Solipsism Taken Seriously: The External World, Other Minds, and the Limits of Knowledge

By Quim Aiguafreda

What if the only thing you can know with certainty is that your own experience exists?

Solipsism Taken Seriously explores one of philosophy's most stubborn problems: how can we justify belief in a world beyond the mind?

The book follows the skeptical challenge from Descartes' dreams and evil demon to Berkeley's idealism, Hume's doubts about causation, Kant's attempt to rescue objective knowledge, Wittgenstein's attack on radical doubt, and modern thought experiments involving brains in vats, simulations, and philosophical zombies.

Along the way, it asks deceptively simple questions. Can perception prove the existence of physical objects? How do we know other people are conscious rather than merely behaving as though they are? Does the possibility of being wrong undermine knowledge? And if solipsism cannot be conclusively disproved, does that make it a serious account of reality-or simply an extraordinarily difficult idea to get rid of?

Rather than treating solipsism as a bizarre philosophical curiosity, Solipsism Taken Seriously uses it as a way to examine the foundations of knowledge itself: certainty, evidence, perception, inference, other minds, and the limits of what can reasonably be proved.
