We propose a picture whereby the kinetic glass transition observed in the laboratory is controlled by an underlying phase transition with unusual properties. We assume that the line of metastable liquid states below the freezing temperature ends in a fixed point, and show that this picture is in accord with a number of experimental observations, including the vanishing of the excess configurational entropy of the liquid and the Vogel-Fulcher law. Differences between this scenario and current theories of systems whose Hamiltonian possesses quenched disorder are discussed.
