I believe this is almost synonymous with freedom, which is the ability to do what you whatever you want without interference from outside forces (other people, government, money constraints, etc). I think to me, Liberty takes this concept of freedom but tempers it a bit in that it only pertains to freedom from government interference. So you can have a society full of liberty and yet still have strong property laws and protections.

So broken down to be bite-sized: freedom is the absence of any outside interference on your will, Liberty is the absence of government interference on your will.

My phone also capitalizes Liberty automatically. So there’s that too 😂
