the existentialist of hard choices Maybe Sophie, in choosing between which of Jan and Eva to save from the Nazi gas chambers, was forced to do something that was not guided by reasons. When she chose to save Jan, she was not acting within the scope of her rational agency because practical reason had broken down – she had to existentially plump rather than rationally choose. Hard choices of the second variety allow responses within the scope of rational agency — you remain a rational agent as you agonize over what to do just as you remain a mathematician as you painstakingly work out the next line of the proof. In these substantively hard cases, it makes sense to continue to deliberate, agonize, ask your mother for advice, and so on. When we choose in such cases, we are exercising our rational agency, not simply plumping like Sartrean existential agents.Continuing the End Times series, Richard Marshall interviews Ruth Chang.
