I'm sure there are philosophers who say they don't, but I guarantee you they act as if they do. Even if they don't know anything about electronics, they'd still expect the light to come on when they flip the switch.
That's... not really an argument. Of course everyone has to act pragmatically; we wouldn't even be able to think if we didn't. But that's quite different from establishing the validity of the principle itself.
I was just wondering. Human minds are messed up in 1001 ways, but are there a few rational principles that most people already have down? Of course, the answers to this question are probably so extremely obvious that I haven't even considered them. But I ask all the same.
