ABSTRACT
A moral extremist hollows out a spectrum of options. An extreme extremist leaves a single ‘choice’. The most extreme extremist is the logical fatalist. He maintains there is exactly one possible world. There are no alternatives to what actually happens. The Stoics concluded there is no room for regret, anger, or fear of death. After the Stoics, fatalists continued to deduce other extreme consequences. But fatalists have yet to be extreme enough. To drive fatalism to its logical conclusion for ethics, I show how ‘There is only possible world’ triggers deontic logic into delivering a consistent and complete morality. Despite the absence of any moral premise, fatalism manages to be the most demanding morality. It is also the most practical of moralities. For fatalism ensures that you will meet all your obligations.
