Why? What is the Reason? What is the Purpose?

“Why” is the question word that asks for the “reason” behind things. However, “reason” can mean both the cause that leads to a specific outcome (Why do objects fall? Because gravity pulls them towards the earth) and the purpose behind a specific outcome that will be fulfilled after its realization (Why did you turn on the oven? Because I want to bake something).

Living organisms seem (to humans) to cause certain outcomes for a “purpose”: They move in order to find food or escape a hunter. They use special signals in order to attract the opposite sex. As they grow, they learn how certain actions lead to certain outcomes and then they do these actions with the purpose of bringing this outcome.

Humans seem (to humans) to do everything with a “purpose”. They have taught themselves how to manipulate all sorts of forces around them. They put seeds in the ground and take care of the plants that grow and then harvest them, instead of looking for plants planted by “chance”, therefore that need to be stumbled upon by “chance”. They build complex structures that can explore the deep oceans, or the deep space.

But there is no “purpose” in the lightning bolt that hits the tallest tree of an area. That’s how lightning bolts are, how they work. The physics behind it dictate that the lightning bolt is created between certain regions of a cloud and of the ground that are oppositely charged. Most often, the tallest mass of the area of the ground is the one that gets hit. Clearly, there’s nothing “personal”. The lightning bolt doesn’t “choose” which tree to hit and doesn’t hit a certain tree “for a reason”.

So, the “lifeless” part of the universe doesn’t exhibit any form of “purpose”. Years and years of science show that the better we understand the world around us the better our predictions about its interactions become. And whenever something “unexplainable” by the current standards comes along, it’s just explained by a few new ideas that we hadn’t come up with until that point.

Our everyday lives haven’t really involved rain chasing a specific person or any lifeless object, defying the rules of physics for some “purpose”. We’ve dropped countless objects and yet not one has hovered to our surprise (magic tricks are only tricks on perception). The driver and the mechanics lead a car. If one “loses” control of a car, the car isn’t acting “for a purpose”.

There is “purpose” in that car accident only if someone involved acted specifically in that way with the intention to bring it about. There is something to be said about the conscious and the subconscious, but that still doesn’t bring in some higher, deeper purpose in the equation.

However, purpose, even when it comes to living creatures, is simply the rationalization our brain has created to fill in the blanks of causality. Observing a human reach for a glass of water, we might argue that the “reason”, with the meaning of “purpose”, of this action is “to drink water”. However, this simply skips the true reason, with the meaning of “cause” this time, for the action: which is, most probably, that the human is thirsty. Therefore, we have very good reasons to think “purpose”, and “reason” when it is implying “purpose”, is simply a biocentristic idea, that has evolved in the brains of a type of conscious creature, floating on a rock in the deep, cold space, otherwise devoid of any teleological “purpose”.
