Is everything only defined by how we come to know it?

Sometimes I wonder who the first person decided this was wrong and this was right.

Or this is good, this is bad. And so on..

In truth if I had kept a person’s view of life skewed they would never draw conclusions for them self. Least only what I would show them.

Though that is not to say simply if I did lift the veil and attempt to bestow them with my beliefs, that the person may not agree, believe, or have his/her own opinion.

More so than anything as the point I am trying to make is what is that spark? The turning point in which one decides this?

Where does this thought come from? Why would it exist if indeed I only give a person only one option if you will or even taught them a certain way from birth.

Why would it even be needed to greater extent, if its purpose only conflicts with things, does that not go against the idea of survival?
