パングロス (Optimism) is a philosophical concept that suggests everything happens for the best in the best of all possible worlds. This idea is often associated with the character パングロス from ヴォルテール's novel "Candide." He embodies unwavering optimism, believing that every event, no matter how negative, contributes to a greater good. The term has evolved to describe an overly positive outlook that may ignore real challenges and difficulties. While optimism can encourage resilience and hope, excessive optimism may lead to unrealistic expectations and a lack of preparedness for adverse situations.
