Everyone leaves the beaten path only to fall into the same ditch.

From Deceit, Desire and the Novel: Self and Other in Literary Structure by René Girard.  On the power of conformity.

Modern society is no longer anything but a negative imitation and the effort to leave the beaten paths forces ev­eryone inevitably into the same ditch.
