Be a free thinker and don't accept everything you hear as truth. Be critical and evaluate what you believe in.
We do not know a truth without knowing its cause.
The least initial deviation from the truth is multiplied later a thousandfold.
The high-minded man must care more for the truth than for what people think.
The investigation of the truth is in one way hard, in another easy. An indication of this is found in the fact that no one is able to attain the truth adequately, while, on the other hand, no one fails entirely, but everyone says something true about the nature of all things, and while individually they contribute little or nothing to the truth, by the union of all a considerable amount is amassed.
