Skepticism

Skepticism: A doubting or questioning attitude or state of mind; dubiety. 

"Believe nothing no matter where you read it or who has said it, not even if i have said it, unless it agrees with your own reason and your own common sense." Buddha

"Don't blindly believe what I say. Don't believe me because others convince you of my words. Don't believe anything you see, read, or hear from others, whether of authority, religious teachers or texts. Don't rely on logic alone, nor speculation. Don't infer or be deceived by appearances. Find out for yourself what is true and virtuous." Buddha

“Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.” Buddha
