Everything boils down to two questions. What should I do to keep myself safe? What should I do to keep others safe?
What should I do to keep myself safe? This is not a new question. Every day we risk our lives. We drive to work, ride up elevators, and eat different foods. Although driving is very dangerous, it’s necessary. We must risk our lives to accomplish necessary tasks. Each decision must be weighed on the scales of intellect. Is the risk worth the reward? What really matters in life?
What should I do to keep others safe? Once again, this is not a new question. We are obligated not to harm others. This obligation is not legal, social or biological – it is moral. When others’ lives are on the line, we must be extra cautious. At the same time, there's a limit. I must hand money to the cashier even though I risk unknowingly infecting him. Each decision must be weighed on the scales of intellect.
What are these scales of intellect, and how do we acquire them? These scales are our humanity, and they can only be acquired by learning about and thinking through a comprehensive moral framework.
