ELI5: The core principles of Immanuel Kant's philosphy.

I really need a dummy explanation here. I already read the Wikipedia page three times and still don't understand.

Kant answers 3 big questions:


1- what is reality? 


Kant says there's a real world outside of your body. But the way you experience this world (using your senses of seeing, hearing, touching etc.) creates a map, or model, of this outside reality in your mind, which is unique to YOU. Even things like space and time are unique to you. So if you had different senses, like Superman has superhearing, you'd have a completely different model of reality.


2- what should be? (Right and wrong)


This is Kant's most famous contribution (categorical imperatives.) It means when you conclude that something is wrong, it is wrong 100% of the time, under any circumstances, and for everybody. You can't say murder is wrong then justify using it in some situations (capital punishment, war, etc.) It does not change nor does it matter where or when. 


His point is that because your model of reality is unique to you, you can always come up with situations to convince yourself  what you're doing isn't wrong ("it's not stealing if you're starving.") And there would be no sense of morality if enough people do that. The only way that there can be any morality is that right and wrong are universally established.


3- How should society be governed?


So since right and wrong are universal, societies should be governed by a constitution and by the rule of law. Pure democracy (rule of majority) is not the answer, because no matter how many people believe something to be right, wrong is always wrong.
