The relation between chastity and orthodoxy

"There was a direct, intimate connection between chastity and political orthodoxy. For how could the fear, the hatred and the lunatic credulity which the Party needed in its members be kept at the right pitch, except by bottling down some powerful instinct and using it as a driving force?

Coincidence perhaps?
