Passing Some Buck

The beast has a high type of courage -- he isn't afraid to do things he's afraid to do.In an early 1930s story in the Buck Rogers comic strip, Buck goes to Jupiter and befriends a tribe of giant wolves who live there. (Comic strip readers of the thirties must have been really good at suspending disbelief.)

The comic strip is interesting, if you’re a student of the early history of adventure comic strips or popular science fiction. If you’re looking for good art, intriguing plots, or engaging characters, you may be disappointed.

Nevertheless, here’s a pretty decent description of courage:

He isn’t afraid to do things he’s afraid to do!

It’s not courage if you’re not afraid.
