Top lists are lecturing people on everything from “100 books to read”. Aren’t you just tired of being told what to do with your time?

Now you have a list to end all lists!

Take a look at the following two examples from the list of “101 things not to do”:

Swim with Dolphins(海豚)?

Swimming with dolphins is one of the world’s most profitable tourist activities. However, every dolphin will welcome having their busy, tiring day interrupted by tourists screaming pushing around them in the water. Worse yet, when dolphins get too near to the boats loaded tourists, they could get caught up in ropes and killed by propellers(螺旋桨).

Here’s a little secret. Dolphins look like smiling at you, but actually they’re just opening mouths.

Go to See the Mona Lisa?

There must be something about the mysterious(神秘的) smile. The 6 million people who the lady in the Louvre every year can’t all be wrong after all. But they can be quite annoying standing in front of you, holding up their cameras to prevent you from seeing anything. In fact it is hard for you to see the painting clearly because you have to stay away from it for security read. After queuing for hours, many tourists can remain in front of the painting only for 15 seconds most.

If the mysterious lady in the picture knew her fate, she wouldn’t just be smiling, she laughing.

So, still long to see the Mona Lisa? If you want to find out more about the list, read 101 Things NOT to Do Before You Die. Visit www.not2dobeforeidie.co.uk and buy the book at a 20% discount.

“思想文化的发展是社会进步的重要推动力，同时也是社会发展的必然结果。”阅读下列材料并回答问题。

材料一

伏尔泰信奉自然权利说，认为“人们本质上是平等的”，要求人人享有“自然权利”。他主张人人在法律面前平等，但又认为财产权利的不平等是不可避免的。他认为：自然法就是符合人性或人的本能的、适用于所有人，并天下人都认为公正的自然法律。认识到“君主使人感到枷锁的分量”，主张以法治国，反对君主专断，断言人只有在自己的人格与自由得到尊重与保障的前提下，才能发挥自己的理性，推动社会繁荣。伏尔泰尖刻地抨击天主教会的黑暗统治。他把教皇比作“两足禽兽”，把教士称作“文明恶棍”，说天主教是“一些狡猾的人布置的一个最可耻的骗人罗网”。——百度百科

材料二

伏尔泰不遗余力地揭露和批判了宗教的虚伪、教士的凶残贪婪以及信徒的宗教狂热和不宽容造成的荒诞悲剧。“宗教狂热使科学本身也变成了它的同谋者，并扼杀理性”。伏尔泰自述：“我跑了很多不幸的弯路，疲惫因顿，……我又回到洛克这里来了，就像一个浪子回到他父亲那里一样。”伏尔泰反对不可知论，对理性怀有信心，他说：“我们不应当因为人类不能认识一切，就阻止人类去寻求于自己有用的东西。”——伏尔泰《哲学通信》

材料三

孔教与共和乃绝对两不相容之物，存其一必废其一，此义愚屡言之，张、康亦知之，故其提倡孔教必掊共和，，亦犹愚之信仰共和必排孔教。盖以孔子之道治国家，非立君不足以言治。——陈独秀《复辟与尊孔》

材料四

孔子生长封建时代，所提倡之道德，封建时代之道德也；所垂示之礼教，即生活状态，封建时代之孔教，封建时代之生活状态也；所主张之政治，封建时代之政治也。封建时代之道德、礼教、生活状态、政治，所心营目注，其范围不越少数君主贵族之权利与名誉，于多数国民之幸福无与焉。何以明之？儒家之言：社会道德与生活，莫大于礼；古代政治，莫重于刑。

——陈独秀《孔子与现代生活》

依据材料三、四并结合所学，简析陈独秀由此拉开的这场思想运动的历史价值。
