> If we plot the heights of sisters against a fixed median height interval of the brothers, the point our line goes through specifies the height of the normal sister not too tall nor too short, not too domineering nor too clinging, not too glamorous nor too homely.

> Quetelet sees an identity. Our inequalities of height are, in his eyes, the result of inept measurements taken by Nature on an immutable model in whom alone she reveals her secrets, 1 m 75 is the normal height. A little more makes no less a man, but the surplus or deficit in each individual is nature's error, and thus monstrous.
