We might also discover, perhaps to our amazement, that our practice of Stoicism has made us susceptible to little outbursts of joy: We will, out of the blue, feel delighted to be the person we are, living the life we are living, in the universe we happen to inhabit. For the ultimate proof that we have made progress as Stoics, though, we will have to wait until we are faced with death. It is only then, says Seneca, that we will know whether our Stoicism has been genuine.
