Subject and object Are all things either objective or subjective?
No. This distinction may be sufficient for everyday use. But when we want to explain a cultural phenomenon, this dichotomy is too simplistic, because cultural entities are socially constructed, they are neither objective nor subjective, but someting in between.
An *objective* phenomenon exists independently of human consciousness and human beliefs (be it an individual or the whole of humanity). Example: Measles is caused by a virus, tuberculosis is caused by bacteria. These are facts, representations of a reality "out there", whether we believe or know this reality or not.
The *subjective* is something that exists depending on the consciousness and beliefs of an individual. My political opinion, my personal tastes, my memories... all these "things" are subjective, they depend on a subject, in this case it is "me". If I think that "Life of Brian" is the funniest movie ever, so be it, nobody can prove my wrong.
But most cultural entities are are neither objective nor subjective: they are *inter-subjective*:
"The inter-subjective is something that exists within the communication network linking the subjective consciousness of many individuals. Inter-subjective phenomena are neither malevolent frauds nor insignificant charades. They exist in a different way from physical phenomena such as radioactivity, but their impact on the world may still be enormous. Many of history’s most important drivers are inter-subjective: law, money, gods, nations.
Similarly, the dollar, human rights and the United States of America exist in the shared imagination of billions, and no single individual can threaten their existence. If I alone were to stop believing in the dollar, in human rights, or in the United States, it wouldn’t much matter. These imagined orders are inter-subjective, so in order to change them we must simultaneously change the consciousness of billions of people, which is not easy." (from "Sapiens" by Yuval Noah Harari)
Take for example law or language (e.g. the meaning of words): It is obvious that they are not objective, because they depend on the minds of human beings. And they change, be it slowly and unintentionally, or per *fiat* (a legislative authority promulgates a new law or changes an existing law). But they are not "subjective" because a given subject cannot change them (unless we espouse the rather mystical idea that a whole society is a "subject"). From the point of view of individual subjects (the only kind of subjects that exist), laws or the meanings of words (or grammatical structures) are "quasi-objective", they exist "out there" and they continue to exist even if I stop believing in them, because they exist in the minds of thousands, maybe millions or billions of other people.
The realm of inter-subjective entities, or "imagined orders", as Harari calls them, is the sphere of cultural conflicts, because what is "objective" for group A is "subjective" for group B. Religions are the best examples for this kind of conflict. Countries are another example. Before a dedicated group of like-minded men created the United States of America, this "thing" did not exist. Their challenge was to convince enough other individuals of their belief. If they had failed and if the idea of an independent country called USA never had taken root in the minds of a critical mass of other men and women, the USA would not exist. But this idea did take root in the mind of billions of people (is there anyone who denies its existence?), and therefore its existence is *quasi-objective*; not *really* objective, because countries - unlike true facts - can cease to exist (Soviet Union, Yugoslavia...). Mostly these "imagined orders" do not simply vanish but are replaced by another imagined order (the Deutsche Mark ceased, but was replaced by the Euro)
The point is: the "essence" of a belief by thousands or millions is different from the "essence" of a personal thought that happens to be in my mind. I can have a moral intuition ("That poor beggar! I'll give him a euro" ), but that is different from a moral rule: "Thou shall give a tenth of your income to the poor!" Private thoughts and intuitions come and go, but moral rules can - and they did - stay and evolve: from fuzzy rules shared by a tribe, to a written law (e.g. in the codex of Hammurabi), to a full-blown Constitution which serves as a kind of OS for a whole society of 350 million individuals. It would be ridiculous to call a constitution "subjective", and if it is not, then the moral rule shared by a tribe of 300 is not either
Collectively shared ideas often evolve to form institutions (courts, governments, corporations, councils...) which in their turn can be studied as if they were just as objective as the moon or a virus (there is vast literature on Canon Law), whereas their "objectivity" derives entirely from the shared belief of thousands or millions of minds (the objectivity of the virus does not)
Therefore it would be a great progress if everybody acknowledged that the dichotomy objective/subjective is dangerously simplistic and cannot be applied to everything (to every thing), but that a lot of "things" we are talking, discussing, arguing, fighting about are neither nor, but *inter-subjective* or social.
