I don't even pretend to know whether other humans have "consciousness" or "agency". I can only perceive my own. My resolution to the "problem of other minds" is a moral choice, and an act of faith. I take it as axiomatic that other humans have these things. Whether in the unknowable truth I am right or wrong, I'm sure this is a good choice. I don't want to be lonely, or a sociopath, even if in fact I could only be those things or not in some solipsistic simulation. 4/
