Appearance vs Reality in Macbeth

Ever wondered why your parents tell you not to judge people by their looks? Shakespeare was exploring this exact idea 400 years ago in Macbeth. The play is built around the terrifying idea that you can't trust what you see.

Lady Macbeth's famous line "Look like the innocent flower but be the serpent under't" perfectly captures this theme. She's telling Macbeth to use a simile and juxtaposition - appear harmless like a flower whilst being as deadly as a snake. The serpent is a clever biblical allusion to the devil in the Garden of Eden, linking deception with evil.

The witches set this tone from the very start with their paradox: "Fair is foul and foul is fair". This contradiction becomes the heartbeat of the entire play. When Macbeth echoes this with "So foul and fair a day I have not seen," Shakespeare shows how the main character is already caught up in this world of confusion.

Key Point: Duncan himself admits "There's no art to find the mind's construction in the face" - even kings can't tell who's trustworthy just by looking at them!

The theme reaches its peak when Macbeth decides to "play the humble host" whilst planning murder. The alliteration emphasises how fake his friendliness really is. Meanwhile, Donalbain wisely warns "There's daggers in men's smiles" - a powerful metaphor showing how people can hide murderous intentions behind friendly faces.
