To Err is Human; to Disagree, Jewish

"The defects of the world, both material and the spiritual, all derive from the fact that every individual sees the aspect of existence that pleases him, and all other aspects that are baffling to him seem to deserve purging from the world. This thought leaves its imprint on individuals and groups, on generations and epochs -- whatever is outside one’s own is destructive and disturbing." - Rav Kook, Orot HaKodesh 1:121
