TheProblemOfOtherMinds

Context: PhilosophyOfMind

We know our own subjective, phenomenological world.

And most of us hold a fairly orthodox opinion about the objective, "view from nowhere", physical world

The problem of other minds is how we can infer from material world to facts about the minds / subjective perspectives within it. How many of them are there? Which physical systems give rise to minds? And why?

Now ... given that the third person view-from-nowhere pretty much excludes my own subjectivity, and I can't see anyone else's. It seems to me that the only line or demarcation I can be sure of between a physical world and a mental world is that between my own mental world and the outer physical world.

By OccamsRazor I should assume that there are no others.

In other words, it seems to me that the only really defensible positions on other minds are Solipsism (that the world gives rise to only one subjective perspective, mine) and PanPsychism (that every countable thing in the physical world has its own mind)
