How did Immanuel Kant respond to the debate between empiricism and rationalism?

Immanuel Kant addressed the debate between empiricism and rationalism by proposing a synthesis known as transcendental idealism.12

While empiricists argued that all knowledge stems from sense experience and rationalists maintained that some knowledge is gained through innate intellectual insight, Kant argued that human knowledge is a mixture of both. He famously asserted that "thoughts without content are empty, intuitions without concepts are blind," meaning that while knowledge begins with sensory data, it requires the mind's active contribution to become intelligible.231

Kant’s "Copernican revolution" in philosophy posited that the mind does not passively conform to objects; rather, objects must conform to the mind’s inherent structures. He identified these structures as:24
* Forms of sensibility: Space and time, which condition all sensory experience.25
* Categories of the understanding: Pure concepts, such as causality and substance, which provide an intelligible framework for experience.25

By arguing that these categories are necessary conditions for experience, Kant explained how synthetic a priori knowledge is possible, effectively bridging the gap between the two traditions.24
