20:20 in this section Mr. Fry brought us to a question of ethics through the statement, "never stop being a child who asks why." I thought this was a beautiful way to remind us of what sets the achievers away from the average. The one who has a question and a passion for explanation is the one who will set out to discover. In their journey they will change their life and the lives of others through their exploration for "why." The other point he makes in this section touches on the use of words in defining legal and ethical boundaries. Why someone might consider an embryo a mass of cells one day and a baby the next. I think that amounts and boundaries are not quantitative and more flexible and change according to personal belief, and so, everyone should have their own choice, it shouldn't be forced on them. But at what point are boundaries necessary? There are laws for a reason and they shouldn't be stretched too thin. At what point is killing lawful? at what point is a pile of beans a heap? A simple metaphor ties into a much deeper meaning.
