At one point this word was probably used as an epithet. I am certain if you scour the pages of Edith Wharton’s or Booth Tarkington’s novels you will run across this word being used to describe one of the characters. It would probably be used as a minor epithet to describe a character who committed some peccadillo, but I think this word can evolve to describe someone who is an iconoclast. If you think about it Einstein, Buffet, and Jobs were all scapegraces in their own way. They defied conventional wisdom, followed their wild passions recklessly, and because they believed in their convictions and passions so fully, they stood out from the crowd of people surrounding them and created revolutionary ideas and products that have changed the world.
I don’t think it’s a bad thing to be a scapegrace; I welcome it and see it as a challenge. The ability to go against the grain with temerity and courage. It is undoubtedly difficult to strike out on your own, become a scapegrace, and be a little wild in your thoughts and ideas, but it seems as though that’s the key to being an outlier.
