Quanta and Qualia
  I sketch a line of thought about consciousness and physics that gives some motivation for the hypothesis that conscious observers deviate - perhaps only very subtly and slightly - from quantum dynamics. Although it is hard to know just how much credence to give this line of thought, it does motivate a stronger and more comprehensive programme of quantum experiments involving quantum observers.
