Which pattern to use for logging? Dependency Injection or Service Locator?

Question

Consider this scenario. I have some business logic that now and then will be required to write to a log.

interface ILogger
{
    void Log(string stuff);
}

Maybe this will be little offtopic, but why do we need injecting logger at all, when we can just type at the beggining of the class:

Logger logger = LogManager.GetLogger("MyClassName");

Logger doesn't change during development and later during maintenance. Modern loggers are highly customizable, so argument

what if I want to replace text logger with database?

is missed.

I don't negate using dependency injection, I'm just curious about your mind.
