Quote of the Day: Genesis Rabbah 1.5

I'm reading some Genesis Rabbah, a Palestinian midrashic collection, this evening, and the following line stuck out for me:

דא"ר יוסי בר חנינא כל המתכבד בקלון חבירו אין לו חלק לעולם הבא

Rabbi Yose son of Hanina said, "Whoever elevates himself by his fellow's degradation has no part in the world to come." (Genesis Rabbah 1.5)
