  Does inflation provide a compelling explanation for why the universe is so
large, so flat, and so old, and a predictive theory of density perturbations?
In this brief contribution (based on the role of the author as moderator of the
discussion session on inflation), a list of some of the key issues confronting
inflationary cosmology will be given, with the hope of focusing the debate on
inflation and drawing more attention to some of the potential problems of the
inflationary theory.
