“Ignorance is bliss” is the bittersweet proverb that admits what we don’t know can’t hurt us. Here is what it means, its origin in an eighteenth-century poem, how to use it, and a few sayings that share — or complicate — its view of knowing.
What Does “Ignorance Is Bliss” Mean?
The proverb means that not knowing about a problem or unpleasant truth can leave you happier than knowing would. If you are unaware of a worry, a danger or a piece of bad news, it cannot trouble you. The phrase is often used a little ruefully — sometimes to excuse not wanting to know something, and sometimes to envy the carefree happiness of those who haven’t yet learned a hard truth.
Origin of the Proverb
The phrase comes from the English poet Thomas Gray and his “Ode on a Distant Prospect of Eton College,” written in 1742. Watching schoolboys at play, the poet reflects that they are happy precisely because they do not yet know the sorrows adulthood will bring, and concludes: “where ignorance is bliss, ’tis folly to be wise.” Notice that Gray was not really praising ignorance — he was mourning lost innocence, suggesting it would be cruel to rob the children of their carefree joy. The shortened phrase took on a life of its own.
