Its a performance enhancement.
No point in instantiating the logger if it's not going to be used!
Fail fast and get better performance ;)
Also, logging can then be enabled and disabled on a more fine grained
level, you may choose to log in a class regardless of whether logging
in the entire application is switched on or off (useful for isolating
some problems so you don't get reams of useless log information you
are not interested in).
