You're talking about a species that has existed for 200,000 years,
More like two million, but even accepting 200,000 years, the invention of a concept in the last 3000 (1% of our existence) fits the bill for "relatively recent." Especially in the context of the Trekiverse where humans are bumping elbows with civilizations that were colonizing other worlds when humans were still trying to make fire. The Vulcans, for example, were nuking each other with ICBMs and space vessels at around the same time the Roman Empire began to assemble its first professional military.
Under the definition of a military I gave -- the institution legally empowered to defend the state -- militaries would still have existed in those contexts
Well no, because that would require both notions of organization and a concept of statehood meaningfully similar to our own. Neither concepts are applicable to pre-historic societies, in fact they're not really applicable to a number of historic societies for a variety of reasons. There are parallels you can draw by analogy or similarity--just like you can draw parallels between, say, corporate capitalism and feudalism--but the application thereof and underlying concepts are so different that it's practically apples and oranges.
The concept of a military is no more related to those concepts than the concept of liberal democracy or communism.
Nobody said it was. I said that those concepts, by at least the 23rd century, have been subject to such a huge degree of modification that they are no longer intelligible as such by OUR standards.
The idea of a military bears a closer relationship to the idea of bureaucracy than to the idea of how the government itself will be organized.
A good analogy, since the idea of a military is a SOLUTION to a complex problem much the way a bureaucracy is a solution to an organizational problem. But then, the Federation doesn't seem to be a bureaucracy either. Actually, considering the alarming lack of major Starfleet training centers anywhere but EARTH, I am under the growing impression that the Federation is a type of extremely dynamic adhocracy.
Then why has Star Trek repeatedly referred to Starfleet as a military?
I was not aware that television shows were capable of referring to themselves. Could you be more specific?
For reasons of propaganda. In reality, if the state employes a mercenary group to defend the state, then that mercenary group has become the state's military.
Unless the state chooses not to recognize it AS the military for some reason. I mean, there's legal definition from U.N. conventions (which we know in Trek has been done away with by at least the year 2079) and then there's etymology and word usage. In the latter sense it's a tad harder to define, like the difference between "executed" and "murdered".
You have also ignored the other legally distinguishing characteristic of militaries that I listed: The possession of courts-martial.
20th century legalisms were, again, rendered irrelevant by the year 2079.
Um, no, actually I call bullshit on those instances.
You're free to do so. As long as you are aware that this is, in point of fact, a disagreement between you and Star Trek.
Suffice to say: whatever the Federation uses is different enough from what WE use that it is not referred to, regulated, governed or accumulated the same way. It is "money" by analogy only, in exactly the way Starfleet is a "military" by analogy only.
And what, exactly, would you define a military as, if not the armed forces of the state?
Whatever a particular culture/state/language chooses as a way to define "military." This will vary from culture to culture and even century to century in the same culture. The concept is not specific enough or special enough that it must always exist, nor that it cannot be superseded by other concepts.
Obviously, then, when Picard is reading Shakespeare's Hamlet, he is not actually reading a play
Of course he's reading a play. That's what Shakespear wrote by the definitions of the time. And when he looks at Q wearing an old American army uniform, he's looking at a man in a military uniform, because that's what he was wearing by the definitions of the time. Of course, if Picard was reading from the script of the Kenneth Branagh movie, he's not reading a play, he's reading a script. And if he's reciting it in a holodeck simulation, it's not a play, it's a holonovel.
Plays are not movies. Plays are not holonovels either. They are equivalent, and they serve very similar purposes, but they are not the same thing. And I'm not even saying that plays don't exist in the 24th century, nor do militaries not-exist in the Federation. Just that Starfleet is no more a military than Kenneth Branagh's Hamlet is a play.
No, because an 18th century musketeer is perfectly capable of understanding that the NYPD does not defend the state but instead enforces internal law.
So does the militia. What you're missing is that an 18th century musketeer isn't going to be using terms based on definitions found in 20th century international law. And neither is Starfleet.
The term "military" means what it means
Obviously; it ALWAYS means what it means. Even when what it means changes.
there is no evidence that the definition of the term has evolved by the 24th Century.
Are you kidding? It's evolved enough since the
18th century. Why would it be the only concept in the human race NOT to evolve in the same amount of time in the future?
