Alex Trebek’s voice had just trailed off after reading an answer associated with the life is absurd point of view of Albert Camus. Nobody rang in with the question “What is suicide” which is a natural conclusion if one shares the Sisyphean point of view of the famous French novelist.
According to Camus, “There is only one really serious philosophical question, and that is blank” to put it in the form of a jeopardy answer. None of the high IQ jeopardy contestants were able to fill in the blank.
Perhaps they were startled by such a melancholy interruption on the famous TV game show that has entertained and intellectually stimulated so many viewers over the years.
Also, if Albert Camus, whose life ended way too early in a car crash, really believes suicide is the only serious philosophical question, then one would have to conclude he held the rest of philosophy in very low regards!
