At the end of the movie Collision, Hitchens was asked whether he believes there is “cosmic justice” at the end of time. Hitchens – being somewhat consistent with his materialist worldview – replied that there is none. However, this is not really the right question to ask him, because such a question presupposes that there is such a thing as justice and does not challenge Hitchens to account for justice on his presuppositions.
The question should be not whether there is such a thing as justice whose demands are not satisfied, but rather that in Hitchens' materialist atheism, the world is intrinsically and fundamentally amoral. There is no such thing as "right" and "wrong" inherent in physical processes, and, hence, there is no such thing as justice. Period.
Hitchens – when he attempts to attack Christianity as immoral – is appropriating absolute moral laws which would not exist according to his material atheism.
That was one point Cornelius Van Til made regarding unbelievers – they finance their worldview / philosophy using the borrowed capital of Christian theism. They oppose Christianity by adopting the truths of Christianity. However, such opposition is thereby self-defeating.
When Hitchens attempts to use logic/reason to attack Christianity, he is again using Christian capital to assail Christianity. Logic does not exist in the atheist's world of material monism.
Hitchens' materialist world is not only amoral, it is also a-logical, and a-mathematical. It is impossible to climb the ladder of physicalism -- in which every rung is physical causation via inviolable physical laws – and reach the non-physical “Platonic” heaven of logic and mathematics. Such realities cannot emerge from physical processes. There is an infinite, insurmountable gap.
The alternative, some form of Platonic atheist pluralism (as held by atheist Michael Martin)- in which there are equal absolutely independent ultimates of matter, logic, moral laws, and mathematics - is just as contradictory and incoherent.
Atheism – whether of the material monism variety or a godless pluralism – is irrational belief in the impossible. But more on that another time.
