Now (obviously) a sentence’s truth—even when we hold the sentence’s meaning fixed—depends on which world we are considering. “Brown is Prime Minister” is true in the actual world but, since Brown need not have been Prime Minister, there are countless worlds in which “Brown is Prime Minister” is false: in those worlds, Brown did not succeed Tony Blair, or never went into politics, or never even existed. And in some other worlds, someone else is Prime Minister — David Cameron, P. F. Strawson, me, Madonna, or Daffy Duck. In still others, there is no such office as Prime Minister, or not even a Britain; and so on and so forth. So a given sentence or proposition varies its truth-value from world to world.
Intuition goes before you, showing you the way. Emotion follows behind, to let you know when you go astray. Listen to your inner voice. It is the calling of your spiritual GPS system seeking to keep you on track towards your true destiny.
Some people are highly empathic, some people are telempathic, or telepathic, some are clairempathic, while others are claircognizant, clairvoyant, clairaliant, clairaudient, clairgustant, clairsentient; and a very few are all of the above. The great amount of confusion and inner strife that accompanies one or more of these conditions, can be calmed and soothed first by acceptance, second by the humility to be okay with the fact that you are stuck with it forever, and third by honing these conditions to their best possible uses and most polished states.
