I believe Robert Frost stated it quite nicely in his popular and well know poem:
Fire and Ice
Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
With of course fire and ice being represented (and bluntly stated as) desire (close enough to love for government work) and hate.
Personally, I find myself persuaded by
>>3. They seem roughly equal, not from some mystical cosmic balance, but simply equilibrium.
