there is a choice to make

The world is irreducibly complex.

Post-modernism didn't go far enough in rejecting the meta-narrative. Much of our view of the world is based on meta-narrative fallacy leading to utterly useless prescriptive generalisations.

For example;
We are sometimes implored to reduce our 'food miles'; that is, the distance our food has to travel to get to us. The reasoning is simple - we can reduce greenhouse gas emissions by not transporting food further than is necessary. However it is often the case that growing tomatoes out-of-season costs more (in carbon emissions) than shipping them from a country in which they are in season.

Ergo, moral prescriptions like 'eat locally to reduce greenhouse gas emissions' are based on a view of the world which is so simplistic as to be absurd. If one wants to reduce greenhouse gas emissions, the only moral principle they can derive for such a purpose is 'eat foods which have had the least greenhouse gas emissions used in the production and transport'. Irreducible complexity, by definition, defies simplification.

The world of painstakingly constructed (and, ironically, ever more complex) meta-narrative fallacies super-imposed over the reality of human existence is the biggest obstacle to the project of truly understanding and embracing the absolute absurdity of life.
