阅读材料,回答问题。

材料一:商鞅说:“治世不一道,便国不法古。故汤武不循古而王,夏殷不易礼而亡。反古者不可非,而循礼者不足多。

材料二:北宋时苏轼给宋神宗的上书中说:“惟商鞅变法不顾人言,骤至富强,亦以召怨天下……虽得天下,旋踵灭亡。”(大意是:只有商鞅变法不顾人们的反对,虽然使得秦国骤然富强,但也使得天下人怨恨……后来虽然统一全国,但很快就灭亡了。)

材料三:(商鞅)集小(都)乡邑聚为县,置令、丞,凡三十一县。为田开阡陌封疆,而赋税平。平斗桶权衡丈尺……居五年,秦人富强。(大意是:商鞅集中小乡镇为县,安排县令、县丞管理,共31个县。承认土地私有,按土地平均赋税。统一度量衡……五年后,秦国富强起来。)
