1. The high-minded man must care more for the truth than for what people think.
2. For though we love both the truth and our friends, piety requires us to honor the truth first.
3. The least deviation from truth will be multiplied later.
4. With the truth, all given facts harmonize; but with what is false, the truth soon hits a wrong note.
5. 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.
