In a non-Everettian context (Hugh Everett) identity may be understood in different ways. Consider David Wallace’s example of the ancient pot (P2). An antiquities specialist informs you that your P2 is the same as P1, a famous pot owned by Emperor Tiberius in ad 30. There is a four-dimensional tube P in spacetime extending from P1 toP2—a spacetime worm. The matter of the tube has certain structural and dynamical connections running along it. If we write P(t) for the contents of P indexed at time t, the specialist’s claim is underwritten by the existence of some structural-dynamical relation R holding, for each t, between P(t) and P(t + δt), with δ signifying a difference or change in time. Each indexed moment along P(t) would simply be a stage of the pot’s existence.
There are two basic philosophical conclusions about the identity of the pot being the same pot. The first is called the Worm View as I’ve previously alluded to. Under this view, P is the pot and P1 and P2 are just different names for the pot (literally, P1 = P2). The second view that the P1 and P2 are the same is the Stage View. The pot appears as an instantaneous three-dimensional object: P1 = P(AD 30); P2 = P(AD 2016). Thus, to say that P1 and P2 is the same pot, it means: P2 is linked to P1 by a continuous chain of R-related pots.

Inference to the Best Explanation Revisited (Our Method of Inquiry)
- When using certain theoretical terms, as in the inference to quarks, the epistemic process cannot restrict explanations to only natural or empirical explanations. If one attempts to strip science of all metaphysical import then material causation is the only sufficient form of scientific explanation. However, this has an unnecessary restriction on science and is incongruent with one’s epistemology (if it is to be robust). The robust epistemology certainly accounts for inferential explanations that are not necessarily required to be material. The epistemic methodology may be identical to a non-scientific context but when this methodology is applied in a scientific context then the explanation is ruled out a priori with no [apparent] justification (hence the removal of efficient and final causation from science). Thus, scientific explanations must not necessarily be material explanations. Remember, by using inferential explanations such as quarks and protons we observer their effects and infer as to what the best antecedent causal explanation may be. It’s an issue over the identity of what antecedent causes could be. (In a normal epistemic process the antecedent may be agency).

Kuhn on Scientific Revolutions and Paradigm Shifts
- Scientific revolutions are here taken to be those non-cumulative developmental episodes in which an older paradigm is replaced in whole or in part by an incompatible new one. Paradigms are incommensurable (no common measure—can we really do that and still talk about different models?). (g. planets)
- “Suddenly the fragments in my head sorted themselves out in a new way, and fell into place together. My jaw dropped, for all at once Aristotle seemed a very good physicist indeed, but of a sort I’d never dreamed possible. Now I can understand why he had said what he’d said, and what his authority had been. Statements that previously seemed egregious mistakes, now seemed at worst near misses within a powerful and generally successful tradition.”
- When paradigms enter into a debate about paradigm choice, their role is necessarily circular. Each group uses its own paradigm to argue in that paradigm’s defense. (This circularity doesn’t necessarily make the arguments wrong or ineffectual.)
- There’s no such thing as paradigm independent data. Interpreting the data is paradigm specific. There is no theory-neutral data. No theory-neutral data ≠ objective knowledge. (Kuhn claimed this criticism was the result of a misunderstanding of him.) He claimed that when a scientific revolution occurs, “The world changes.” (He wanted to apply Scientific Revolutions to the contemporary science of his day but was constantly having to modify his philosophy in responding to critics.)
- Anomalies: The parallax of the angles between stars and the earth every six months. The lack of difference between angles was thought to show a Ptolemaic universe; however, the Copernican view allowed for this by suggesting that the angles were insignificant to their measurements (technological limitation) because the stars were too far away. Anomalies may also simply be ignored or counted as, simply, irrelevant until they build an undercutting consensus.

The Discovery Institute’s next summer seminars are from July 10-18, 2015 in Seattle. I attended the seminar in 2010. Once you’re labeled as an ID proponent your academic career is potentially slowed down or halted, unfortunately. Thankfully, I haven’t had any problems even though I’m still agnostic in many areas concerning intelligent design. I’ve gone on to become a Philosophy PhD Candidate at the University of Edinburgh and a I teach two classes in the philosophy of science as a tutor (academic freedom is written into my contract and have had great support from people within the university in regards to my research: fine-tuning and the ontology of many worlds scenarios). I’ve already outed myself as it’s not hard to find it in a quick Google search (I’m a philosopher so it’s not as academically persecuted).
I have no negative comments concerning the DI’s seminar. In fact, I have more respect for the institute and fellows. There were two concurrent seminars (natural and social sciences [now the CS Lewis Fellows Program]) that interacted with each other on a regular basis and combined on many occasions.

The Borde-Guth-Vilenkinb Theorem states that any universe, which has, on average, a rate of expansion greater 0 that system had to have a finite beginning. This would apply in any multiverse scenario as well. There are four exceptions to the theorem.*
