Argument from perpetual identity against naturalism.

[Mystic]

If it doesn't prove it, then whether you have to believe in identity to believe in perpetual identity, it's still properly basic. It's only not properly basic when it is proven by other statements or rather believed based on other statements proving it.

Going back to the example that it's good to appreciate our parents goodness and love towards us, it takes concept of parents (belief in that), belief in goodness, concept of love as well, but it's still a properly basic belief most of humanity has.
