Display Excerpts of Posts in Wordpress Blog - wordpress

Question

I have been searching for the answer to my problem and I continually come up with replacing
<?php the_content(); ?>
with
<?php the_excerpt(); ?>
in the index.php file. However, the theme we are using does not contain this line. Anyone have any insight? Here is the code in our index.php file:
<?php $t =& peTheme(); ?>
<?php $content =& $t->content; ?>
<?php $meta =& $content->meta(); ?>
<?php get_header(); ?>
<section class="section-blog section-index" id="<?php $content->slug(); ?>">
<div class="row">
<div class="large-12 columns text-center">
</div>
</div>
<div class="row blog-main">
<div class="large-9 columns blog-left">
<?php $t->content->loop(); ?>
</div>
<?php get_sidebar(); ?>
</div>
</section>
<?php get_footer(); ?>
