For this is the truth about our soul, he thought, who fish-like inhabits deep seas and plies among obscurities threading her way between the boles of giant weeds, over sun-flickered spaces and on and on into gloom, cold, deep, inscrutable; suddenly she shoots to the surface and sports on the wind-wrinkled waves; that is, has a positive need to brush, scrape, kindle herself, gossiping.
Also our fellow competitors, who are indeed the people just mentioned - we do not compete with men who lived a hundred centuries ago, or those yet not born, or the dead, or those who dwell near the Pillars of Hercules, or those whom, in our opinion or that of others, we take to be far below us or far above us. So too we compete with those who follow the same ends as ourselves; we compete with our rivals in sport or in love, and generally with those who are after the same things; and it is therefore these whom we are bound to envy beyond all others. Hence the saying.
The power of the human will to compete and the drive to excel beyond the body's normal capabilities is most beautifully demonstrated in the arena of sport.
It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions. Heaven is by favor; if it were by merit your dog would go in and you would stay out. Of all the creatures ever made he (man) is the most detestable. Of the entire brood, he is the only one...that possesses malice. He is the only creature that inflicts pain for sport, knowing it to be pain. The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creature that cannot.
But every fool describes, in these bright days, His wondrous journey to some foreign court, And spawns his quarto, and demands your praise,-- Death to his publisher, to him 'tis sport.
We seem to be riding on the top of the highest mast of the tallest ship; and yet at the same time we know that nothing of this sort matters; love is not proved thus, nor great achievements completed thus; so that we sport with the moment and preen our feathers in it lightly.
