At best that describes 2 out of 6 of mine. At worst it's zero. You seriously needed to heed my advice when I said that this was not going to get you anywhere.
Let's talk about what it means for a
thing to have a
purpose. Oooooh, and I'll take a shot at some of our car enthusiasts with this one while I'm at it.
Does a sports car have a purpose? Let's take a specific sports car, like a C6 corvette. What is its purpose? To be driven fast right? I mean that's what it's good at is it not?
Not so fast (sorry for the pun). When the C6 is first sold, it's sold by the company that designed and manufactured it, to a consumer who purchased it and effectively financed its design and manufacture. So which of those two parties gets to say what it's
for? The company that made it? Or the person that it was made
for? What if they don't agree?
Let's say GM thinks the purpose of the car is to go fast (it doesn't, it says the purpose is to turn a profit, but let's say it does). And let's say the buyer thinks that the purpose is to turn a profit (this is an ironic example). So GM says "we built this car to go fast", and the buyer says "thanks for the car, I'll be shrink wrapping it and putting it in the basement for 50 years and then selling it for more". Who is right?
Let's say that two buyers disagree.
GM says "we built this car to go fast" and sells it to two people. The first one says "I bought this to turn a profit" and the next one says "I bought this to go fast". Now is it built to go fast? What if GM says "we built this car to turn a profit" and sells it to two people. The first one says "I bought this to turn a profit" and the next one says "I bought this to go fast". Now is it built to turn a profit? What if one buyer just wants to look at it? What if one buyer wants to review it? What if one buyer wants to reverse engineer it for the purpose of designing a better car for a different company? What if one buyer wants to race it? What if one buyer just wants to look cool in it but doesn't actually want to go fast? What if one buyer wants to crash test it?
What if GM says "we built this car to satisfy the obligations for a racing event which we want to enter"? What if GM says "we built this car to show the concept of a design we're thinking about maybe someday building differently?" What is the
purpose of the car? There are a lot of competing theories here.
Here's another competing theory, which is probably one that you're thinking about right now and using to argue with me in your head. What if the purpose is the objective that the engineers who designed it had in mind? So then the purpose of the car is to go fast right?
Well....
That depends on the engineer. Some of the engineers were probably focused on ride quality, or safety, or longevity, or gas mileage, or meeting indicator regulations. And of course some of the designs were borrowed from previous cars. Which means that if you're going to try to borrow from the minds of the string of engineers that contributed to the design of the car throughout the decades, you're going back to the mental objective of engineers who designed some of the very first modes of transport. Now, let's say that the engineer who first designed the component and the engineer who decides to incorporate that component disagree on what it was for! So let's say for example that the first piston design was for pumping water in a garden. But some moron at GM thinks that the piston is for making a car go fast. Which one is right?
Guns are not different from cars in this conversation. The design of a gun (like cars) has grown and changed over the years, modified by countless engineers for various different purposes, including for ergonomics, longevity, weight, cost, and to satisfy regulations. The modern gun design has components in it that are nothing like the first guns, and they operate very differently on the whole. Not at the most fundamental level of course, but then at the most fundamental level they operate like cars, using an explosion in a cylinder to convert chemical potential energy into translational motion.
So what is the "purpose" of an object? Is it what the engineers had in mind? Well, no. Because no one person engineered it with a single goal in mind. Many engineers contributed in lots of ways for lots of reasons. Is it the purpose of the "first" example of that object in history? Well that just kicks the same problem to a different question, and also how on earth would you figure out what the "first" one was? You'd be putting more weight on one component of the design (which survived revisions) while ignoring some other component (which did not). Is it the purpose of the designer or manufacturer? No, because designers and manufacturers of guns have lots of different purposes. Most of which are usually to make money, but some of which might be R&D, tech demonstrations, or simply reducing cost for for one model compared to another (or to make it good at sport, or for display... etc. etc.). And different designers and manufacturers might disagree from one gun to the next, and between each other when comparing different models. Is it the purpose that the buyer wants to use it for? Well that's a tough one too, because buyers disagree all over the place on what guns are for, but also the gun was produced with knowing exactly what the buyer was going to use it for.
So what is the purpose of an object? It doesn't have
one purpose. It exists because of a web of interactions of individuals which each have their own motives.
