这句话的意思是“古代的君子，他要求自己严格而全面，对待他人宽容而简约。”
古之君子，其责己也重以周，其待人也轻以约。重以周，故不怠；轻以约，故人乐为善。闻古之人有舜者，其为人也，仁义人也。求其所以为舜者，责于己曰：“彼，人也；予，人也。彼能是，而我乃不能是！”早夜以思，去其不如舜者，就其如舜者。闻古之人有周公者，其为人也，多才与艺人也。求其所以为周公者，责于己曰：“彼，人也；予，人也。彼能是，而我乃不能是！”早夜以思，去其不如周公者，就其如周公者。舜，大圣人也，后世无及焉；周公，大圣人也，后世无及焉。是人也，乃曰：“不如舜，不如周公，吾之病也。”是不亦责于身者重以周乎！其于人也，曰：“彼人也，能有是，是足为良人矣；能善是，是足为艺人矣。”取其一，不责其二；即其新，不究其旧：恐恐然惟惧其人之不得为善之利。一善易修也，一艺易能也，其于人也，乃曰：“能有是，是亦足矣。”曰：“能善是，是亦足矣。”不亦待于人者轻以约乎？问题补充：
