It is now more than a week since I've finished Galileo's Dream, and I am still contemplating the wisdom of this passage:
We all have seven secret lives. The life of excretion; the world of inappropriate sexual fantasies; our real hopes; our terror of death; our experience of shame; the world of pain; and our dreams. No one else ever knows these lives. Consciousness is solitary. Each person lives in that bubble universe that rests under the skull, alone.
Kim Stanley Robinson, Galileo´s Dream, 2009, p. 307
