Black Mass: Apocalyptic Religion and the Death of Utopia

Black Mass: Apocalyptic Religion and the Death of Utopia is a non-fiction book by John N. Gray published in 2007. Gray was at the time the School Professor of European Thought at the London School of Economics and in the book he further develops his critique of social progress. In recent history, he looks at the New Right government of Margaret Thatcher and the neoconservative government of George W. Bush. He also connects totalitarianism, that is communism and Nazism, with millenarianist movements in the Middle Ages, citing examples such as that of John of Leiden, who led a rebellion in the German city of Münster in 1534. In here he is helped by the work of Norman Cohn, The Pursuit of the Millennium. His main thesis is that the influence of said religious movements created the secular, Enlightenment belief in social progress. This philosophy of history, known as teleology, has contaminated the contemporary isms, including classical liberalism.

Is God Dead?

"Is God Dead?" was an April 8, 1966, cover story for the news magazine Time. A previous article, from October 1965, had investigated a trend among 1960s theologians to write God out of the field of theology. The 1966 article looked in greater depth at the problems facing modern theologians, in making God relevant to an increasingly secular society. Modern science seemed to have had eliminated the need for religion to explain the natural world, and God took up less and less space in people's daily lives. The ideas of various scholars were brought in, including the application of contemporary philosophy to the field of theology, and a more personal, individual approach to religion.

The Kalām Cosmological Argument is a 1979 book by the philosopher William Lane Craig, in which the author offers a contemporary defense of the Kalām cosmological argument and argues for the existence of God, with an emphasis on the alleged metaphysical impossibility of an infinite regress of past events.

First, Craig argues that the universe began to exist, using two philosophical and two scientific arguments. Second, Craig argues that whatever begins to exist has a cause that caused it to begin to exist. Finally, Craig argues that this cause is a personal creator who changelessly and independently willed the beginning of the universe.

Lectures on the Philosophy of ReligionW
Lectures on the Philosophy of Religion

Georg Wilhelm Friedrich Hegel's Lectures on the Philosophy of Religion outlines his ideas on Christianity as a form of self-consciousness. They represent the final and in some ways the decisive element of his philosophical system. In light of his distinctive philosophical approach, using a method that is dialectical and historical, Hegel offers a radical reinterpretation of the meaning of Christianity and its characteristic doctrines. The approach taken in these lectures is to some extent prefigured in Hegel's first published book, The Phenomenology of Spirit (1807).

Tractatus Theologico-PoliticusW
Tractatus Theologico-Politicus

Written by the Dutch philosopher Benedictus Spinoza, the Tractatus Theologico-Politicus (TTP) or Theologico-Political Treatise was one of the most controversial texts of the early modern period. In it, Spinoza expounds his views on contemporary Jewish and Christian religion and critically analyses the Bible which underlies both. He argues what the best roles for state and religion should be and concludes that a degree of democracy and freedom of speech and religion works best, like in Amsterdam, while the state remains paramount within reason. The goal of the state is to guarantee the freedom of the citizens. Religious leaders should not meddle in politics. Spinoza prepares the ground for his work on metaphysics and psychology Ethics, published posthumously in 1677, for which he anticipated harsh criticism.
