Upton Sinclair 
On Guard [EPUB ebook] 
"I intend to do what little one man can do to awaken the public conscience."

Upton Sinclair (1878-1968) was a prolific American novelist and a political activist. Apart from his bestselling novels, which told in black and white, illuminated the realities of the United States at the turn of the twentieth century, he is remembered today for championing socialist causes that were naturally unpopular in conservative America. In classics like ‘The Jungle’ his work had considerable effects on American politics and legislation. Sinclair’s socialist ideals and dreams found their way to his fiction as he believed that no art can be practiced for art’s sake as long as humanity still suffers from persistent dangers and evils. Such orientations have often subjected Sinclair to harsh criticism and even to demonization from numerous critics and politicians of his time, the most distinguished among which was probably President Theodore Roosevelt. However his legacy is that of a successful and established novelist and activist who if not always righting the balance was able to bring an incisive mind and mass exposure to many areas and industries.
