Deflect

How is it that we can perceive things that we do not agree with?

Let's take an example.

Why is it that you are doing Xie right now?

You probably don't know what I'm talking about because there is nothing to support Xie in this world.
When we have something that defines Xie then we can imagine all kinds of activities surrounding Xie. Good stuff, bad stuff, etc.

Further:
without the idea of time the... would be no clocks, as we could not imagine the usefulness of such a device.
without the idea of law enforcement there would be no one breaking the laws, because no one could imagine how the laws could be broken.
without the idea of certain religions there would be no sins, because no one could imagine how to sin as "sin" would not be defined.

A clock depends on time, a criminal depends on the law, sin depends on its religion, etc.
However, the opposite is also true. The existence of time depends on time-keeping mechanisms. The law depends on criminals to define it. Religion depends on sin and other aspects of its use in order that it may exist.

Each needs the other in order that it may be defined.

If you were to create a world from scratch and place in it only the "good" things then eventually some of those good things would then turn "bad" in your perception because you need a way to perceive of other things, i.e., to create relationships.

So, we are left with intentionally disagreeing with the things we perceive in order to define the things we do agree with.

[Note: The above is a very simplified explanation of the dependencies of perception. There are a multitude of other factors at play, but the idea is the same.]
