Philosophy

I think the second individual would be commenting on the first persons opinion. Do you think the second person might answer 'false'? I think they would say, 'I disagree' which is an opinion of the opinion and not whether the apple taste would be an empirical true or false. The use of the word true in this case is simply cultural vernacular in the English cultural bent. If you were German on the other hand you may very well say 'false' instead of registering an opinion. Opinion has a higher status in argumentation in Germanic culture. They are more likely to require an explanation, to stand firm or specifically state it as opinion. Anyway, true works even though it doesn't represent the number 1 or on.
