Whereas Leibniz claimed that this is the best of all possible worlds, Schopenhauer calmly asserted that it was the worst. He substantiated this statement by saying that ‘possible’ does not mean what somebody might be able to imagine, but what truly exists and what will endure. Thus, our world is constructed in such a way that it only barely remains afloat: if it were even slightly worse, it would no longer be able to sustain itself. And because a worse world would be unsustainable, it isn’t a possible world, ergo ours is the worst of all possible worlds.
