Why did Captain Beatty believe books should be destroyed in Fahrenheit 451?

In Fahrenheit 451, Captain Beatty believes that books should be destroyed because he views them as a threat to society. He argues that books contain dangerous ideas and knowledge that can lead people to question the status quo and challenge the government's authority. Beatty believes that a society without books will be a peaceful and harmonious one, where everyone is content with their lot in life and does not ask too many questions.

Beatty also believes that books are a source of unhappiness. He argues that people who read too much become dissatisfied with their lives and start to think critically about society. This can lead to unrest and rebellion, which Beatty sees as a threat to the stability of the government.

Beatty's belief in the destruction of books is based on his desire to maintain control over society and prevent people from thinking critically. He believes that a society without books will be a more docile and obedient society, where people will not be tempted to question the government or seek knowledge that might challenge their beliefs.
