"The first precept was never to accept a thing as true until I knew it as such without a single doubt"

Rene Descartes' quote is a pointer to always question and think seriously. He is recommending that we must never ever take something as true up until we have actually analyzed it and are specific of its truth. This is an important principle in approach, as it motivates us to think for ourselves and not simply accept what we are informed. Descartes' quote motivates us to be open-minded and to question the credibility of any information we receive. It likewise motivates us to believe for ourselves and to come to our own conclusions. By doing this, we can guarantee that we are not being misinformed or tricked. Descartes' quote is a suggestion to constantly believe seriously and to never accept something as true up until we are certain of its truth.
