Why Does Thinking Matter?

We have spent the semester learning about thinking, so the question I'm asking here is, why does thinking matter? According to Arendt, thinking is what allows us to have a conscience, it allows us to be a good person by making us consider out actions from the point of view from the other people it may effect.  It also represents our natural curiosity towards the world. Thinking is what sparks the mind to consider things beyond the everyday, which in turn makes people consider what is out there. Why are these two things important? Because they are part of what makes up humanity as a whole, thinking is what drives us to learn and grow as people, and to treat others well. Thinking is what makes societies change and strive upwards. Thinking is important.
