A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
Stefan Banach

Divine life is in touch with the whole universe on the analogy of the soul's contact with the body.
Muhammad Iqbal

Kids are a great analogy. You want your kids to grow up, and you don't want your kids to grow up. You want your kids to become independent of you, but it's also a parent's worst nightmare: That they won't need you. It's like the real tragedy of parenting.
Jonathan Safran Foer

Ian Anderson
