growing knowlege but lacking wisdom

Knowledge or wisdom which is the best,to think your the smartest because you ace every test or to learn from all mistakes made by you and the rest

We find new ways to create and destroy but if we learned from war we would have peace and joy
We all play a part in corrupting young minds but still we can't read our own signs and we've lived through it thousands of times

We started out bad and kept getting worse but its our fault we live in a world so cursed
 
What will it take before we reach the brink ,to finally give the people anew perspective to think.
