Thanks John; this is a really important question I will discuss in detail later on.
Because it is a very uncompromising form of individualism, it is easily mistaken for Randianism.
However, it is substantially distinct from Rand (or again, from Austrian economists such as Ludwig Von Mises).
This is because these various figures actually accept a lot of the ‘anthropology’ or ‘science of Man’ that originated in the early (classical) liberal centuries.
I actually would argue that a lot of the views commonly held by ‘libertarians’ or ‘classical liberals’ are not necessarily easily deducible from that one principle I discussed above.
In other words, they have appeared together as part of a ‘complete package.’ But in many cases, it is possible that their coincidence is really a matter of historical fortune, rather than because they genuinely follow from this one principle I have outlined above.
Do you see what I mean? A lot of what is called ‘classical liberalism’ or ‘libertarianism’ is indebted to a certain ‘historical complacency,’ if you will.
