"For an answer which cannot be expressed the question too
     cannot be expressed. / _The riddle_ does not exist. / If 
     a question can be put at all, then it _can_ also be 
     answered."


    "All propositions are of equal value. / The sense of the 
     world must lie outside the world. In the world everything
     is as it is and happens as it does happen. _In_ it there 
     is no value -- and if there were, it would be of no 
     value."


    "At the basis of the whole modern view of the world lies 
     the illusion that the so-called laws of nature are the
     explanations of natural phenomena. / So people start 
     short at natural laws as at something unassailable, as 
     did the ancients at God and Fate. / And they both are 
     right and wrong. But the ancients were clearer, in so far
     as they recognized one clear terminus, whereas the modern
     system makes it appear as though _everything_ were
     explained."


    "If by eternity is understood not endless temporal 
     duration but timelessness, then one lives eternally who
     lives in the present. / Our life is endless in the way 
     that our visual field is without limit. / The temporal
     immortality of the human soul, that is to say, its 
     eternal survival after death, is not only in no way
     guaranteed, but this assumption in the first place will
     not do for us what we always tried to make it do. Is a
     riddle solved by the fact that I survive forever? Is
     this eternal life not as enigmatic as our present one?"


    - Ludwig Wittgenstein (1889-1951), Tractatus 
      Logico-Philosophicus

  
   "Whenever we say that something must be the case we have given
    an indication of a rule for the regulation of our expression,
    as if one were to say 'Everybody is really going to Paris. 
    True, some don't get there, but all their movements are 
    preliminary'."

   "The use of money and the use of words are analogous. Money is 
    not always used to buy things which can be pointed to, e.g., 
    when it buys permission to sit in a theatre, or a title, or 
    one's life."

   "How can one know whether an action or event has the quality 
    of goodness? And can one know the action in all of its details
    and not know whether it is good? That is, is its being good 
    something that is independently experienced? Or does its 
    being good follow from the thing's properties?"

    -Ludwig Wittgenstein (1889-1951), Philosophical Investigations
