I've just re-read my first post, and see that I didn't make my meaning clear: "All those lost in the sea" meant the Titanic victims, and "mankind's hubris" refers to believing that this marvellous ship was so perfect and unsinkable that they could ignore basic safety precautions and warnings, and withstand a gigantic force of nature.

And they say there's naught can sink her, not even God's own hand
Man's pride can be his own downfall . . .
