[T]hinking…is no more and no less an organ of perception than the eye or ear. Just as the eye perceives colours and the ear sounds, so thinking perceives ideas.
— Rudolf Steiner

Although it is the brain rather than the sensory organs that perceives colors and sounds, it is true that conception is essentially a form of perception. While perception involves processing sensory information, conception involves processing abstract information. While our eyes and ears enable us to identify and physically manipulate sensations in the world, words enable us to identify and mentally manipulate relationships in the world.
