在关于内因和外因问题的讨论中,冯增信同志写出《外因和内因》一文 (见《新华月报》1980年第8期转载自《复旦学报》1980年第3期),明确提出他的观点是:“在外因相对不变的情况下,事物的变化由内因决定,在内因相对不变的情况下,事物的变化由外因决定。”我认为这种观点值得商榷。 为了证明其观点,冯文举例说:“两个同卵双生子,如果一个从小由狼衔走,在狼窝中由母狼抚养大,从不接触人类社会,那末他就丝毫不具有人的智力,没有语言思维能力,只能用四肢爬行,象狼一样地嚎叫,争食;而他的兄弟,在精心培育下,则可能成为一个聪明伶俐的的孩子,长大后或许是著名的科学家。在这里,决 In the discussion on internal and external causes, Comrade Feng Zengxin wrote the article “External Causes and Internal Causes” (see Xinhua Monthly, 1980, No. 8, reproduced from Fudan Journal, 1980, No. 3), and clearly put forward his point of view Is: “In the case of relative invariance of external factors, the change of things is determined by internal factors, and when the internal factors are relatively unchanged, the changes of things are determined by external factors.” I think this view is open to question. In order to prove its point of view, Feng Wen said: "If the two identical twins, if one was from the wolf away in the wolf’s nest raised by the mother wolf, never contact with human society, then he did not have the human Intelligence, no language ability to think, can only crawl with limbs, howling like wolves, fighting for food; and his brother, carefully nurtured, may become a clever child, grow up may be famous Scientist.
