Reality's a Fallacy

You chose the reality you live in. Every person on the planet has this power. Imagine a glass of water that contains a liquid equal to half its volume. This glass of water is often presented to us with only two options. Now which option you chose does give some indication of the reality you’re living out of but I think there are more than two ways to think about this glass of liquid. 

                ~Philosophically, there is no glass. 

                ~Symbolically, what does it mean to me the observer? 

                ~Scientifically, what is it, exactly? 

                ~Politically, how can I use this glass and its contents to my advantage? 

                ~Mathematically, half empty is equal to half full; it is the same amount of liquid in ratio to the   volume available. 

                ~Physiologically, it will refresh no matter how much there is. 

                ~Sardonically, what’s with the stupid glass, aren’t there better things to talk about. 

SIDE NOTE: If we're going to get literal, the glass is completely full of something unless it's in a vacuum.

There are more options I’m sure but you get the idea. We are limited only by our own perceptions. Get unreasonable.* What are you going to do with that glass and its contents?

*"The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man." 
-George Bernard Shaw
