ALL IS NOT WELL.

The article focuses on the 1755 Lisbon earthquake, a catastrophic event that devastated the city and challenged Enlightenment-era beliefs about divine providence and human suffering. The disaster, which included a massive earthquake, tsunami, and fire, caused widespread destruction and tens of thousands of deaths, prompting intense philosophical debates. Voltaire criticized the optimistic view that this was "the best of all possible worlds," while Jean-Jacques Rousseau attributed the tragedy to human failings such as poor urban planning and moral corruption rather than divine punishment. The earthquake also influenced urban reconstruction under the Marquis of Pombal, who implemented innovative anti-seismic architecture and modern city planning. This event marked a significant turning point in European intellectual history by questioning traditional religious explanations for natural disasters.
