Ira brought up his concept at our recent Philo Club meeting, which he claims he shares with Einstein and Spinoza, that the sum of many consciousnesses is another super consciousness. He uses the fact that the sum of a multitude of neurons constituting the entire brain add up to a consciousness as a proof by analogy.
The trouble with this approach is that it produces the "Problem of the Heap." If there is a heap of grains and one grain is subtracted, does one still have a heap? If the answer is yes, and one keeps subtracting grains, at what point does one cease to have a heap? If one assumes there is a super consciousness, and one subtracts individuals, at what point does the super consciousness disappear? Both problems are born in the concept of vagueness. A heap is a vague concept and so is consciousness.
