阅读下面短文,回答文后问题。
何谓文化向来狭义的解释,只指学术技艺而言,其为不当,自无待论。说得广的,又把一切人为的事都包括于文化之中,然则动物何以没有文化呢须知文化正是人之所以异于他动物的。其异点安在呢凡动物,多能对外界的刺激而起反应,亦多能与外界相调适。然其与外界相调适,大抵出于本能,其力量极有限,而且永远不过如此。人则不然。所以人所处的世界,与动物所处的世界,大不相同。人之所以能如此,(一)由其有特异的脑筋,能想出种种法子。(二)其手和足的作用分开,能制造种种工具,以遂行其计划。(三)又有语言以互相交通,而其扩大的即为文字。此人之所知,所能,可以传之于彼;前人之所知,所能,并可以传之于后。因而人的工作,不是个个从头做起的,乃是互相接续着做的。不像赛跑的人,从同一地点出发,却像驿站上的驿夫,一个个连接着,向目的地进行。其所走的路线自然长,而后人所达到的,自非前人所能知了。然则文化,是因人有特异的禀赋,良好的交通工具而成就的控制环境的共业。动物也有进化,但他的进化,除非改变其机体,以求与外界相适应,这是要靠遗传上变异淘汰等作用,才能达到目的的,自然非常迟慢。人则只须改变其所用的工具,和其对付事物的方法。我们身体的构造,绝无以异于野蛮人,而其控制环境的成绩却大不相同,即由其一为生物进化,一为文化进化之故。人类学上,证明白冰期以后,人的体质,无大变化。埃及的尸体解剖,亦证明其身体构造,与现今的人相同。可见人类的进化,全是文化进化。恒人每以文化状况,与民族能力,并为一谈,实在是一个重大的错误。遗传学家,论社会的进化,过于重视个体的先天能力,也不免为此等俗见所累。至于有意夸张种族能力的,那更不啻自承其所谓进化,将返于生物进化了。从理论上说,人的行为,也有许多来自机体,和动物无以异的,然亦无不披上文化的色采。如饮食男女之事,即其最显明之例。所以在理论上,虽不能将人类一切行为,都称为文化行为,在事实上,则人类一切行为,几无不与文化有关系。可见文化范围的广大。能了解文化,自然就能了解社会了。人类的行为,源于机体的,只是能力。其如何发挥此能力,则全因文化而定其形成。
