there is no such thing as a personal reality, just ones perception of reality. you can call a horse a cow all day long, but a horse is a horse and a cow is a cow regardless of ones perception. reality is not based on anything but itself; we, as humans in all our intellect, can not change it-however, we have the genuis ability of aligning our reason to it's constant, unbending truth.
"Distinctions drawn by the mind are not necessarily equivalent to distinctions in reality." Thomas Aquinas
also, love trumps all.
