Base principle: Liberty is inherent and must be optimized
Justice principle: Justice is the foundation of preserving liberty
Safety principle: That which is Just must be made safe
Equity principle: Greater liberty results when equity is achieved
Liberty must be measured and be at the basis of every discussion we have in government. You may ask, "why 'optimized' and not 'maximized?'" Maximized implies that increasing liberty must be achieved at any cost. That leads to sub-optimal thinking that can violate our commitment to non-aggression.
Libertarians are not known for their love of government...but this is certainly an appropriate exception! When we are seeking liberty-optimization, there must be a justice in place that ensures liberty is not being infringed upon.
When we are safe in our person and possession, we are free to pursue greater liberty. Ensuring those who seek to take liberty do not succeed is essential.
Liberty is severely stunted when individuals do not have the means to provide for human necessities - food, shelter, clothing, and medicine. When equity is achieved, liberty flourishes.
