You've Gotta Have Heart! and artistic ability to prove it

"We took away your art because we thought it would reveal your souls. Or to put it more finely, we did it to prove you had souls at all." Ms. Emily Page 260
In the novel artistic ability is the ultimate determinant of whether or not clones have a soul. Many people in real life believe that doing artistic activities reveals a piece of your soul and in some ways it does. But does a lack of artistic ability really mean you don't have a soul? I don't think so. Though I'm all for artistic things (being that I am not very athletic) I don't think that people who aren't good at art aren't fully human. Tommy struggles with this and works all his life to try and be good at art, but in all honesty he seemed most happy when he was playing football. That's what he was good at too. Although I don't think athletic ability reveals soul either. What I really think determines human soul is being truly passionate about something and loving and caring for something and someone. Tommy cared about football but then he also  truly cared about his art as well which is what made him improve. Also his love for Kath made him work harder at it as well. That's what truly makes a person a person.
