Since I’m fairly certain I’m being ignored now, I’ll leave aside the snark and just address the meat of the last arguments.
Reality as determined by reason and science is not based upon shared consensus. It is based upon results. The consensus is formed after any number of people all perform the same experiment, and return with the same result. We cannot be certain that everyone experiences the color red in the same way, but we do know that “red” can be taught and identified. Since color is a function of light, then the fact that everyone but the color-blind, (who also can be defined with a specific set of tests), will agree that “red” is “red” (IE a specific set of wavelengths processed by the human eye and brain) we can be certain of the reality of the experience. At some point, the numbers game must win out in our perception of reality. The personal and wildly varying realities of the schitzophrenic do not reveal a higher truth or deeper reality. They cannot be shared by others. They cannot be shown to have any objective worth, or physical resemblance to the shared reality. They do not then have validity as truth.
The consensus stems from the proof, not the other way around. Religion makes the mistake that you are accusing us of. It presupposes the answer and then shoe-horns everything else into position; no matter how much we have to twist, cram, or torture the logic to get there.
Just because I can make something taste like a banana through a complex series of chemical compositions does not make that flavor less tasty or enjoyable. Just because I can fool my eye with a rapid series of still images into the illusion of motion does not discredit my ability to use my eyes. The fact that I and millions of other people drive cars about everyday and do not crash through illusory buildings is a pretty good demonstration of that. I can look at a picture of a plant in a book and then identify it from among others in the nursery.
As to your point about art and music, I cannot help but take some small level of offense at your assertion that secular art or music is lacking because of it’s nature. As a classically trained artist, I can tell you with great conviction that art is perhaps the most subjective experience in the human condition. We all experience each piece differently, and it is the triumph of the creator if their message is clear enough to generate a shared experience across a great many people. Indeed not all art and music is created equally nor meant to be. At best your position is a personal preference, at worst it is nothing more than shallow-mindedness.
Where you see the hand of god, I see the elevation of the hand of man to it’s highest purpose. Where you see divine inspiration, I see the craftsman’s touch. The years of training, practice, refinement, and attention to minute detail. You might hear the voice of angels; but how much more meaningful, how much more triumphant to hear instead the voice of man raised in song, putting aside his baser, meaner nature to revel instead in melody, harmony, beat, color, line, mass, and form! To a divine being this accomplishment means nothing. As an achievement of man, it is monumental.
