"### 思维的乐趣 \n",

"### quotes from 《我的精神家园》\n",
"谈到思想的乐趣，我就想到我父亲的遭遇。我父亲是一位哲学教授，在五六十年代从事思维史的研究。在老年时，他告诉我自己一生的学术经历，就如一部恐怖电影。每当他企图立论时，总要在大一统的思想体系里找到自己的位置，就如一只老母鸡要在一个大搬家的宅院里找地方孵蛋一样。结果他虽然热爱科学而且很努力，在一生中却没有得到思维的乐趣，之收获了无数的恐慌。他一生的探索，只剩下了一些断壁残垣，收到一本名为《逻辑探索》的书里，在他身后出版。\n",
"\n",
"我在沉默中过了很多年：插队、当工人、当大学生，后来又在大学里任过教。当教师的人保持沉默似不可能，但我教的是技术性的课程，在讲台上只讲技术性的话，下了课我就走人。找我看，不管干什么都可以保持沉默。当然，我还有一个终身爱好，就是写小说。但是写好了不拿去发表，同样也保持了沉默。至于沉默的理由，很是简单。那就是信不过话语圈。从我短短的人生经历看，它是一座声名狼藉的疯人院。当时我怀疑的不是说过亩产三十万斤粮、炸过精神原子弹的那个话语圈，而是一切话语圈子。\n",
"\n",
"还有一些人，因为种种原因，对于话语的世界有某种厌恶之情。我属于这最后一种。作为最后一种人，也有义务谈自己的所见所闻。\n",
