The sea is not less beautiful in our eyes because we know that sometimes ships are wrecked by it. On the contrary, this adds to its beauty. If it altered the movement of its waves to spare a boat, it would be a creature gifted with discernment and choice and not this fluid, perfectly obedient to every external pressure. It is this perfect obedience that constitutes the sea's beauty.
All the horrors produced in this world are like the folds imposed upon the waves by gravity. That is why they contain an element of beauty. Sometimes a poem, such as The Iliad, brings this beauty to light.
