At best it motivates me to remain open to arguments that there might be more kinds of 'truth', which I am. But the mere argument that there might be is not interesting, unless someone can provide an argument for a concrete example.
You should study more history of ideas; once you see several examples of seemingly-unsolvable philosophical problems that were later solved by intellectual paradigm shifts, you become much less willing to believe that a particular problem is unsolvable simple because we currently don't have any idea how to solve it.
I don't believe a problem is unsolvable. I don't see a problem in the first place. I don't have any unsolved questions in my world model.
You keep saying I should be more open to new ideas and unsure of my existing ideas. But you do not suggest any concrete new idea. You also do not point to the need for a new idea, such as an unsolved problem. You're not saying anything that isn't fully general and applicable to all of everyone's beliefs.
