If I may, I have developed an approach to justice that follows from the observation within material existence that human beings have no choice but to effect choices (choose among perceived alternatives and take action to bring that choice to fruition). I got that from Warren J. Samuels, who all but defined “social power” as the ability to effect choices. If curious, there is “Beyond Liberalism” here in Medium.
By the way, thanks for the reference to Galbraith’s book. He is one of my favorite authors. I’ll definitely be getting a copy.
