,” for two reasons. First, there is no way back. There is no path that leads us to a time or place before the history of relations of power and violence that are responsible for what we know today. Secondly, unlearning is not an easy task. For these reasons, it is worthwhile to take a closer look at how it is discussed in postcolonial theory.

For East-Central European countries emerging out of the period of state socialism, it was only after 1989 that the civic sphere and civil society could make themselves felt as constructive elements of democracy. An agent of the development of the democratic order, civil society represents a significant force in opposition to political power, for instance in its capacity to thematize sensitive social questions, form public opinion, assert values, and keep the government in check.
