The definition of the word is agreed upon, and people use the term "present" quite frequently. If you don't believe me, you ought to look the word up.
Quote:As two observers can not agree on events being in synch, or even on how long an event lasts, due to relativity,
This is clearly false. Of course people can agree on events and their timings. You and I can both look at a watch and agree that X person was at Y location at Z time.
Quote:Sure, it does exist as an abstract notion within the mind of each person. But such is the case also for unicorns, God, and Satan.
There is of course the concept of "present" which exists, but then there is also the exact moment that the person who uses the word is referring to (which is not the concept). Just as I can have a concept of an elephant, but the elephant is not my concept.
Also note that if unicorns, God, or Satan did exist, they would not be concepts. I hope we're clear about this. There would of course be concepts of unicorns, God, and Satan, but as noted, the concept is not the thing referred to.
Quote:The point is that, according to physics, there is no "exact moment" that we can call the present. So, if you're claiming that "that moment did exist", I will ask for your proof, and you will not be able to come up with any.
I think you understand how the phrase "the exact moment" is used in language. You'll ask proof of what exactly? That I perceived a certain moment? I could come up with loads of evidence that I perceived something at some time, just as you can. It's obviously situational.
To be consistent, you must not believe countries, states, government or really any abstract notion exists. If I tell you Poland exists, and you responded consistent with what you were just alluding to, you would say, "Well, since there is no "exact location" which is Poland, it does not exist. Where does Poland start and end; you can provide me coordinates, but that's not enough!".
I know what Poland is, just as you do. I know what governments are, just as you do (just examples; there are plenty). And if someone says "now" or "the present", I believe you understand what they mean. I believe you already know this (I'm just reminding you) - you have the ability to understand what people mean when they reference times. For instance, if your friend asks you to be at the park at 1:00pm tomorrow, I'm sure you could understand what your friend means. And tomorrow at 1:00pm when you show up, you could say to your friend, "We're now at the park", and I'm sure he would know what you mean. I don't understand what is confusing about this.
