We can live in the chronological time where we consider one year, month, day ago and the next year, month, day. But we can also live in present where we consider next second, minute and last second, minute...

Hi Daniele,

"homeless" object lives into our fictional narratives   They exists in our narrative worlds.  It is a uniquely human capacity to create such object.  But the reason we can do that is because it is because we can create narratives.  We can do that because we have this capacity and we have it because we are humans and we are  humans because some primates began to access the very mechanism by which our body interact with the world.  From this access we could self-enact action.  We learned to do this because we began to sing and dance together.  We start doing that because it is a long story.

Regards

This is a good question, which has no straight up-or-down answer.    In addition to the incisive answers already given, there is a bit more one say about the invention of reality.

The idea of inventing reality came into prominence with the astonomer

B. Gregory, Inventing Reality: Physics as Language, Wiley, 1988

Gregory writes about how physicists use the language of physics such as quantum mechanics, special relativity fields and quarks.   Gregory describes physics as the drive to predict the behaviour of a world stripped of most of its complications (p. 197). 

This is a language-based understanding of the evolution of physics with the creating of new languages (and symbols) to accommodate our changing world views and their incremental evolution.

Personally, it depends on your definition of "reality".

I mean, the idea of taking models and simulating them is done by computers all the time, is that a reality?  I mean, one of my hobbies is making video games.  You make the logical rules, and the program is guided by those rules to simulate what could be considered the "reality" of that game.  Is that a reality?  Does something need to be conscious to be able to determine if it is a reality or not.  What is conscious in general?  Or is it that we must model everything to create our own "reality"?  Or is the definition of reality relative, i.e, based on our perception.  I'm pretty sure depending on your sanity level (or even when one is "normal"), if that is the case, perception can vary.

I just see this really as a problem of defining what reality is.  In some contexts, in human language it's context changes based on the topic.  You end up with more problems than answers, which makes it not very productive to be honest.
