No matter how smart and educated you are, you still need someone to call you out when you're being an idiot.
@DammitMooMoon I think I'd add knowledge to the list as a separate but entangled concept.
I think intelligence is about a capacity for perception - the capacity to conceptualise and abstract - and there are many types of that. Wisdom is about understanding people and drawing from experience, be that your own or someone else's. And knowledge is just information, facts etc.
By those definitions, I certainly know a lot of educated people, who profoundly lack intelligence and wisdom haha. And of course, people who lack an education but have both in abundance.
