From diversity to plurality - Equality and difference in political adult education
The diagnosis is clear: Education is lagging behind demographic reality. Educational institutions, didactics, curricula, as well as teaching staff do not reflect the increasing diversity seen in our societies since the 1960s. In no way do I want to discount the good intent, achievements, and positive developments. But the discrepancy between the demographic structure and the daily routines in education is obvious.
This must be explained. Which categories of difference do we mean when we talk about diversity? For instance, the ‘prohibited grounds of discrimination’ in EU regulations such as age, ethnic background and nationality, gender, physical and mental disabilities, religion, belief, political or any other opinion, sexual identity and orientation, class, etc.

These are highly varied categories of difference that cannot be translated into one another or reduced to a common entity. The spectrum within these individual categories also often differs from region to region. The terms ‘ethnic background’ in Austria and the American (or British) ‘black’ do not designate one and the same difference. Nevertheless, the discussions surrounding diversity are sometimes very heated and fierce, as if only two parties were involved.
The Dutch writer Carry van Bruggen expressed a concept in the 1920s that has long guided my thinking: There is no being other than being different. 
If we, following the author, presuppose that the being that we perceive around us, i.e. the other, is always a separate, unique being despite its similarity with a group of further others, we would learn three things:
The other is not different viewed from my perspective, but by virtue of its very existence. The other is neither the antithesis nor the instigator of the own. It is simply the other, independent of me, just as all others are also the other. Thus, one can only be different.
Differences between individuals (people, things) are fundamentally infinite. But when we talk about politically relevant differences that are expressed in social groups, this involves an act of reduction.
This reduction is due in part (and in addition to historically evolved political and social struggles and conflicts) to a conceptual shortcoming that permeates our logic and our languages: We are incapable of expressing difference as difference in and of itself. Thinking in opposites results in difference always being expressed as identity when articulated in a positive form. Collective identities are based on reductive differences that cannot be conceptualised.
Difference is the one side of the coin. The other side pertains to equality. This also has its roots in ancient philosophy and is delineated by a related term: identity. Heidegger wrote:
‘When one constantly says the same thing, such as “the plant is a plant”, that is tautology. For something to be the identical, one is sufficient. Two are not required as they are for equality.’ 
Identity refers to two or more entities or objects conforming in every respect, i.e. an absolute lack of differences: A is A. Equality, on the other hand, refers to conformity in a relevant aspect, but not all aspects: A = B. As Heidegger stresses, this differs from identity in that one element would be sufficient for identity. For statements about equality, on the other hand, we require at least two elements.
So first, this means that equality is not an absolute term, but always describes a relationship. And before we can talk about equality between two entities or objects, there must be one or more relevant differences between them. Thus, equality is only possible as equality of the different.
This, in turn, would imply that diversity is the ‘normal state’ of a society. But when one says that our society has become diverse today, this is a ‘by-product’ of hegemonial policies – because they depict existing differences as coherence, the diverse as a unit, the heterogenous as homogenous. Counter-policies positioned/position difference against this homogeneity. To this end, the politics of difference pursues a dual strategy: (re-)heterogenisation of the homogenised and embracing that which was excluded (during homogenisation).
In the political context, diversity is brought into play to help a difference attain equal standing or recognition. And this is a challenge that education must also address. De facto diversity requires a political expression that can instigate actual equality (also in education).  The political expression of diversity is plurality. Hannah Arendt wrote:
‘Politics is rooted in the indisputable plurality of people. [...] Politics is an expression of the coexistence and cooperation of the different.’ 
Plurality is a political concept. When the many voices of the de facto diversity receive a political language and their discourse is heard, when those who have been made others receive political rights and political options for codetermination, diversity can become plurality. Such plurality is more than just freedom of opinion. The more social positions, demands, and interests that have been excluded or made invisible are brought into the political process, the more pluralistic the political system will become.
Education that seeks to reflect political plurality is closely related to difference conscious social and education policies. Its didactics, institutions, canon, and staff composition will then also need to meet the standards of plurality. This is a particularly difficult undertaking in adult education – above all because of its decentralised structure.
One example from the field of political adult education illustrates this well. In my opinion, attempts to account for the growing political diversity starting in the 1970s that led to key standards such as the Beutelsbach Consensus and the more recent Frankfurt Declaration  are unable to entirely account for the continued diversification of society since the 1990s, for which the political voice is still fragmented. We need a new standard that reflects and promotes this budding plurality and many experiments that help to turn good will into education that takes account of differences.
