阅读下列材料
材料一：
始皇推尊五德之传，以为周得火德，秦代周德，从所不胜。方今水德之始，改年始、朝贺皆自十月朔。衣服旄旌节旗皆尚黑。数以六为纪，符、法冠皆六寸，而舆六尺。六尺为步，乘六马。更名河为德水，以为水德之始。刚毅戾深，事皆决于法，刻削，毋仁恩和义。然后合五德之数。——《史记·秦始皇本纪》
材料二：
文选，吏部主之。……凡择人之法有四。一日身，体貌丰伟；二日言，言辞辩正；三日书，楷法遒美；四日判，文理优长。四事皆可取，则先德行，德均以才，才均以劳。得者为留，不得者为放。五品以上不试，上其名中书门下。六品以下始集而试，观其书、判；已试而铨，察其身、言；已铨而注，询其便利而拟。已注而唱，不厌者得反通其辞。三唱而不厌，听冬集。厌者为甲，上于(尚书)仆射，乃上门下省。给事中读之，黄门侍郎省之，侍中审之，然后以闻。……皆给以符，谓之告身。——《新唐书·选举志》
材料三：
宋朝设官之制，名号、品秩一切袭用唐旧。……三省、六曹、二十四司，互以他官典领，虽有正官，非别敕不治本司事。事之所寄，十亡二三。……官人授受之别，则有官、有职、有差遣。官以寓禄秩、叙位著，职以待文学之选，而差遣以治内外之事。其次又有阶，有勋，有爵。故士人以登台阁、升禁从为显宦，而不以官之迟速为荣滞；以差遣要剧为贵途，而不以阶、勋、爵、邑有无为轻重。——《文献通考·职官考》
材料四：
宣政院，秩从一品，掌释教僧徒及吐蕃之境而隶治之。遇吐蕃有事，则为分院往镇，亦别有印。如大征伐，则会枢府议。
其用人则自为选，其为选则军民通摄，僧俗并用。至元初，立总制院，而领以国师。二十五年，因唐制吐蕃来朝见于宣政殿之故，更名宣政院。——《元史·百官志》
材料五：
自有史以来，以元代为最无制度，马上得之，马上治之。当其清明之日，亦有勤政爱民，亦有容纳士大夫一二见道之语，然于长治久安之法度，了无措意之处。——孟森
蒙古恃其武力之优越，……其来中国，特惊羡其民物财赋之殷阜，而并不重视其文治。……他们欠缺了一种合理的政治理想，他们并不知所谓政治的责任，因此亦无所谓政治的事业。他们的政治，举要言之只有两项，一是防治反动，二是征敛赋税。——钱穆
