I am going to take what seems to be an unpopular stance here and stand up for intelligence.
I can understand where the idea comes from that intelligence and arrogance go hand in hand. The people who are the most outspoken about how smart they are give brains a bad name. In my line of work I get the chance to work with some phenomenally smart folks; in my experience arrogance goes hand in hand with insecurity rather than intelligence. Education doesn’t make someone boastful, it just gives them something to brag about when they try to compensate for their perceived shortcomings.
I have often seen the term intelligence parsed into “book smarts” and “wisdom.” Id prefer to propose a definition of intelligence that I like rather than argue about what wisdom and book smarts are. I like “intelligence is the ability to create or recognize ideas or rules that more accurately describe the world that we exist in.”
Truthful ideas tend to stand on their own, not needing a charismatic personality to preach them. I am always wary of those who claim to be teachers but spend more time trying to convince me of their credibility than actually exploring the strengths AND especially weaknesses of their own hypotheses.
Anyway, I realize this may seem like a bit of a semantic argument, and maybe it is… But semantics are important! When we conflate intelligence with the boastful folks who claim to posses it, it changes our perception and makes us shy away from pursuit of genuine knowledge.
