The quote "What can I know? What ought I to do? What can I hope?" is attributed to the 18th-century philosopher Immanuel Kant. It encapsulates three core philosophical questions about knowledge, morality, and hope. Kant's quote reflects on the limits of what we can know, the moral imperatives guiding our actions, and the nature of hope for the future. His philosophy suggests that while our mind actively shapes our understanding of the world, we must critically question our knowledge, act ethically, and maintain hope as a driving force in life. This quote serves as a profound starting point for examining our beliefs, actions, and aspirations.
