"Opium and morphine are certainly harmful and addictive drugs. But once it is admitted that it is the duty of the government to protect the individual against his own folly, no serious objections can be advanced against other interventions. banning the consumption of alcohol and nicotine. And why limit yourself only to protecting the body? Are not the evils that a man can inflict on his mind and soul more serious than bodily harm? you from reading bad books and attending bad shows, from looking at bad paintings and sculptures and listening to bad quality music? The consequences caused by harmful ideologies are certainly much more harmful, both for the individual and for society, than those caused by drug use.
These concerns are not just imaginary specters that have haunted lonely thinkers. It is an undeniable fact that no paternalistic government, ancient or modern, has ever hesitated to regulate the ideas, beliefs, and opinions of its subjects. If man's freedom to determine his own consumption is abolished, all other freedoms will also be abolished. Those who naively advocate government intervention in consumption are deluding themselves by neglecting what they scornfully call the philosophical aspect of the problem. They inadvertently contribute to the establishment of censorship, the inquisition, religious intolerance and the persecution of dissenters."
