how do i know what i know if i know anything at all?

Throughout the years, people have depended on science and facts to be sure of what it is that is truly known. Others rely on, ironically, the unknown to explain what it is that is true. Allow me to explain. Obviously when it comes to science we've pretty much grown accustomed to believing that such things are true because all of the facts seem to ass up and knowing that gives us a sense of comfort. Others rely on things such as religion. Things that are thought to be true but can never me proved. And that's what it's all about. If it can be proved then it's true. Why is it this way? Science. Basically i stand with the fact that we all know what we know thanks to the facts, or at least what we believe to be facts. Then again it thanks to the fact that society believes these facts. So technically, society is the root of how we know what we know. Not just in the sense of knowing how it is that the world works but society also helps us form ourselves throughout the years. Like Siddhartha we could choose to leave but, essentially, society was the root of that.
