Why does the book feel warm to the touch?  it feels warm because its relative heat is warmer than that of my fingertips.  How is this possible?  How is heat possible within something that is not living?  it must have warmth within it because it feels warm to the touch.  This is just the strength of the suns rays reacting within and heating up its molecules.  How can this mean that it is warmer than I, who has the advantage of the suns rays as well as creating my own warmth?  It is due to relativity.  My fingers are a lot colder than my centre which creates the illusion that the book feels warmer.  What is illusion, does it not suggest the intervention of an outside (sentient) force, or is illusion just the wrong choice of word?  the wrong choice, quite simply.  equally, if i touch the stone by my side, it is considerably colder than my fingers, this suggests that the relativity between my centre and my extremities is not the only force acting upon the feeling of warmth from the book.  the book itself must be warmer than the stone, why, if there is no life inside the book?  well, there used to be life.  (a question that should have been asked at the start) Does the production of warmth equate to life?  no.  only mammals.  but equally it is within the interests of the life form to restrict the amount of heat loss that occurs because life does not exist without some warmth.  i think it is likely that there are residual effects of these devices available within the book[....]
