What are the motifs in The Human Comedy by William Saroyan?

A recurring idea that manifests and develops the book's primary theme is the idea of home, a word loaded with all kinds of universal associations. While for many people these associations can be negative, with the concept of "home" carrying with it implications and/or memories of dysfunction and unhappiness, society in general and "The Human Comedy" in particular focuses on the more positive associations of safety, of love, and of support. It's not an exaggeration to say that these positive associations, much more than the negative ones, are mythic in their status, power, and personal relevance, reflections and manifestations of a recognized archetype, or expression of a universal human truth - that everyone longs to reach both the physical and spiritual place in which they feel secure, cherished, valued, and at peace.
