A prominent Cyrenaic named Hegesias, author of a book called *Death by Starvation*, lectured in Alexandria. He taught the doctrine of withdrawing from a malevolent world. The only way to avoid pain is suppress and/or rid oneself of desire. The goal of life is to pain avoidance—to the point that death is preferable to life.
He was highly effective: many of his readers and audience committed suicide.
Subsequently, Hegesias was banned from teaching in Alexandria.
