内容简介：
"Thomas' mind was full of ideas, and he used the awe and beauty of nature around him as inspiration, as a way to build on and further master problems some of which he had thought of years before; some of which he had no answer to." On sabbatical from his teaching career at the university, Thomas, a professor of mathematics, searches for answers to the greatest modern and ancient problems vexing humanity. Calling upon the ideals laid forth by the great idealist thinkers of the past, he analyzes these dilemmas, as well as himself, and continually asks himself the question, "What is truly my purpose as an infinitesimal being residing in an infinitely large universe?" Without a unifying societal goal to guide him, our modern hero becomes lost in his thoughts only to find he must ultimately define himself, as well as his own personal purpose. In relinquishing his inner turmoil, he finally decides he must champion the cause for solving the "sustainability problem," one of the most pressing issues of modern civilization-can humans sustain themselves on Earth? Having found a purpose, Thomas exhibits newfound energy in attempting to bring the word to the public-at-large. But will tragedy destroy him in the end?
