Socialism

If that's your definition or the location from which you believe I am arguing then I believe we are having two separate discussions a la Voltaire. I am personally fine with theories being well supported by a large body of evidence such as the evolution of man. Now as for evolution as a concept we literally have direct evidence. We can literally watch organisms evolve, typically ones with very short lifespans or else the test will become intractable.

If a concept is not measurable or testable there is no way to determine if it works towards its intended goal or not. The one axiom I've maintained throughout this is the goal is to increase human and environmental wellbeing. We can create measures and test if a concept is bringing us closer to that goal, further away, or has no measurable effect.

It's my belief the core of any political system is to foster wellbeing and that's particularly true for socialism so in that we can test and measure as to ensure concepts are actually creating intended outcomes. If we cannot test or measure then there is no means through which to determine if said policy is fostering wellbeing.
