Economist Karl Widerquist writes of left-libertarianism and libertarian socialism as being distinct ideologies also claiming the label "libertarianism". However, many works broadly distinguish right-libertarianism and left-libertarianism as related forms of libertarian philosophy. Also identified is a large faction advocating minarchism, though libertarianism has also long been associated with anarchism (and sometimes is used as a synonym for such), especially outside of the United States. Anarchism remains one of the significant branches of libertarianism.
Also stated is that libertarianism is attractive because "(1) it provides significant moral liberty of action, (2) it provides significant moral protection against interference from others, and (3) it is sensitive to what the past was like (e.g., what agreements were made and what rights violations took place)." Libertarians generally advocate the maximization of freedom of thought and action with few exceptions. One exception shared by libertarians is that the actions of an individual should not infringe upon the freedom of any other person, a premise believed by many libertarians to be expressed best through the non-aggression principle.
There are right-libertarian (property rights, minimal or no central government) variants and left-libertarian (“commons” and communitarian) variants as well as minarchists who advocate a minimal state and anarcho-capitalists who believe nearly all government functions can be privatized. The central unifying concept of libertarianism is the conviction that decisions should be made through reason rather than faith or ideology per se. Libertarians themselves overwhelmingly fail to follow this standard competently.
The critique of the libertarians in this blog will be conducted along these topical lines:
Libertarians have the wrong heroes; the ideal exemplars are profoundly inconsistent
Libertarians are astoundingly stupid about human nature, specifically, the human personality
The proof is their awesome deafness to the grand masters of human nature
Libertarians quarrel among each other to the point of babbling and incoherence
Libertarians do not understand power at all; therefore they deserve none
Libertarians talk about reason and logic but are amateurs at logical argumentation
Libertarians know nothing about the wise application of power
coming from wisdom literature
coming from game theory
coming from new forms of logic (such as contract bridge bidding conventions)
The Libertarian philosophy is dangerous and potentially ruinous to civilization
Libertarianism is directly responsible for the greatest non-warfare crisis in human history*
As this crisis developed, libertarians were easily co-opted, manipulated, and herded like cattle
* an amazing accomplishment for so small and quarrelsome a group
CONCLUSION: Libertarians cannot preserve Quiddity
