What is a quote that shows that Gene Forrester is intelligent and another that shows he is insecure in A Separate Peace?Please include page...

Gene Forrester's envy of Phineas is, of course, born of
insecurity, and his observations of Finny are redolent with this insecurity.  For
instance, in Chapter 2 when Finny wears a pullover roadcloth shirt in pink to class, and
not one of the instructors said anything about it during classes, Gene remarks in his
unsureness of himself:

I was beginning to see that Phineas could get
away with anything....because of the extraordinary kind of person he was.  It was quite
a compliment to me, as a matter of fact, to have such a person choose me for his best
friend.

As Finny recalls the
conversation he has had with Mr. Patch-Withers, Gene replies sarcastically, admitting to
his insecurity:

As I said, this ws my sarcastic summer.  It was
only long after tht I recognized sarcasm as the protest of people who are
weak.

In Chapter 3 Gene
further admits that

readability="6">

I was subject to the dictates of my mind, which
gave me the maneuverability of a
straitjacket.

Later, when
Finny breaks the school swimming record, he tells Gene that he just did this to see if
he could.  Gene narrates,

Perhaps for that reason his accomplishment took
root in my mind and grew rapidly in the darkness where I was forced to hide
it.

Then, in their room,
Finny tells Gene in his recognition of Gene's
intelligence,

readability="6">

You know all about History and English and French
and everything else.  What good will Trigonometry do
you?

But this discussion,
also, results with more insecurity upon Gene's part as he hears Finny talk of studying
and becoming "head of the class."  His eyes snap in envy from the textbook to
Finny: 

But
what did go on in his mind?  'If I was the head of the class and won that prize, then we
would be even...'

Now, Gene
becomes worried that Finny will try to surpass him intellectually, as well.  This
insecurity is reinforced by the incident in which he and Finny are in the library,
studying for a French examination, but Finny passes nonsensical notes and "I didn't get
any work done."  After Gene returns to his room, Finny enters, announcing that Leper has
decided to jump this night, so Gene must attend.  Gene, in his insecurity, suspects
ulterior motives on Finny's part:

Finny had put him [Leper] up to it, to finish me
for good on the exam.

When
Gene expresses this thought, Finny is surprised.  He tells Gene he is
intelligent:

readability="10">

Listen, I could study forever and I'd never
bread C.  But it's different for you, you're good. you rally are.  If I had a brain like
that, I'd--I'd have my head cut open so people could look at
it....

And, Gene becomes
ashamed of his insecurity:

readability="6">

He had never been jealous of me for a second. 
Now I knew that there never was and never could have been any rivalry between us.  I was
not of the same quality as he.
