How Does this Stool Help?

So, we've got this three-legged stool. what do we do with it?

For starters, we can now see that we need all three legs for the stool to remain standing - to uphold human dignity.

Common good, subsidiarity, and solidarity form a trinitarian means of assessing and refining an actions ability to uphold human dignity. The more fully each is present, the stronger the upholding of human dignity. Each principle is its own person in upholding the one goal of human dignity. Each interrelates with the other two, yet is distinct from them. We cannot truly talk about one without referencing the others (though it is possible, and even common, to neglect one, generally subsidiarity).

The stool helps because it becomes a tool for dialogue on any given possible social action and how well it actually upholds human dignity. The stool becomes helpful because it begins to show us the shortcomings of the solutions we often advocate in the name of social justice. It becomes useful in that it can challenge us to find new and better ways to uphold human dignity rather than ignorantly supporting actions which actually undermine human dignity.
