这样大家就知道，经济学其实是一门很年轻的学科，跟美国的年龄一样大，才两百多三百年不到。这对于一门学科来说，可是很短的时间。正因如此，这门学科还有很多不完善的地方，充满了错误是理所当然的。大家今天都觉得物理学之类的自然科学基本上是没有错误的，但大家可别忘了，物理学是在几千年前的亚里斯多德就已经开始研究了。可是直到近代之前，物理学都发展了几千年啦，但大家看看，当时的物理学里是充满着多么多、又是多么厉害的错误！物理学家错误地认为，物体下降的速度是跟物体的质量有关。今天我们知道，这完全是错的。物体下降的速度跟物体的质量毫无关系，从表象看起来石头比羽毛下降得快，只是因为它受到空气摩擦力比较小而已。还有天文学，错误的地心说统治了多长时间了？相比之下，才发展了三百年不到的经济学，教科书里充满了错误又有什么值得大惊小怪的呢？只因为是写进了教科书里就不假思索地认定是没错的东西，那才值得惊奇哩！事实上，就连这本教科书的作者，其实他自己也并不一定是完全认为他写进这教材里的东西都是对的，只是写教科书不是写学术著作，要讲究随大流。目前来说学界一般认为是什么，他就得按着那个多数人的想法来写。可是，有一句话大家大概都很熟悉的，那就是：真理是掌握在少数人的手上的！
 
总之，经济学的教科书目前都充满了错误，我已经是选择错误最少的一本来给大家讲授。在讲课过程中，我会选择里面正确的内容来讲，但会不断地批判、纠正其中我认为是错误的地方，还会不断地补充我认为是正确的东西，
