Idealism is a philosophy that believes that the objects we perceive through our senses are actually ideas that exist within the mind rather than independent material objects. It holds that reality consists of ideas and the physical world is either mental construction or a product of perception. Idealism pursues elevated ideals and conduct by envisioning things in their ideal form and pursuing one's ideas and ideals through art, life goals, relationships, and religion. However, it raises issues around distinguishing perception from reality and whether sense data corresponds to real external objects.
