When Did Idealism Begin?

Idealism as a philosophical movement began in the late 18th century, particularly with the works of German philosopher Immanuel Kant. His "Critique of Pure Reason," published in 1781, laid the groundwork for later idealist thinkers, including Johann Gottlieb Fichte and Georg Wilhelm Friedrich Hegel. These philosophers expanded on Kant's ideas, emphasizing the role of the mind in shaping reality. Idealism contrasts with materialism by prioritizing ideas and consciousness over physical matter.
