Don't over-think it.\r\n\r\nIt isn't like half the cultures in the world are 'fine with stealing', therefore calling into question why we *aren't* fine with it; everyone is against stealing!\r\n\r\nWe don't need a theoretical discussion about *why*.\r\n\r\n-----------\r\n\r\n\r\n[The Medium-Difficulty Answer]\r\n\r\nPhilosophers, building on the work of others over centuries, have settled on a 'right to property' as one of the basic rights; we know it because they concluded it.\r\n\r\n\r\n-----------\r\n\r\n[The Truest and Most Complex Answer]\r\n\r\n...would require a PhD in philosophy to explain.\r\n\r\nSome people try short cuts -- claiming the existence of 'natural rights' is popular among some -- but there is always some way to pick them apart.\r\n\r\nThe claims that 'people have a right to property' or 'causing suffering is bad' or even '1+1=2' seem self-evident to us, but if you keep digging deeper-and-deeper it gets harder-and-harder to hold it up against all scrutiny.\r\n\r\nDid you think I was exaggerating with the example: '1+1=2'? I wasn't. In 1910, two men -- both were mathematicians and both were philosophers -- published [Principia Mathematica](https://en.wikipedia.org/wiki/Principia_Mathematica), an attempt to explain -- with no assumptions -- that 1+1=2. If you are interested, you could get it from [Amazon](https://www.amazon.com/Principia-Mathematica-Alfred-North-Whitehead/dp/1603864377/ref=sr_1_1?crid=YLIJNU1AZ5TT\u0026amp;keywords=principia+mathematica\u0026amp;qid=1645136468\u0026amp;s=books\u0026amp;sprefix=Principia+Mathematica%2Cstripbooks%2C473\u0026amp;sr=1-1); it is 680 pages, but that is only the first of three volumes.\r\n\r\nPersonally, I'm fine just taking it as a given.","subreddit_name":"AskALiberal","author":"othelloinc"}]}
