Discuss Quentin Compson's internal and external conflicts in The Sound and the Fury.

As with so much in Faulkner, nothing is easy or simple. 
There are challenges all the way through with everything and everyone.  Consider the
warning on the watch that haunts Quentin, to a great
extent:

I give
you the mausoleum of all hope and
desire.

It is in this
statement where one can see both external and internal conflicts.  There is a desire to
want to overcome the external challenges that limit his own sense of self, but there is
also the internal that wages battle within Quentin's own mind and soul.  This makes his
life extremely difficult, where suicide becomes reality, and one that makes the
discernment between internal and external challenging.  I think that similar to how the
narration in the second section flips between real and fantasy, one has to concede that
the conflicts that present themselves also move between internal and external.  For
example, the feelings towards Caddy would be something that operates on both levels.  On
one hand, there is the act itself which is socially inappropriate, causing the external
conflict of Quentin versus society.  At the same time, there are the conflicted feelings
in which Quentin recognizes his own torn feelings towards the situation.  There is a
feeling of love and tenderness towards Caddy as well as uncontrolled hatred and
violence.  It is here where there can be conflict seen in terms of representing internal
and external, something that defines and haunts Quentins' character.  In the end, I
think you can identify the conflicts present and then make a case for them being
internal and external, representing qualities of both.
