Why do people disagree about things?

It usually is.

 

They feel that it is wrong, and they feel that it is wrong because it goes against their sensibilities.

 

I can understand disagreeing about things, but it shouldn't be a personal affront. It all boils down to insecurity, I think. We are all frail and blind to the big picture. If you have a strong opinion about something, be a grown up about it; figure out exactly why you are right, explain why as best you can, and that's the best you can do.

 

I assume people only disagree regularly about the more superficial of things- when you think about the collect unconscious however I think people do share unity and will agree over their beliefs in and around more universal concern.

 

There's also the issue of dominance. How big of an issue this is may be a matter of opinion, but I think it's huge. Consciously or subconsciously, the drive to reproduce is so strong that it will outweigh good sense. Often times people may disagree because what they are actually doing is trying to appear attractive to the opposite sex rather than trying to be correct.

 

Were a single consciousness, but reality is filtered in a heterogeneous manner. I think it makes things interesting myself.

 

Why do people disagree.

Because of individual perspective. Whatever you're experiencing, you and only you (on earth) experience it from that exact perspective. No matter how close another individual is to the same basic experience, their perspective is different from yours, no matter how minute the difference.

This is true not just when something notable is happening, it's true every single nano-second of your life, ever and always accumulating, formulating, your psyche, your senses, your wiring.

Only souls at one with all things are in agreement. I'm guessing that's not us.
