Isn’t there something better and more individual to do?
Yes there is always. We can be for example idle, calm, sleeping, dreaming, lying around, freely associating. Or moving, dynamically hopping around, dancing, spiraling, etc.
We also need the constructed securities of ideologies and their re-assurement (of our constructed „self“-pictures and our subjective world-view/ordering).
But that’s not all we can. We can have (and unconsciously and consciously we timelessly „always“ -> parallel to all contingent ideological „aussurance“ we have) transcendence of every contingent fixation. No ideology is really closed, basically everything that potentially is, is always parall to all other things.
Parallelity makes life plural.
