I do not believe that God is inherently known, or a “properly basic” belief, as the belief in existence of other minds is: Alvin Plantinga argues this, and argues it well, but it is still too much of a Reformed religious epistemology, that is, with presuppositions that reason itself can never
prove, but only
demonstrate, God’s existence: for this reason I can not get behind it. There may be something that drives man to look for the divine; I know not. I do know that
if a man looks for the divine, and has a solid foundation in philosophy, classic or modern - especially classic - the conclusion, the
proof that God exists is inescapable.
I will demonstrate this using a few term-logic syllogisms. Let it be known that I am not using all of the proofs, let along arguments, for God’s existence, nor am I attempting to answer objections that can be made to them (of which I can write dozens of pages, sadly; both objections and rebuttals of the objections, through which I came to the conclusion the defenses were significantly stronger than the objections, and thus came to Theism); if and when objections are made, I will rebut them. I am presenting the arguments in the most simple form I know. I am presenting what is known as Al Ghazali’s Cosmological Proof below, which requires no acceptance of classical metaphysics to remain valid, as does Thomas Aquinas’ First Way, which is the Aristotelian analogy to this. The syllogisms in brackets are not essential to the argument, and are additions designed to answer common objections.
[1) Infinity can never be achieved by adding one finite number to another.]
[2) The series of temporal events is a set formed by adding one event after another.
3) A set formed by adding one event after another can not be actually infinite.
4) Therefore, the series of temporal events can not be actually infinite.]
Thus, with “past infinite” cosmology (whether in the context of chaotic inflation or steady-state model) disproved by the most easy method (in logic, not to mention the evidence of the Big Bang).
[1) The Universe is a series of temporal events.
2) No series of temporal events can be actually infinite.
3) Therefore, the Universe is not infinite.]
[1) Eternity is the actual infinite of time.
2) The Universe is not actually infinite.
3) Therefore, the Universe is not eternal.]
[4) If the Universe is not eternal, it began.]
The actual argument:
1) Everything that begins to exist had a cause.
2) The Universe began to exist.
3) Therefore, the Universe has a cause.
This is one of the four kinds of arguments that convinced me (counting all cosmological arguments, such as Aristotle’s, Aquinas’, Leibniz’s, Ghazali’s, etc. as one kind). I can defend what is called the “teleological argument” as well, and it supposedly converted Anthony Flew to Deism, but I put no stock in the argument myself, nor in any of the arguments based on a preponderance of empirical science instead of pure logic.
For further reading, I recommend
The Wiley-Blackwell Companion to Natural Theology, edited by William Lane Craig and JP Moreland.
The first cause is a philosophical solution to the logical problem of the infinite regress, and to the quandary “Why something instead of nothing?”.
That is the argument from a first cause, and the principle of sufficient reason, respectively. In any case, the “God of the Philosophers” led me to the “God of Faith”, and in the case of some of the arguments - the argument from Pure Actuality, the argument from morality - the two are one and the same. I believe Diagnosis remembers my post in his thread, “Why be spiritual?”, including what I said about “the God of the Philosophers”, Deism, Neo-Platonism, etc. - Christianity being the most logical choice, based on an inductive approach to predicting the shape of reality and true religion based on the attributes of the being shown necessary by the sum total of several different proofs of God - but based on evidence and induction, not deduction - and can interpret within that framework.
The belief in God is not a matter of faith. It is a matter of rationality, of proof. The belief in Christianity, or any specific religion, is a matter of faith, at least to some degree (albeit not nearly the degree that Hume and Kierkegaard would have made it out to be).
PS Aquinas’
Quinquae viae, or Five Ways, will make no sense, or will seem absurd, to someone who has imbibed and taken for a foregone conclusion of truth a great deal of modern philosophy, and has rejected the metaphysics of the ancients, given that three of the five - and the best three of the five - rely on the Four Causes of Aristotle, and a Realist conception of reality. Then again, all knowledge - not just the knowledge of God - falls apart under conceptualist and nominalist conceptions of truth.
