"It is so easy for human thinking to become distorted that it makes sense to examine how we can keep our own thinking straight and thus avoid calamity. Importantly, we need to be on guard against the trickery of men. Make no mistake, you will encounter deceitful people who pretend to present the truth but actually distort it. To attain their objectives such people may resort to a selective use of evidence, emotionally loaded language, misleading half-truths, devious innuendo, and even outright lies.|"
