Humans invented anthropogenic moralism in order to establish a framework for interacting with each other and with the rest of the planet. This is why we have a moral diversity, because nature is diverse and humans are products of this.
Moralism has however, become largely anthropomorphic and in my opinion this is the greatest moral challenge of our time. We place our highest values on consumption of the natural world without empathising with the implications of this consumption for other forms of life.
If moral absolutism exists, and I think it should, it would be focussed on establishing a true value system that incorporates the impact the entirety of a product’s production chain has on life, rather than simply focussing on the human desire for the final product.
We have been given every indication that our consumption based model is morally absurd as it destroys life, and the ability of the planet to maintain life.
And yet we are increasingly devoted to it as our morals are corrupted to embrace the values of; Lust, Greed, Sloth, Wrath, Pride, Envy and Gluttony.
