Any postulation about the state of the world after the end can only be speculative – and, for Kant, this means that any speculation about the end of all things can only be based on our moral assumptions and prejudices about the world as a human-centric world, a world-for-us. All that remains will be “those principles we have found ruling in ourselves during the course of our life,” which will inevitably determine any speculation about the afterlife, “without our having the slightest ground to assume that they will alter in the future.”104 Extinction is always speculative.
