A THING (X) doesn't have any inherent properties such as objective versus subjective. A THING (X) is never objective. A THING (X) is never subjective.
The WAY to look at/interpret the THING (X) can be done either through an objective view or a subjective view, or both.
The thing itself doesn't, but in our heads it does.The thing is nothing more than an object. In our mind we make a subject of it, trying to get as close to the object as we can. Those two can get very contradictory.
Infinity is an abstract concept, it is not a fact. And, I wouldn't call infinity, inherently, a "belief" either. It's a tool to explain limits. So, I don't really understand your rationalization above.
That's why I said "if we agree on". I'm not saying it's "true". I was just playing with the thought, what
if it were limitless. I know a lot of people who don't believe in infinity. They think of everything as limited. I'm not sure though "believe" is the correct translation of the dutch word I had in mind xD So if I said something strange, I blame our language differences.
The object isn't doing two different things. Two different observers are creating two different results as the observer is a function of the apparent velocity. Both are true.
But by producing two different results by doing one thing, isn't there doublethinking going on? However.. Not that it is that contradictory to say "the object seems to be having x velocity for me and y velocity for him". Both seemingly velocities are true. Could this be nothing more than a rationalization of doublethink?
Nah.. as you said. It isn't a property.
Quantum mechanics is not doublethink. They're similar in some superficial ways, but not the same.
It would be closer to doublethink if you said "the electron is a wave. It is not a wave", although doublethink usually refers to things that are 100% objectively true, whereas much of quantum mechanics is still theoretical. It's only doublethink if the things are objectively contradictory, and a wave-particle is not inherently contradictory, although it is difficult to understand.
So it isn't contradictory that the electron is going through both holes? There's not much theory to that. It was an experiment by Young (I think) in the.. 19somewhat(?). What he observed was contradictory to our beliefs.
Al though quantum mechanics is more of a duality than a contradiction. The thing about quantum theory what made me think of doublethink was the importance of focus. If you focus on one thing, that thing is true, if you focus on another, the other thing is true. If you focus on the electron itself, it is a particle and you don't see much of the wave-behaviour. If you focus on the trajectory it takes, it is a wave and you don't see much of the particle it is. But both are true. You just have to relate the two observations to know it is both.
