let λxϕ(the ζ) represent a sentence of English containing a definite description the ζ in an extensional position.2 Then the truth conditions of λxϕ(the ζ) are correctly stated by Russell’s theory; i.e. it is true at a world w iff there is exactly one object u which satisfies ζ in w and λxϕ is true of u in w.
