臺灣籍旅美老師今天交給我們的句子是：

Our instincts tell us that deliberately causing someone's death is different that allowing them to die as collateral damage. It just feels wrong for reasons that are hard to explain. This intersection between ethics and psychology is what's so interesting about the trolley problem. The dilemma in its many variations reveal that what we think is right or wrong depends on factors other than a logical weighing of the pros and cons.
我們的直覺告訴我們：“故意致人于死”與“放手不管而讓人死去使其成為附帶犧牲品”，這是不同的。這就是令人感覺不太對勁兒卻又難以解釋原因。道德學和心理學的交會處（人生的十字路口），就是電車難題為何如此有意思的地方。各式各樣的困境難題顯示，我們所認為的對錯判斷除了取決于邏輯上利弊權衡之外，還有其它因素。
