Rarely does an erected flag fly alone. An invisible wind moves it, meaning an external force. When the wind blows, flags flutter, dust rises, and laundry dries. Many changes occur in response to one external factor, but we cannot see the cause. Eyes capable of reading invisible external causes can respond to a world of rapid change. We cannot attribute a cause solely by observing a phenomenon; instead, we must recognize a specific pattern across multiple phenomena. The ability to detect hidden commonalities is a form of wisdom. - Joseph’s “just my thoughts”
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
