On the Shortness of Life is the most widespread work and one of the most important treaties of the great philosopher, playwright, politician and writer of the early Christian era, Seneca (4ac - 65dC), besides being one of the most popular texts of all Antiquity Latin. A man whose death exemplified selflessness and peace of mind he so preached, to find that "every one rushes to life, suffering from anxiety and boredom of the future of this." Astute observer of the political scene since that time he asked: "How many would prefer to see the Republic in disarray and not your hair?" Hence its key finding of the policy, and that also applies to today, that "a people hungry is not rational, therefore, no equity would know to calm him down, or fold it the prayers." Themes are developed as learning, friendship, books and death, and in the course of the pages will be shown ways to prolong life and rid her of a thousand trifles that no trouble, however, enrich it. His vision of proportionality and the difference between all things can be summed up in a beautiful phrase of his own: "Slow donkeys are better able to work that noble horses, and those who have oppressed them generous flexibility with a heavy bag?"
