Most are aware of The Trolley Problem. It's one of those so-called "thought experiments" academics have contrived, presumably to make us, or at least their poor students, think. It was apparently created by an English philosopher named Philippa Foot.
A railroad or trolly track splits into two tracks going in separate directions. By throwing a switch you may cause the trolley to take either route. Throwing it one way (A) will cause the trolley to follow the track to which five people are tied, killing them. Throwing it the other way (B) will cause the trolley to follow the other track to which a single person is tied, killing that person. Which way should you throw the switch?
There are variants of the problem. What if the person tied to track B is a child? Would your choice be different? What if a mass murder is tied to B? What if it is Jeffrey Dahmer, munching on the leg of one of his victims?
Food for thought, no doubt (sorry). How should you decide?
Well, like all of philosophers' problems, there is no definite answer. Therein I think lies The Trolley Problem's problem. It's the same problem other philosophical problems possess.
It's not an actual problem. That is to say, it's not a problem which would arise, in life. Why are we being asked to solve a problem which will never arise? Why should we contemplate choices to be made in circumstances we won't encounter?
One might argue it compels us to think. John Dewey said we only really think when we encounter problems. But I doubt he was referring to imaginary problems. Rather, he was referring to problems in life which could be resolved through intelligent thought and consideration.
C. S. Peirce observed that Descartes, when he purported to doubt everything in attempting to determine whether he could be certain of anything, clearly didn't really doubt. Rather, he pretended to doubt that which he clearly didn't doubt judging from his own behavior each moment of his life. There's no real problem to resolve, no real question to answer, when we have no reason to resolve, or doubt.
Wouldn't it be more useful to address problems we face here and now? Why doesn't philosophy, and why don't philosophers, address the actual problems of humanity?
