“Running toward danger is foolhardy. ... But so is closing your eyes to it. Many perils become less dangerous once you understand their potential hazards.”

“If a man is alive, there is always danger that he may die, though the danger must be allowed to be less in proportion as he is dead-and-alive to begin with. A man sits as many risks as he runs.”

“Information is strength without coordination. We become a danger mostly to ourselves when we have it. Understanding is the ability to coordinate that raw information in meaningful ways. Understanding creates a certain enthusiasm. We can direct our knowledge toward potentially useful ends--but we may also be a danger to others. Wisdom, however, is knowing how, when, and why we use our understanding; wisdom is settling into our understanding without being too enamored by it.”

“Of course, being brave does not mean running towards danger.”

“If you walked into your local convenience store and bought a package of cigars, you would notice that it carries a label warning of the potential dangers of cigar smoke. Yet research suggests that cigar smoking poses a hazard only to moderate to heavy cigar smokers, who comprise less than 1 percent of the adult population. More than 97 percent of American adults, however, eat animal foods, and despite much research demonstrating the connection between the consumption of animal products and disease, we are not warned of these dangers.”

“Obviously this person's a hazard. Stupid people are dangerous.”
