So man in vain futilities toils on
Forever and wastes in idle cares his years-
Because, of very truth, he hath not learnt
What the true end of getting is, nor yet
At all how far true pleasure may increase.
And ’tis desire for better and for more
Hath carried by degrees mortality
Out onward to the deep, and roused up
From the far bottom mighty waves of war.
Lucretius, De Rerum Natura, Book V.1427-1435
