"The flowers have been growing thorns for millions of years. For millions of years the sheep have been eating them just the same. And is it not a matter of consequence to try to understand why the flowers go to so much trouble to grow thorns which are never of any use to them? Is the warfare between the sheep and the flowers not important? Is this not of more consequence than a fat red-faced gentleman's sums? And if I know--I, myself--one flower which is unique in the world, which grows nowhere but on my planet, but which one little sheep can destroy in a single bite some morning, without even noticing what he is doing--Oh! You think that is not important!"
Antoine de Saint Exupéry. The Little Prince.
