I'm taking it all a little easier.
1. There is a person, an individual and a set of other people.
2. There is the physical world, objective reality, where E=mc2, where there is consumption of hydrocarbon compounds by living organisms, where there is solar radiation to the surface of the planet, etc. - with its own generally objective laws.
3. And there is also a system of symbols and interpretations, a system of instructions and narratives about how exactly one should look at oneself, and how exactly one should perceive oneself and the society one is forced to be in - mostly specifically desinforming. It's not really a system at all, it's a toxic chaotic cesspit whose parts mostly contradict each other, but conventionally it's all considered a "system".
The list of sources of the origin of this "system" of meanings is too long to cite here, suffice it to say that its components are religion, ideology, pedagogy, and of course the mass media and some more stuff.
When you say "F.ck the modern world," what exactly do you mean:
1. F.cking other people. Understandable, natural, but boring. Mankind has been doing the same thing for about the last 5000 years at least, for various reasons.
2. F.cking with objective reality. Interesting, but problematic. Questions arise: are you tired of the sun or the moon? Are you sick of breathing O2? Don't want to live in constant gravity? Do you hate Ohm's law?
3. it would be most logical to assume that you want to f.ck this system of meanings, some separate mechanisms of which have already entered so deeply into your consciousness that you have lost the memory of the entry point and consider them a part of your personality. So I have to tell you that you ought to do it almost 24/7 and maturity, independence of personality, freedom, and mental security in general depends on how successfully you cope with this task. And that's what any more or less grown-up decent person should be doing, to be honest.
I almost forgot! We are on a video game forum. Where do you think video games belong in this classification? )
