The concept of proof depends upon the concepts of cause and effect, among
other things.  Even the ideas "anything" and "functioning" depend upon
the idea of cause and effect.  All of these concepts depend on or are
rooted in the concepts of identity and identification.  Here's why:

To be is to be something in particular, to have a specific identity, or
having specific characteristics.  What does it mean to have specific
characteristics or a specific identity?  It means that in a particular
context, the entity's existence is manifested in a particular way.  An
entity IS what it can DO (in a given context).

So what's causality?  The law of identity applied to action.  Things do
what they do, in any given context, BECAUSE they are what they are.
"What they are" includes or consists of "what they can do".
This is true irrespective of our ability to identify what they are.

Hume's and Kant's arguements re causality are the analytic-synthetic
dichotomy.  For the original presentation of the views that smash
this false dichotomy, see Leonard Peikoff's article "The Analytic-
Synthetic Dichotomy" in the back of recent editions of Ayn Rand's
"Introduction to Objectivist Epistemology".  For the epistemological
basis of Peikoff's article, read Rand's Intro.

This is simply not true.  The notion of logical proof involves implication
relationships between discrete statements in discourse.  This is an agreed 
upon rule of the game.  Causality assumes implication relationships between 
discrete events in the world.  The universe may or may not argue like a
philosopher, and it is not always clear what constitutes a "discrete" event.

This is a denial of causality, not a definition.  If things do what they
do because they are what they are, then they certainly can't be *caused*
to do anything by something else.  

Unless, of course, the only *thing* is everything.

	A short news item came to mind when reading a recent letter
on 'cause and effect'.

	It has very little to do with even less, but I found it very
amusing:



	A current production of Shakespear's Hamlet in Tokyo has the
imortal line 'To be, or not to be - that is the question.' translated
into Japanese with the following meaning;

		"It is,or is it? Isn't it?  (!)

My question:

	Is it unreasonable to presume a "prime spontaneous event"?  Doesn't
quantum mechanics allow for "spontaneous" movements at the particle level?
(Spontaneous here meaning that the particle is found to be in a very 
improbable location.)  Can these spontaneous particle translations not have
an impact on other particles, resulting in an amplified result, eventually
changing something at the macroscopic level?

My second question:

	Just how incorrect is my interpretation of quantum mechanics?
