Hmm..well that's a tough question there Alex. It depends on which theory you choose to believe. I personally like the Weltanschauung theory.
Well, you see the word Weltanschauung comes from a German word which means "worldview" or “world outlook". Weltanschauung is connected closely with the work of Wilhelm Dilthey, who wanted to provide for the human sciences what Immanuel Kant had provided for the natural sciences.
What? What's the Weltanschauung theory?
The Weltanschauung theory is when you asked me for my opinion not because I am seen to have the answer but also because subconsciously or consciously, you know that we won't have the same exact answer because we have experienced different things. Your worldview and mine consist of different experiences, genetics, and demography which is kind of like an always growing filter that you see and interact with the world through.
Ummm... yeah, I'm just gonna Google it where they'll speak actual ENGLISH!
