Wisdom is more of a state than a trait
We all know the kind of person who did really well at school but can’t seem to help themselves from forever making bad mistakes in real life. And then there are those characters who might not be surgeons or rocket scientists but have this uncanny ability to deal calmly and sagely with all the slings and arrows of life. We might say that the first kind of person, while intelligent, lacks wisdom; the second kind of character, by contrast, has wisdom in abundance. The assumption in both cases is that wisdom is a stable trait – how much someone has is an essential part of their psychological profile and remains constant through their life.
