Ancient Greek philosophers, describing and commenting on the uncontrolled anger, particularly toward slaves, in their society generally showed a hostile attitude towards anger. Galen and Seneca regarded anger as a kind of madness. They all rejected the spontaneous, uncontrolled fits of anger and agreed on both the possibility and value of controlling anger. There were however disagreements regarding the value of anger. For Seneca, anger was "worthless even for war". Seneca believed that the disciplined Roman army was regularly able to beat the Germans, who were known for their fury. He argued that "...in sporting contests, it is a mistake to become angry".
