Pointlessness of philosophy I was responding to someone else.
I can say you are wrong and provide reasons if I wish to. We can then go back and forth for a while … eventually we can agree upon definitions and how they are used in certain contexts. If we cannot agree on terms then we will miss the spot.
In general our terms are universal enough to allow for meaningful conversations. Sometimes misuse, or alternative uses, will slip by unnoticed.
When it comes to terms like ‘objective’ used in a colloquial sense we have little trouble understanding what is meant. In fields such as epistemology, sciences or fictional stories the term shifts to suit the medium.
Paradigm shifts will disrupt communication as we have to foster new ways to explicate new ideas/experiences.
I will also mention that ‘right’ and ‘wrong’ are prime examples of terms that have universality in one context but not in another. 1+1=4 is wrong, yet when it comes to ethics what is or is not ‘wrong’ can yo-yo back and forth within an individual perspective when new items come to our attention.
If we both see a dog in the street and one of us says ‘look at that dog’ we know what is meant. Objectivity in this sense in an object of understanding.
If you ask ‘what are you doing tomorrow?’ No one will fail to understand. What they can fail to understand are subtle inferences and reasons for asking/stating certain things.
