It's a classic phrase, but is there a word that encapsulates the sentiment of this idiom?
Edit:
Single word isn't a requirement, I'm just looking for a concise and eloquent alternative.
I don't have a specific sentence in mind; I think it's a beautiful idiom and I'm simply looking for alternatives to it.
In my opinion, context isn't required. Nonetheless, I've been asked to provide some degree of specificity: the first example that always comes to mind is the scene in The Matrix where Cypher is eating a steak and talking to the agent. Cypher says:
"I know this steak doesn't exist; I know that when I put in my mouth, the Matrix is telling my brain that it's juicy and delicious. After 9 years, you know what I realized? Ignorance is bliss."
