Philosophy is the love of wisdom, the search for knowledge about the world (scientia) and how to act in practice (phronesis). Civilizations tend to divide philosophy into their own peculiar domains. There is no universally accepted structure of philosophy or complete philosophical system. Eastern philosophy focuses on how to live, the Roman subject of ethics, with some degree of explanation for the natural world. Yet they all separate philosophy from the practice of developing technology (techne). Western philosophy, in the Roman tradition, is by far the most systematic in its treatment of knowledge and wisdom.
