Logic, logic, logic..

 "Si así fue, así pudo ser; si así fuera, así podría ser; pero como no es, no es. Eso es lógica."

Lewis Carroll

Edit:

  Logic {sust.}

  It is clearly the logic of the nations.
  But that is not the logic of politics.

  To my mind that logic is unacceptable.

  We reject the logic of inevitable war.

  This is elementary economic logic.

  The logic is, indeed, very simple.

  It is a proposal based on logic.

  Let us follow through on that logic.

  The logic of force is persisting after the war.

  This is not policy; it is life's simple logic.
