What's the bare minimum of freedom needed?

Yeah about the only “unalienable” right that I can think of is that you have the right to think your own thoughts. Nobody can really take that away from you (well I guess people can incapacitate or kill you, or drug or torture you to affect your thought processes… so maybe it’s not as unalienable as I first thought).

“Life, liberty and the pursuit of happiness” also seem rather ill-defined to me. Liberty, in particular - what kinds of freedoms are wrapped up in that term?

If I were to try to lay out some fundamental freedoms/rights for a “good” society though, as @Velocity asked, it would probably include:

  1. freedom from unwanted physical harm - I think most societies have laws against physically harming others for good reason, though some societies allow it as a punishment for breaking other rules
  2. right to equal application of the law - I think this is key to a “free and fair society” - no kangaroo courts is the big thing, and lawmakers should strive to write laws that don’t have discrimination baked into them (probably harder than it sounds though)
  3. right to participate in the political process - I think this is not needed for a theoretical “good” or “fair” society (could have a good society with an enlightened despot), but is needed for a “free” society IMO

And rights for which I think significant restrictions/limitations are required, but for which I think societies should have as underlying values:
4) right to own property (basically needed for any form of capitalism - it wouldn’t be needed under pure communism but I don’t think that’s realistically achievable) - I think there are all sorts of limitations that can be put on this right (eg. taxes, etc.) but I think the idea of property is integral to any sort of commerce occurring
5) freedom of speech - this is the trickiest one, as I think restrictions on speech are generally acceptable, but also that a society which, say, only allows certain government officials to ever speak publicly and all other public expression is banned wouldn’t be considered very “free” to me.

I think any society whose laws don’t allow for #1-3 wouldn’t be considered a “free and fair” society in my completely subjective opinion, and I think a society should fundamentally value #4 and 5 even though the application of those would be nuanced. I’m not even sure if I consider freedom of assembly to be a necessity, though I would expect that most societies would have laws that protect it in some form.
