Why is there something rather than nothing?. Is the Universe eternal?. Introduction. We’re venturing into some deep philosophy and physics. PHIL/RS 335. Going back to the beginning.. The cosmological argument has its origin in Ancient Greek Philosophy.. We see versions of the argument in the work of both Plato and Aristotle.. There, of course, the argument was not aimed at proving the existence of a theistic divinity, but at explaining the origin of the world.. AS. Background to the Argument. A classical theistic proof for the existence of God. Supports the concept of the God of classical theism (. omni. -words).

By the end of Chapter 2 we had made it to 1840 with the discovery of stellar parallax and correspondingly ridiculously large distances to the stars.. At this point, it is useful to introduce a device, similar to the Evil Genius device of Descartes, known as the Random Alien Test (or RAT). Under the RAT device, an alien spontaneously appears and asks random planetary inhabitants basic knowledge questions about the Universe that any "intelligent civilization" would know. So, in 1840 the RAT question would be:. Recurrence Relations. ICS 6D. Sandy . Irani. Recurrence Relations. to Define a Sequence. g. 0 . = 1. For n . 2, . g. n. = 2 g. n-1. + 1.
