阅读下面的文字,完成下列小题。

    文化自觉是指生活在特定文化历史圈子里的人对其文化及其发展历程的充分认识,对其文化的来龙去脉要有自知之明。简言之,文化自觉实际就是文化的自我反思、自我觉醒的过程。文化自觉是一个艰巨的过程,只有在认识自己的文化,理解并接触到多种文化的基建上,才有条件在这个正在形成的多元文化的世界里确立自己的位置,然后经过自主的适应,和其他文化一起,取长补短,共同建立一个有共同认可的基本秩序和一套多种文化都能和平共处、各抒所长、连手发展的共处原则。”为此,他晚年曾将文化自觉的历程进一步精炼概括为十六字原则。

    在文化自觉、文化自信、文化自强的序列中,文化自觉是最具前提性的。从理论经上说,只有真正意义上的文化自学,才会有发自内心的文化自信,也才会有文化自强的底气。当然,我们今天谈文化自信、文化自强,首先必须要有置身于历史向世界历史转变的全球化进程中的真正的文化自觉。这种文化自觉对文化软实力在世界各国综合国力较量中的充分体认,要有对西强我弱的文化格局中文化安全的足够估计。在现实中,在从文化大国向文化强国迈进的历史进程中,我们必须深刻地认识到,只有基于文化自觉的文化自信才是接地气的,真正立得住的,叫得响的,基于文化自信的文化自强也才是有底气的,一个真正的文化强国才是可期待可达致的。

    较之道路自信、理论自信、制度自信,文化自信是最具根本性的。文化自信何以是“四个自信”中最具根本性的自信呢?这是由文化的来源、功能和地位所决定的。从文化的来源来看,文化即人化,文化无时无刻不深深地带有人类活动的印记;从文化的功能来看,文化即化人,《周易》有云:“观乎天文,以察时变;观乎人文,以化成天下”;从文化的地位来看,文化是民族的血脉,人民的精神家园。就此而论,一个没有文化的民族,其血脉是不通畅的,精神家园是坍塌的,没有文化浸润滋养的人民,精神是没有寄托之所、灵魂是没有栖息之地的。

    当“我宁愿坐在宝马里哭,也不愿坐在自行车后面笑”成为一些人的追求和目标的时候,当“老人摔倒,管还是不管”成为一个问题的时候,我们不禁会问,我们到底需要一种什么样的文化与价值?在现实中形形色色的文化错位、价值乱象的浮云面前,我们必须保持清醒的头脑,对文化的本性及其应有的地位心知肚明、了然于心,不畏浮云遮望眼。因此只有在“四个自信”的坐标中重新审视文化自信,我们才能真正把握其根本性之所在。
