Sorting the Argument from the Conclusion

I've mentioned this before, but one thing a bit of training in analytical philosophy does is teach you to differentiate a good argument from an argument that reaches a conclusion that you like. Once you learn to do that, you become amazed at how often people judge arguments by their conclusions: The argument from the idea of universal human rights makes the case against slavery, therefore it must be a good argument! Hoppe's argumentation ethics advocates libertarianism, therefore it's a good argument! Furthermore, it seems remarkably easy for people to think that if you reject an argument, you reject the argument's conclusion. But that does not follow at all: For instance, Bob Murphy and I wrote our critique of Hoppe's argumentation ethics at a point we both heartily endorsed his conclusion: We just didn't think the argument for it was any good. I think that some readers experienced similar difficulties with my recent critique of Daniel Dennett. One comme...

I Am Learning to Levitate!

"It's true. I am well on my way. I can show you." (You come to my house.) "OK, Gene, let's see." "There you go!" "But you didn't rise at all: what are you talking about?" "Well, I have to start somewhere! The first step is "zero levitation": where else did you expect me to start? But now that I've made the first step, we can see how the process will proceed." "That's ridiculous! No levitation is not the 'first step' on the way to levitating: it's not a step at all." "No, my man, it's you who are being ridiculous. I just learned from a famous philosopher that building a machine 'without the least smidgen of understanding' is an important first step in showing how understanding arose. You see, even though that step didn't get anywhere at all towards artificially creating understanding, it was still a very important step! So I admit, my first step to l...

Does My Thermostat Know That It Is Cold? (More Dennett)

Daniel Dennett and I are kicking back, watching game seven of the Heat-Thunder series (I am in denial) and I say to him, "My thermostat must be feeling chilly." "What are you talking about?" he asks. "Well, it just turned the furnace on: it does that whenever it feels chilly." "That's ridiculous! It's a totally unfeeling machine. Its turning the furnace on is just a mechanical response to the thermometer moving." "OK, then, how do you explain how humans feel hot and cold?" "Ah," he responds, "that is trivial: all you have to do is wire together a whole bunch of mechanisms like your thermostat into a very complex network." Now, there is a pretty obvious logical difficulty here: If the thermostat has zero feeling, how is putting a whole bunch of them together result in a non-zero amount of feeling? As I recall, even trillions of zeroes added together still amount to zero. Now, there is at least o...

Humans Beings Can Be Constructed from Sticks, Straw, and Old Clothing!

You don't believe me? Well, I put up a scarecrow in my field, and some birds thought it was a person. We could even say it is "sorta" a person, couldn't we? At the very least, we are well on our way to constructing a person from sticks, straw, and old clothing, aren't we? And we certainly have shown that it is feasible, even if we can't quite do it yet, right? What is the point of an argument so obviously silly? I'm not sure, but here is what is essentially the same argument , presented by a "philosopher"! Dennett notes, quite correctly, that "Turing realized that [understanding] was just not necessary: you could take the tasks [human "computers"] performed and squeeze out the last tiny smidgens of understanding, leaving nothing but brute, mechanical actions. In order to be a perfect and beautiful computing machine, it is not requisite to know what arithmetic is." But Dennett goes on to claim that these machines, withou...
