OOOOOH. The Philosophy crew is back in action.
Anywho, here's a quick semi-riddle for you guys. I think that universal nouns don't exist. I don't think there is such thing as a 'tree' or 'computer' or 'fruit'. Anything that conveys a large number of items. Taking the word 'tree' as an example, every tree is different, and words have been made to show specifics. So, the definition of the word is useless.
Who agrees, who disagrees, and does anyone have any other beliefs like this?
