It is interesting to see how my opinion has changed over the last 5 months. Now I think that it is much more likely that there will be a convergence of philosophies towards a singular Ultimate Wisdom. It may still be wrong, but unless we try to move into that direction, we won’t know what’s actually the case.
The basic idea it to see the philosophy of idealistic utilitarianism as optimization problem. The goal is to maximize utility under the boundary condition that individual freedom is respected.
This poses quite a problem, however, since we are still quite far away from a state in which individual freedom is really fully respected. So, we would probably need to quantify the degree of freedom to find out how far away we are from the realm of full individual freedom.
