Think about it this way. Have you ever in your life seen intelligence? No. Intelligence is always behind. Never in front. All we see is the result. Never the cause. Can your ears hear themselves? Can eyes see themselves? Can intelligence be understood? Where do our thoughts come from? Do we see the factory where the thoughts are made? Where do we go to when we sleep or do we cease to exist?
Analysis and dissection however seemingly explanatory simply begs the next question in line - Why? Not "how" which might just be the preserve of science but - why?
The purpose of your life is to discover your cause. And the clock is ticking and it never stops.
