Nowadays its so difficult find someone with clear mind, but how do you know you're not mind corrupted? Are we conscious of that? Don't think so.
We are all have answer and explanation for everything but how do we know those concepts we live based on are right?
For me the only answer is the doubt. Doubt is evolution. Let's watch "objetively" the past.
At first people believed the earth was plane. At first people believed the earth was the center of the universe. At first people belived flies appear from the meat and rats from the dirtiness.
What was the thing made them change opinion? the Doubt.
Someone started doubt about those concepts, and started to think rationally.
Empirism it's a good method for explain life,but doesn't meant all theories are an invariable truth. It was so difficult to demostrate that ADN is the one which contain the genetical information. The most of scientist didn't believe at first, because their studios showed was improbable. But what was wrong? those studios or the interpretation and the limitations of the human to still investigating that possibility.
The idea of the end or finish and the lineal concept of history move us to believe in the easy way of things we are facing on.
There's not nothing easy. Let's change . We will evolve
