"The problem of other minds is the problem of how to justify the almost universal belief that others have minds very like our own. It is one of the hallowed, if unfashionable, problems in philosophy. Various solutions to the problem are on offer. It is noteworthy that so many are on offer. Even more noteworthy is that none of the solutions on offer can plausibly lay claim to enjoying majority support." - Hanna Wiszniewska

"That other human beings are mostly very like ourselves is something about which almost all of us, almost all of the time, are certain. There are exceptions, among them philosophical sceptics, and perhaps those suffering from some abnormal mental condition. We do not, of course, believe that we always or even mostly know about others' inner lives in detail, but we do not doubt that they have an inner life, that they experience the physical world much as we do, rejoice, suffer, have thoughts, beliefs, feelings, emotions, and so on. But what, if anything, justifies our certainty? Philosophers cannot agree on what underpins this most basic of human beliefs" (via Wildcat) - Hanna Wiszniewska
