Subtitled ""Science and Technology Versus Communism,"" this book investigates the socio-political role of the Soviet Union's new managerial, scientific, and intellectual classes. it is, overwhelmingly, a sanguine picture that Professor Parry has assembled. ""The Party is retreating high and low,"" he finds. ""The Party knows it is behind the new times and cannot catch up.""
