In Fyodor Dostoevsky’s The Brothers Karamazov (1821-1881), a story of four brothers in Russia is a grim description of the reality of what the world would look like if God were not to exist. One brother, Ivan, an atheist, tells another brother that there are no objective truths, specifically that there are no moral absolutes. Ivan’s brother then kills his father, an act that obtains no condemnation if God does not exist.
This can be understood as ☐(~Eg ⊃ ∀ϕ~Wϕ),[1] also known as Karamazov’s Theorem. It is necessarily true that if God does not exist then any action cannot be wrong. It may also be true if a conjunct of rightness is inserted into the theorem. This ultimately leads to moral nihilism—a nonexistence of value. Without God, everything is permitted. Nothing can be praised and nothing can be condemned. This world, as Dostoevsky understands it, is a world of nothingness.
Given the natural order of universe and its cause and effect network, perhaps redemption and reconciliation from absurdity can be found in biology or physics. For example, consider an adult salmon’s biologically given capacity to swim upstream and mate. In this case the end at which the adult salmon’s activity aims is not, or anyway need not be, valuable, it is simply the end with which it was endowed by nature.
