If anything is possible, then one of those 'anythings'
is the event that 'not anything is possible'.
So the argument negates itself,
and thus is wrong according to its own premises.
The point being that to debate anything at all,
one is assuming that it is possible to reach
logical conclusions as a consequence of analysis.
So the base assumption proves that only logical
events can occur. Unless of course we refuse
to separate mind from body. In the mind, we can
claim that circles are actually squares.
But in the physical world we will not be able
to do this, which proves that the mind has
an essence which is a-logical: creativity.
Once more we see evidence that the mind is not a
property of the physical world.
