He who fears death will never do anything worthy of a living man. But he who knows that this was the condition laid down for him at the moment of his conception will live on those terms, and at the same time he will guarantee with a similar strength of mind that no events take him by surprise. For by foreseeing anything that can happen as though it will happen he will soften the onslaught of all his troubles, which present no surprises to those who are ready and waiting for them, but fall heavily on those who are careless in the expectation that all will be well.
