An objection lurks here. Dworkin distinguishes between my circumstances, for which I am not reasonably held responsible, and my ambitions, for which I am reasonably held responsible, and includes native talent endowment among circumstances. But my native talent endowment may unfortunately leave me with poor value-forming and ambition-forming and choice-making ability, so that shortfalls in my condition that result from my acting on my ambitions may just express a shortfall in my native talent endowment. So according to Dworkin I both am and am not reasonably held responsible for my condition.
