Is it reasonable to believe that others have sentient minds?

Asserting that "I have conscousness but no one else does" has a degree of implausibility similar to that of geocentrism: why, out of all of the (more or less) externally similar human beings does ...

Why isn't extreme solipsism the valid interpretation of quantum mechanics?

Extreme solipsism isn't a valid interpretation because you can do experiments where you're not the one observing. Observers don't have to be conscious; they just have to be entangled with the ...

Are consistent solipsists limited to the singular when referencing themselves?

Are there any philosophical arguments to disprove or weaken solipsism?

Not a rebuttal, because solipsism is unfalsifiable anyway, but in On Certainty, Wittgenstein shows that in order to survive solipcists have to act hypocritically. Although they will profess they have ...
