That is if you believe in Objective Truth.
I can say that 1+1=2 and that might be the case, but does that refer to reality?
I can say that the temperature is 40 degrees out, but does that refer to reality as well?
Are these just not systems created by us?
Does Objective Truth exist? On the contrary does Subjective Truth exist?
Do they both not exist and are actually just concepts? Could there be no objective and subjective truths?
