Marcus Aurelius was Roman Emperor from 161 to 180. He was the last of the Five Good Emperors, and is also considered one of the most important Stoic philosophers.<br /><br />While on campaign between 170 and 180, Aurelius wrote his Meditations in Greek as a source for his own guidance and self-improvement. The title of this work was added posthumously&mdash;originally he titled his work simply: &quot;To Myself&quot;. He had a logical mind and his notes were representative of Stoic philosophy and spirituality.<br /><br />Meditations is still revered as a literary monument to a government of service and duty. The book has been a favourite of Frederick the Great, John Stuart Mill, Matthew Arnold, Goethe, Wen Jiabao, and Bill Clinton.
