Depends on how you use them. Words are developed by people that knew less than what an average person knows now, so how could they be smarter without own consciousness?! 
Even if the same words are used, the wisdom expressed in them is for who reads, understands, lives and reflects it. We learn by example if we don’t have time in life to live the experience, so we are often fascinated by the wisdom reflected in the words of others. Best words are the words of God in the Quran by the way as well as best wisdom. 
Anyways, there are many ways to communicate not only words.
