It seems to me that this question was “biased” toward one brancyh of philsophy: Politics
individutalism is a metaphysical concept because it pertains to how things existi in general. You must have one person before you have a society. You must have one wolf before you have a wolfpack. You must have one flower before you have a garden. You must have one grain of sand before you have a beach. A journey of 1000 miles begins with one step. A journey of 1000 light years presupposes that the journey of 1000 miles took place which presupposes that one step.
In all cases the individual unit per-exists and defines the group. whether we’re talking about human, animal, plant or inanimate. Even water exists in molecules befor all else, the same is true of air. When you count, you count by one’s before you count by two’s, three’s, ten’s…
To be so over-arching and integral a part of the existence of all things. this must be built into the way the world works. That is the province of Metaphysics.
This is why there can be no ethical or political “defense” of individualism: it preceeds them. Morality regulates the behavior of…individuals. Politics organizes…individuals. Ergo they require the pre-existence of individuals. what if there were no individuals to behave; then where is morality? what if there were no individuals to organize into communities, regions and nations; then where is politics? LIke, Nowheresville, man.
If this were true, then why is every current form of government either totally collective, or geared toward the collective or as with the case of the USA, gradually deteriorating back to statist/collectivist rule over individuals where lip service is paid to individual rights but the actual government structure does not actually and never has actually and totally respected those rights?
My thinking is that a new kind of government which truly acknowledges, respects and protects individual rights ought to incorporate that purpose into its name, so as to never forget it. Hence my suggestion of the term Individualism. I’m open to discussion on which form of the word Individual (individualistic, individualized, individual, just for examples) might be best.
Part of this is a marketing concept. People now have the label “constitutional republic” in their minds as yet another system that doesn’t work. Even the best example, the US government, is almost universally panned. The original achievement is fading if people can even identify what it was.
I do realize that the true culprit is not “government” but rather the subjective laws that government is asked to enforce.
Maybe Individualist Government doesn’t really work as a name for it. I was thinking that since nobody is permitted to initiate force, not even the government itself, individuals are free to determine the level of government protection they need/want. Their individual rights are respected and protected under such a government. That was my thinking.
