Abstract
This chapter investigates the fundamental question of whether embodiment is necessary for consciousness. By examining the diverse sensory systems of humans and pigeons, the text demonstrates how physiological "hardware," such as retinal cone cells, constrains the subjective experience of colour. The discussion further explores the link between physical form and perception through sleight-of-hand magic experiments. These studies reveal that an observer’s biomechanical capabilities – specifically the presence or absence of an opposable thumb – directly influence their susceptibility to visual illusions like the French drop. Through these biological case studies, the chapter elucidates how "rules of thumb" and sensorimotor feedback shape conscious interactions with the environment. Finally, the inquiry extends to the realm of artificial intelligence, questioning whether disembodied Large Language Models can achieve authentic qualia or if a physical, robotic body is required for conscious experience. Readers will gain a comprehensive understanding of how the body acts as a moderating factor in consciousness, offering critical insights into the future of both biological and non-biological intelligence.
