I think that the world we live in is real. 
Instead of taking any one of the multitude of available belief systems about what is real as the defining mark, what about just accepting the reality that we have, right here in our face which we actually interact with on a daily basis? Not that there couldn't be another, more accurate reality outside of this experience, but how could we ever know? Certainly not by making something up, right? I think it is most intellectually sound to first and foremost acknowledge as real that which we can know for sure from empirical evidence within this thing which seems to be reality to us and which we call reality in every other arena except for that of philosophy, religion and theoretical physics. 

...but What If...? 
Sure, I've heard people say things like, "Well, what if all of this isn't actually here and we're just being deceived somehow?" or "What if this is all just a delusion?" or "What if the movie 'Men In Black' is right and someone's out there playing with galaxies like they were marbles and our fate actually does lie in the hands of someone or something we can't even see?" or "What if we're actually making this up and have forgotten that fact and we're really sitting in some insane asylum somewhere walking around banging our head on a wall asking for more pudding?". 
    Sure, I hear ya. Of course those scenarios are "possible", and it is also possible that we're all just experiencing one big community dream and our bodies are actually lying, comatose, next to each other in our own separate bio-stasis maturation chambers in the power plant from the movie "Matrix". Not only are those scenarios possible, but so are billions of scenarios that no one has thought up yet. 
    The possibilities are literally infinite. The boundaries of imagination and creativity are the only limiting factors in the world of make-believe. Yes indeed, I suppose that all of these scenarios and many others are possible, but we can't be any more certain about any of them than we can be about this reality right here and now that we already have to work with. 

Can we really pretend our concept of reality into existence? 
Maybe it'll come about if we just believe hard enough? Who sells us on this stuff and why are we so prone to buy it when he comes to the door? What is it that predisposes us to believing in the first place? [This is a concept I hope to study more about at some point soon so that I can start filling this section of my site with my findings in that particular area of thought] What I really want to know is, what the hell is so attractive about pretending that our minds turn to mush at the thought of a better life or a more enjoyable or subjectively palatable explanation for the way things are? Not that I think there's anything intellectually unhealthy about imagining a better life. I don't. 
    Imagination and creativity being applied to these kinds of things quite often helps us come up with more healthy and more enjoyable ways of interacting with each other in society. However, I do think there is something fundamentally unhealthy about pretending that we really know for sure that it really is out there somewhere or gambling on the possibility of it being real to the point that we disengage from full interaction with knowable reality, i.e. just waiting for heaven or some other such nonsense like I saw all too often back in my believing days in most of the Christian communities I spent time in? 

Where does it stop? Which alternate reality are we going to latch onto today? Why would we give something mysterious or unknowable (regardless of how fantastic or wonderful or "believable" it seems) more sway in our minds and more prominence in our lives than that which we can actually see and touch? Why is it so unexciting to acknowledge the limits of our ability to know for sure? Why can't we just let our conceptual hopes and dreams be just that and let knowable reality be just that. Why confuse the two?
