Les Miserables - Victor Hugo

"Get it well fixed in your noodles, my children, that you are in the true road. Love each other. Be foolish about it. Love is the folly of men and the wit of God. Adore each other."

 

Oh, and this one too...

 

"Science, after having long groped about, now knows that he most fecundating and the most efficacious of fertilizers is human manure. There is no guano comparable in fertility with the detritus of a capital. A great city is the most mighty of dung-makers. If our gold is manure, our manure, on the other hand, is gold."

 

Awesome. Now we know.
