Theory of Knowledge 1

I have a class, Theory of Knowledge, and our first homework assignment was to respond to the word "Why". This is my response.
(I added the rest in)

I hate to disassociate myself so easily so early on, but humans are explicitly known for their inherent curiosity. The almost perverse interest in the unknown propels man forward, keeping his brain ticking and boredom at bay.
But other than in things like space and microscopic particulates, which we cannot physically experience (to an extent), where does this interest come from? Shouldn’t everything else be plainly laid out for individual interpretation? Therein lies the problem. The source of “why” is in assumption.
You can continue to ask ‘why’ for an extended period of time, starting with a simple statement. “We’re going out for a drink.” “Why?” “Because we’re celebrating.” “Why?” “John won the lottery.” “Why is that worth celebrating?” “Because he got a lot of money.” “Why are we celebrating that?” "Because money is something good- it makes us happy.” “Why does money make you happy?”
You could see where I was going with that. At the point where it says, “He won the lottery,” we take up the assumption that winning money is a good thing-something worth having a drink over-we don’t explore the basis behind that. We just take it for what it is. If we went further, like in the dialogue, we’d find the root of the situation, and the unknowns/ambiguities behind it. Hence, “why” is a result of assumption.
Depending on the situation, "why" can be a form of either distraction or immersion. Distraction, in that the situation is so far gone that the concept of "why" is unimportant (eg. running over your neighbor's dog). The reason for the action is, at that particular stage, trivial. All that matters is taking care of the situation as a whole. Asking 'why' then becomes a way of avoiding repercussions: a quick escape route from reality.
"Why" can also be a way of immersing oneself in a subject. This is the more common reason behind seeking reason; to try and understand what has happened/is happening so it can be prevented or encouraged in the future. (Or perhaps that's what we all like to believe is our motive; unwilling to admit that we're voracious information-beasts who swallow and swallow but rarely tend to digest)
Ignoring the numerous tangent-like arguments over the use of "why", it's prevalence in human action in unequivocal, and the quintessence of curiosity.
