What walks like a duck and quacks like a duck and…smells like a duck, must be a duck. And this place does reek of pussy. Did Buddha1 ever return or …..lightgigantic? Good times…good times.
By inference. We are able to measure, with adequate tools, underlying structures. Of course eventually we need to define substance more accurately and notions of substance as matter dissolve away. Eventually we wind up with the interactions of force and energy. No, subjectivity and objectivity does not enter into it at this point. It is a question of semantics. Subjectivity and objectivity are misnomers in any case, there is only congruence. No. Everything but experience and self are inferred so inference remains a valid method. We must begin with the assumption that other exists. ~Raithere
