That's deep. However, that's looking to the ideal of the slinger. It's like Plato's theory of the forms. That there is One superior form of everything by which everything else is defined and to which everything else defined by it is inferior. For example, when we would think of "THE Slinger" we would imagine an slinger of immense strength and speed, able to launch stones of any size great distances with perfect accuracy. That is the ideal of The Slinger that any practitioner of the art of slinging strives to achieve, and as slingers, we are defined by the perfect form of The Slinger, to which we are always below, yet strive to reach. As such, the will to become The Slinger is a noble will that drives one to excellence, but to become that Slinger is impossible.
In other words, the perfect slinger has the muscular power of Arnold Schwartzenegger, with the throwing arm of Randy Johnson in his prime, the accuracy of a Benjaminite or Balearic slinger, and the rapid reloading ability of a shepherd.
However, the will to perfection is great, but without practicing one's ass off to get a strong and fast arm, it's all for nothing.
