We consider a new mechanism for dynamical symmetry breaking of the electroweak symmetries involving condensates of fourth-generation quarks and leptons. A dynamical generalization of the seesaw mechanism is proposed based upon the BCS theory in which a neutrino condensate gives rise to right-handed-neutrino Majorana masses and all associated spin-zero bosons are composite. The fourth-generation neutrino is naturally heavier than {ital M}{sub {ital Z}}/2 and the scale of new physics is bounded above. The renormalization-group equations for the effective Lagrangian of this model are derived and used to solve the model. Implications for neutrino masses are discussed.
