I've read some authors whose works are held as belonging to personalism.
However while their works elaborated based on principles of personalism, they never clearly explained what the axioms were that personalism bases itself on.
Bowne also held that persons have value (see axiology, value theory, and ethics). In declaring the absolute value of personhood, he stood firmly against certain forms of philosophical naturalism (including social Darwinism) which sought to reduce the value of persons.
So what could be considered the axioms of personalism?
