Death is neither a good nor a bad thing, for that alone which is something can be a good or a bad thing: but that which is nothing, and reduces all things to nothing, does not hand us over to either fortune, because good and bad require some material to work upon. Fortune cannot take ahold of that which Nature has let go, nor can a man be unhappy if he is nothing.
