Another Good Example

Suppose one man learned or was taught everything there is to know about playing music, such as how to read music, which keys produce which note, etcetera, but had never actually touched the instrument; and another man had experience playing an instrument with little to no formal instruction and learned via practice. Which of these men would be the better musician? Clearly the second man would be the best musician.

The above conclusion is due to the fact that people need experience and to learn through trial and error, rather than just being given knowledge with no application.
