"All right, young Po, teach me about this theoretical cell [174."
"It is like this Master. Because we have agreed that it is alive, it is active, therefore it uses energy or at least chemicals. So, internally there must occur a depletion or a lacune of something. On the other hand it is the cell's 'Outside' where a re-pletion may be found."
"Perfect Po. But we can design a machine that keeps a box of marbles filled to a certain level, automatically. I do not seem to understand fully?"
"Because you interupted me Master. I was going to explain that these depletions must 'hurt' the cell, and repletion must be pleasant. This, of course means 'emotion', and in its turn it means an 'Ego' that can have these emotive states. The dimension of an idea, therefore, is first of all an Ego-part, then an emotional colouring, and, of course, a Reality measurement."
"Excellent. I understand. Just forgive me my interuption, I
wanted to play the ignorant pupil." [174]
