Initially, humans could not draw as they perceived. It was only after the discovery of perspective that they could accurately draw what they saw. Perspective was first applied to performance stages in Greece during the 5th century BC, and it was not until the 15th century that the Italian architect Brunelleschi succeeded in expressing a three-dimensional perspective on a two-dimensional plane. In the long history of humanity, the period of applying perspective is quite brief. Perspective painting represents a virtual depiction of reality. In other words, the first instance of visualizing something virtual is perspective. People speak as if the metaverse is a significant industry today, but the virtual realization through perspective began long before the digital era. Currently, it’s only visually represented digitally. Understanding the essence of this can help you mitigate risk, even as times and circumstances evolve. - Joseph’s “just my thoughts”
The hospital is where patients are healed. Therefore the hospital is full of patients. The hospital must be able to keep patients healthy and accommodate many patients at any given time. The church is a place to call sinners. There are undoubtedly many sinners in the church. But what if there are only sinners who do not repent? Filters are tools that get rid of dirty things and clean them. If we don't clean it, it's the dirtiest. "Self-purification" restores the original substance. If the instructor omits "self-purification," the absurd result will occur as in the previous example. Don't be sad or angry even if life deceives you. - Joseph’s “just my thoughts”
