I passed out laser pointers to my class, and asked them to point "up". Half of the students passed, coincidentally they were sitting in front. Students sitting in the back, could see where others were pointing their lasers, and copied them, pointing their lasers at the same spot. Up, is clearly defined, but still some people have a hard time grasping the concept, or rationalizing the idea that up is different for everyone on the planet.
The same goes for beauty. Each of us is capable of recognizing beauty, and we all have different interests.
Don't be like those students who failed my class, think for yourselves.
