It’s not only beauty but truth also lies in the eyes of the beholder because one man’s fabrication is another’s fact and vice versa. However, truth differs from beauty in that it is very ugly. I’m not sure if these two can ever cohabit. Beauty occurs where there is symmetry and ‘organisation’ whereas truth only emerges when organisation breaks down.
Could truth be the opposite of beauty? Or a precursor to it. It appears truth can only be defined and searched for within a specific context which is why some argue that there are no universal objective truths. Beauty on the other hand can be universal but I have never experienced truth where there is unaccidental beauty.
