In our metatheory approach, we assume a process pattern of cognition and action, which regards the handling of paradoxes, polarities, ambiguities, antagonisms and distinctions as core competences of viable systems. Polarity describes the observation that two parts together form a unity, that neither of the parts is possible or conceivable without the other part. Nobody can think about light without bringing with it darkness, no one can hold on without also letting go. A distinguishing feature of polar unity is that each of the two poles is of equal value and importance, that they complement each other and that they do not stand in logical opposition. Therefore, one cannot destroy one of them without also harming the other, i.e. the whole. And – what is just as important – one can only live the one of them well, when one can also live the other well. If someone is better at holding on than letting go, it will, in the long run, lead to cramps. A functional interaction with polarities consists of keeping both poles in play. Since a game is a time-dependent event, it means that one must handle the poles sequentially. It is not possible to breathe in and out at the same time. However, one can (and must) do it one after the other (competently). As one is usually more talented with one pole than the other, in a psychological or organisational context, this can be quite a challenge.
