Neo-Kantianism is a philosophical movement that emerged in the late 19th century as a revival of Immanuel Kant's ideas. It is characterized by a focus on the methods of philosophical inquiry and a commitment to the use of reason and logic to understand the nature of reality. The movement has been described using a variety of synonyms, including post-Kantianism, new Kantianism, and transcendentalism. Some scholars have also referred to the movement as critical philosophy, while others have used the term idealism to describe its emphasis on the role of ideas in shaping the world. Despite the various labels applied to this philosophical movement, its commitment to the Kantian tradition is central to its identity and influence on modern philosophy.
