18th-century novels created a new literary form that explored the passions and ordinary lives of individuals. This cultural shift elevated the private sphere, previously considered unimportant, into a subject of value, fascination, and social anxiety.

When communities object to surveillance technology, the stated concern is often privacy. However, the root cause is usually a fundamental lack of trust in the local police department. The technology simply highlights this pre-existing trust deficit, making it a social issue, not a technical one.

The right to privacy originated not from a demand for personal space, but as a necessary political compromise to end centuries of religious bloodshed. Granting freedom of conscience in private paved the way for broader personal freedoms.

We spend more time alone due to structural factors and technology that enable avoiding interaction.

Long novels, now the gold standard for deep focus, were once considered dangerous “junk food” that distracted people from prayer and duty. This historical pattern suggests our current panic over digital media may be similarly shortsighted and lacking perspective.
