Another thing is that fiction provides a unique opportunity for revaluation of all values (almost according to Nietzsche’s project), or at least for evaluating different versions of the hierarchy of values and preferences.
But in any case, there should be a certain binding to ones or the other values accepted as default, because otherwise it would be impossible to perceive new, unusual and unfamiliar ideas as essential.
The utmost escapism is inevitably related to the main flow of life – the question is always about the desire to escape from something and the destination of running.
However, there are things which one can never get away from – himself for example, – and this turns out to be the most important, the most valuable thing, and that is what one has to deal with in the long run, but in order to find this balance, everything has to be checked for strength and sustainability – as well by the means of fiction.
Of course, the diversity of aspects of fiction capabilities listed above is in no way exhaustive.
At least two relatively autonomous aspects are worth mentioning separately, as they are distinguished on other grounds.
The social aspect of science fiction – and probably the most significant behind its limits – is primarily associated with the expression and comprehension of the ideals of social order (directly and primarily in the form of various utopias and anti-utopias – respectively, the positive and the negative), and also provides the development of the future, with a reinterpretation of the past (alternative history), with recovery of the socio-cultural condition of the world and forming human relationships, not to mention overcoming xenophobia and tolerance development.
For example, Rorty highly appreciates the role of fantastic experiments carried out in the novels of George Orwell, which help to understand the nature of a man, the formation of the modern concept of a fair society and avoidance of violence.
By the way, the heated debates on the program of so-called gender studies elegantly complement the fictional models of societies, cultures and civilizations, built on a completely different (from what we are used to) principles: it is not just about the possibility of existing of other life forms (in one case – the androgynous, and in the other – proclaiming and accepting dominance of homosexual contacts over heterosexual), but also more exotic ways of existence – the robots, for instance, which also happen to be discriminated like women, blacks, gays, children and other peculiar characters.
