Freud sounded super-foolish this way.
He hypothesized that couples in the Victorian age had psychological troubles because their puritanical upbringing made them despise or fear sex.
Then Burmese author, Pi Moe Nin argued that if it was so, those Victorian parents must have been more persuasive and convincing than Lord Buddha Himself. Buddha taught and implored people to abstain from even sexual thoughts, and failed miserably. But these parents had succeeded in just one generation!
Maybe Sir Freud forgot logic and clear think during the hypothesis-formulation stage of his research.
