Some would say so. I've actually thought over this a bit, and that's one of the themes in my story, "The Truth". OK, that title leaves little enough to the imagination
In it, I have a race of people who see truths in everything, or forms, as Plato called them. Everything has its own truth, which it is based on, thus, life is truth. All that is beautiful is
truth, while all that is evil has
truth, albeit of a different kind. According to these philosophies, beauty has truth, but is not specifically defined
as truth. That's a little bit of my own view, there. There is more to truth than just beauty, but there is great truth in beauty as well.
