maturity

I know a young man who is pretty smart. He has recently started using big words in his vocabulary. Big words like epistimology and existentially and stuff like that. What usually accompanies these words are attitudes like arrogance, impatience, and self-righteousness. Knowing big words and big ideas does not mean a person's knowledge is mature. Maturity of knowledge will come when the person can speak of their big ideas with big or little words--and with humility, patience, and respect for others.
