Well not really, I'm not thinking of just humans but of any being or thing that exist. What is the point of its actions if there is no aim. It's like, lets say I have a child just to have a child, then what? I have child and that's it. Not for support, not for comfort, only to have a child to say I have one. Does it make me happy? doesn't matter, I don't care, I just wanted a child for the sake of doing so. See without aim in any action, an action as serious as this seems pointless or stupid.Or take the world or universe, its here, now what? If there is no aim at what its use is for then the world/universe is pointless and all things that live in it are pointless, useless, living for naught.
Going back to the word "thing."I believe there has to be a set definition for the word "thing" or all our words are meaningless. For example, if you tell a child to observe something and they ask you" What is it?" you would use the word thing in your description because the child is ignorant, but if the child ask "What is thing?" or even more naively "What is an it?" then we wouldn't be able to answer because for now we have no definition. And I don't mean just the English word for "thing" but of any language which has a common base word, for lack of another term. See the aim of all our words are to describe something and they are also used to describe other words but the word "thing" cannot be described by other words but only by observation. This means there is no set definition, if there was then we could describe it using other terms.
