A Quote by David Berlinski on algebra and logic

The individual variables x, y, z,... now make a semiformal appearance, performing the function in logic that pronouns perform in ordinary English, the sentence "She is blonde", cognate to the proposition "x is blonde", both she and x specifying something but specifying that thing indeterminately.
