Berkeley thought, famously, _esse est percipi_, and the 'tree falling' example is also mentioned by D. Hume. I'm not sure it can be so easily solved. In a way it compares to the chimera bombinating in the void. I tend to believe that things like "it smells", "it hurts", "it sucks", etc. -- are also subject-relative percepta stratum language, as Fredriech Waismann called it. It does not really make sense that a rose, say, would _smell_ so sweet if there' s no nose around. A bush burning may be different, because it's not necessarily sound-producing, etc. Locke distinguished between primary and secondary qualities. Things like SIZE ('bulk' he called it) are _not_ subject-relative (he thought). But things like "rotten" _are_. Think of it: the whole world divides into the primary and the secondary qualities, even if Locke was wrong about some of the examples. Cheers, JL -- I add "and Popper" since possibly Popper commented on this, etc. ------------------------------------------------------------------ To change your Lit-Ideas settings (subscribe/unsub, vacation on/off, digest on/off), visit www.andreas.com/faq-lit-ideas.html
