Do we truly like a certain article of clothing? Or is it just that a person we think is pretty wore it and now we unconsciously like it. But what makes that girl pretty in the first place? Ever sense we were born we've been fed descriptions and images of what a girl or guy is suppose to look like. So is what we think is truly our own opinion, truly ours? Because if ever sense we were born we've never been given a real chance to just look at something, with no background knowledge at all, and just say how we feel about it, or what it makes us think of.
All of our thoughts, judgments, and opinions our based off of someone else's, whether it's disagreeing with someone or agreeing, it's never truly our own. I don't think that we ever will truly get to have a completely genuine experience, of our very own unbiased opinion on anything because the world we live in will always have something to say about it before we do.
So once you except the fact that your opinions aren't truly your own, you must try to swallow the fact that truth itself is a relative term. If all of our thoughts aren't our own, then who truly decides what is true and what isn't.
All in all, the postmodern society we live in, forces us to be okay with ultimate uncertainty, as there is no way to ever truly know what are solely our own ideas. Every single little thing we see or hear impacts how we see the world whether we realize it or not.
