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.
出自汉·桓宽《盐铁论·国疾》。谀言，阿谀奉承的话。这句话以林中必然多疾风为喻，说明富贵之后就有趋炎附势之徒进阿谀奉承之言的必然性。释义：森林中往往刮大风；富贵人面前往往都是一堆奉承话。
This world is the best of all possible worlds.
Deep into that darkness peering, long I stood there wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before.
