Art or Science?

Is love ever not an act of faith?
Is there some equation to replace the inner workings of the heart?
Is love science, or is love art?
Many would say both play an equal part.
Either way, it comes down to the leaping,
To find out if a love’s worth keeping,
An analysis of what could be,
Then you have to close your eyes to see,
Walk slowly to the edge with me,
Take my hand,
And jump.
