I guess I'll have to be the devil's advocate: if you consider Truth to be only truth if it's a statement that is always true, then saying it's a chair is only a correct opinion at best, not a fact. *
Consider: There is no ultimate universal definition of what a chair is and what constitutes it (Tragically, Webster's is not the ultimate universal arbiter of
what is), so by that definition what a chair is can only be opinion (i.e. an opinion as to what definition of chair is proper to use). In addition, definitions may change over time, making what was true false & vica versa. So correct opinions are all we have left.
It's
correct because it most certainly is a chair by the definition you have chosen to use using, but it's an opinion because "chair" is just a name for something and not something intrinsic to the object itself. Another example is the concept of Day & Night: they're just a perspective on the motion of the earth, and what you see on the surface of the earth is not true for all observers (someone in space might see no such movement at all; to them, the concept is false). But if it's only true for certain observers following certain definitions, it is an
opinion). Truth is something, ah, higher than that, like mathematical, scientific, and philosophical proofs. Sure the means by which you express these might be specific and limited, but the
idea itself is something that is the same for everyone in the universe, everywhere, forever. Infinite applicability within its own defined rules, a statement about
what is.
That is truth.*
*Disregard all of the above if you believe there really
is a single specific objective definition of 'chair', independent of humanity and which exists even if humanity gets the definition wrong.

You must answer this yourself, and post updates/results.
