 Restoration in this sense is quite different from the revival of something, such as a frozen embryo, whose vital activities have been halted. Something can be revived only if it is alive—only if it has the capacity to deploy vital activities, as in the case of a frozen zygote. It is revived when it regains vitality. Something’s life can be restored only if it has lost its capacity for vital activities. Life is restored when this capacity is regained.
