“Mere behaviour”. “There is only behaviour” would seem to say that there was no life that we (or I) acted as automatons, as unconscious mashines.
  I wish to say: “The difference between me & a mashine doesn't only just consist in the difference of our actions but in this that I am conscious & the mashine isn't”.
  But oughtn't I say that this only distinguishes a machine from me not from a human being? For why shouldn't I say that the difference between a human being, animal, sewing machine, etc., lies in their actions, if I except myself. But then I dont even except my body.
