I feel that there is a time and a place for everything. Beliefs and theories are tools that I use to gain one advantage or another.
What I'm trying to say is that sometimes it's more beneficial for me to view my hard floor as actually being a hard floor, while at other times it's more beneficial to view it as something other then what I percieve it to be.
As for what's True and what isn't...well, I really don't care at this point in my life. It's more useful for me to utilize that which produces the desired results rather then to use that which I see as being Truth. After all, the Truth might not work to my advantage (and I realize that in the eyes of a Taoist this is probably a very crude and/or ignorant statement, but so be it).
Ending notes: This little rant of mine might not be very Taoistic, but it makes sense to me nonetheless. Also, I just finished reading the Tao Te Ching and Chaung-tzu about two or three days ago. I'm obviously no expert on Taoism, but I at least have a foundational understanding of the path. Very enlightening texts, I'd recommend them to anyone, regardless of one's religious influences.
