The dream of Galileo -- Evidence : experiments of nature -- Introduction : displacements -- Cerebrum : in which it is shown that the corticothalamic system generates consciousness -- Cerebellum : in which it is shown that the cerebellum, while having more neurons than the cerebrum, does not generate consciousness -- Two blind painters : in which it is shown that sensory inputs and pathways are not necessary for consciousness -- A brain locked in : in which it is shown that motor inputs and pathways are not necessary for consciousness, nor are they sufficient -- Empress without memory : in which it is shown that many brain circuits that help us see, hear, remember, speak, and act are not necessary for consciousness -- A brain split : in which it is shown that consciousness is divided if the brain is split -- A brain conflicted : in which it is shown that consciousness can split if different regions of the brain refuse to talk to each other -- A brain possessed : in which it is shown that when cortical neurons fire strongly and synchronously, as during certain seizures, consciousness fades -- A brain asleep : in which it is shown that when cortical neurons can be on and off only together, as during dreamless sleep, consciousness fades -- Theory : experiments of thought -- Introduction : the enigma of consciousness -- Galileo and the photodiode : in which it is shown that the humble photodiode can tell light from dark as well as Galileo -- Information : the manifold repertoire : in which it is shown that the repertoire of possible experiences is as large as one can imagine -- Galileo and the camera : in which it is shown that the sensor of a digital camera has a large repertoire of possible states, perhaps larger than Galileo's -- Integrated information : the many and the one : in which it is shown that consciousness lives where information is integrated by a single entity above and beyond its parts -- Galileo and the bat : in which it is shown that the quality of experience cannot be derived from matter -- Seeing dark (deconstructing darkness) : in which it is shown that darkness does not exist is a void but requires a context -- The meaning of ark (constructing darkness) : in which it is shown that darkness is built of many nested mechanisms that specify what it is not -- The Palace of Light : in which it is shown that an experience is a shape made of integrated information -- The Garden of Qualia : in which it is said that the universe is mostly dark, but the largest stars are closer than one thinks, if they are looked at with the proper instrument -- Implications : a universe of consciousness -- Introduction : sparks and flames -- Nightfall I : death : in which it is said that, if consciousness is integrated information, is dissolves with death -- Nightfall II : dementia : in which it is said that consciousness disintegrates with dementia -- Nightfall III : dolor : in which it is said that, if the quality of consciousness is a shape made of integrated information, it can be turned into the only real and eternal Hell -- Twilight I : consciousness diminished : in which it is said that consciousness can be present in the absence of language and reflection -- Twilight II : consciousness evolving : in which it is said that animals are conscious, too -- Twilight III : consciousness developing : in which it is said that consciousness must be present, to some degree, even before birth -- Daylight I : consciousness exploring : in which it is said that, by investigating nature, new qualia are discovered -- Daylight II : consciousness imagining : in which it is said that are and imagination invent new shapes within the mind -- Daylight III : consciousness growing : in which it is said that, by growing consciousness, the universe comes more into being, the synthesis of one and many -- Epilogue : three late dreams -- Afterthoughts : study questions.
