172Important truths begin as outrageous, or at least uncomfortable, attacks upon the accepted wisdom of the time.

------------------------------

172 同意

1. 真理通常是纠正以前错误的观点，人们已经习惯旧观点，难以接受新的正确的观点

For example, in 16th century, most people believed Aristotles theory that the objects falling speed is in proportion to its weight, whereas Italy scientist Galileo found the falling speed only related to the gravity and falling time. Of course, people did not accept the crazy thought in that time.However, the famous Pisa Tower experiment proved the truth.

2. 接受真理往往会影响或者削弱当前的一些人的地位和利益，所以他们会保护旧观点

In 16th century, Christianity supported geocentricism, however, Copernicus put forward contrary theory --- heliocentricism, which was regarded as heresy by Christianities because it did not accord with the Bible.

3. 真理有时是开辟人们认知的新领域，也难以接受
