Abstract
Fanaticism is the view that, for every finite good x and every positive probability p, there is a finite good y such that getting y with probability p is better than getting x for sure. I develop a neglected argument for a form of fanaticism limited to life saving scenarios. I explain how my argument is compatible with some forms of small-probability discounting, imprecise probabilism, risk-aversion and aggregation scepticism. I also try to respond to theoretical problems that fanatical arguments encounter in cases that involve infinitely many possible people. I also suggest why, even if fanaticism is true, we might often be warranted in our intuitive reluctance to accept fanatical conclusions.
