Kant is best known for his rigorous examination of the limits and scope of human reason, encapsulated in his seminal works such as "Critique of Pure Reason," "Critique of Practical Reason," and "Critique of Judgement." He proposed a framework that sought to reconcile rationalism and empiricism, asserting that while our knowledge begins with experience, it does not arise solely from experience.

Kant's moral philosophy, particularly his categorical imperative, emphasises the importance of duty and universal moral principles, influencing countless ethical theories that followed. His ideas have since permeated various disciplines, making him one of the most influential philosophers in history. Kant's legacy continues to challenge and inspire deep contemplation of knowledge, morality, and aesthetic appreciation, prompting individuals to consider the foundations of their beliefs and actions in the pursuit of a fulfilled life.
