Re: Illusion or not?

Ian,
You've responded in a similar fashion before. I actually don't understand what you mean by it, Ian.
What I mean by illusion, is not that the illusion itself (qua illusion) does not exist. Illusions (as meant here, so not in the technical sense it is sometimes employed in perceptual psychology) are real mental phenomena. The only thing is that they don't refer to anything real outside themselves, they give the impression that there is something external, outside the mind which really isn't there. Compare the term illusionism.
I really, sincerely thought that this is how most idealists picture the physical world. If not, please explain as that might be quite enlightening for me.
best wishes,

First of all I should say I certainly don't deny that an external world exists. It is true that my sensory perceptions do not enjoy an ontological independent existence from my self, but nevertheless they are external because they are imposed from without, and I do not have any control over their character save for that afforded by my voluntarily bodily movements.
If I see an apple and this visual appearance of an apple changes in such a way which we would expect a real apple to change as we shift our perspective and distance from the apple, and moreover . . . . .
wow! Just got a phone call from my local public library saying they've just got in the latest Ian Stevenson book on European cases of reincarnation which I ordered
months ago! They actually had to buy a copy

. . .
right where was I?
Yeah, and moreover this visual appearance of an apple changes consistent with how we would expect the visual appearance of a real apple to change, and furthermore when we make appropriate bodily movements we receive the appropriate tactile sensations of what a real apple feels like, and when we eat it we get the appropriate gustatory and olfactory sensations, and moreover it gives the appropriate nutritional value and affects ones body in an appropriate manner, just like a real apple would, then if all this happens what is to be gained by saying the apple is nevertheless an illusion?
Allow me to put it another way. We can say that absolutely everything we every perceptually perceive is an illusion if you like, but if we do this what should we call what we presently call "illusions"?? Surely if I can see, touch, taste and smell an apple, and it does everything that we normally ascribe to real apples, then we should label it a real apple!
The problem here is that you're wanting to ascribe a certain ontological status to the external world in order for us to justify us as labeling it as "real". But I find it unhelpful that our everyday language should be contaminated by our particular metaphysical presuppositions in such a way
