The above quote signifies that The TRUTH does not rely on numbers or majority, and also it tells us one must not simply judge the truth on the basis of majority. Many people as we see blindly imitate the others, this is wrong, one must always use his mind to judge rather than just do what ALL are doing.
                  
                "In order to search the Truth, it is necessary, once in one's life, to put everything in doubt so far as possible." 
                                                                               --- Descrates

 Rene Descartes, was a french mathematician who is known as the as the father of analytical geometry, the bridge between algebra and geometry, The Coordinate System is named after him. What Descrates is saying is in support of our argument here that one must not simply follow the crowd.

                      Now to Simply as well as finalize the topic, Lets see an example, we have a Faulty laptop, we take it to its care center and tell the technician there to fix it without opening it and taking out its parts, Is this Acceptable? Absolutely Not! it sound crazy. That's the same thing here without taking out our old thoughts to renew them or modify them we can never correct ourselves. This is the place where arrogance and pride step in, that's why its said that arrogant and egoistic people never learn its because they don't let don't let there inner selves open to other ideas.

                                I hope this post enlightens you, All and Any type of comments are welcome.

Thanking you,
