VIDEO: The Thomisitic Abductive Cosmological Argument (TACA)

by Max Andrews

November 19-21 was this year’s annual Evangelical Philosophical Society’s conference. I coauthored a paper with Dave Beck of Liberty University. This is the third year in a row I’ve had a paper accepted for presentation at EPS.

Title:  “A New and Abductive Thomistic Cosmological Argument”

Abstract:  Due to advances in cosmology and theoretical physics the origin of the universe is being relentlessly debated. Nevertheless, whether there is one universe or even an infinite plurality of universes, Thomas Aquinas’ argument for the existence of a first cause from contingency circumvents the debate of temporal beginnings to the universe; such as those that are embedded within the kalam cosmological argument. Tensed, tenseless, dynamic, static, endurantist, and perdurantist theories of time will be irrelevant or be peripheral at best. Physical science as a system will always require further explanation, not mere description, and that explanation will always have to appeal to something outside of itself. This is true for any philosophical and/or theological explanation of science. In this paper we will attempt a consilience of Thomas’ argument from contingency and modern cosmology to show that regardless of whether the universe had a temporal beginning, or what the nature of that beginning might have been, it would still be best explained by a first uncaused cause. We will defend Thomas’ notion of radical contingency and argue against a necessitation understanding of Thomas that is often misattributed to him. This metaphysic will be used as a plausible and defensible abductive cosmological argument, which will appeal to the radical contingency of constituents of the universe, and thus take the form of an argument to the best explanation.

A New Cosmological Argument: EPS 2014

by Max Andrews

This year’s Evangelical Philosophical Society Annual Conference will be in San Diego, California, USA (500 Hotel Circle North, San Diego, California 92108). I will be presenting from 0920 to 1000 on Wednesday in EPS Session A4 in Windsor.

This is the third year in a row I’ve had a paper accepted for presentation at EPS (coauthoring with Dave Beck). This paper will help thresh out some of my research concerning the behaviour of natural law as well as methodology in a philosophy of cosmology. In the paper I will be able to examine different cosmological models (primarily multiverse models) and consider the necessitarian vs. regularity debate as well as the metaphysical and modal status of natural law and the ontological furniture of all reality. This is relevant to several sections of my thesis and the peer feedback offered by conferences such as this are vital to have external minds critiquing my proposed models for many universes and, what I believe to be, the radical metaphysical contingency of worlds.

Might Some of Doctor Who actually be Possible?

by Max Andrews

The following is an article my PhD mentor, Alasdair Richmond, wrote for The Conversation

____

As Doctor Who’s 50th anniversary looms, time travel is everywhere – on the screen, at least. Famously, the Doctor can whizz through the years using a “dimensionally transcendental” machine, the TARDIS, and make changes to the past as and when he likes. But what is time travel – and how much of “Doctor Who” might really be possible?

A handy definition of time travel comes from philosopher David Lewis. Lewis says time travel involves a journey having different durations viewed from outside (in “external time”) or from inside (in “personal time”). Suppose you spend five minutes travelling aboard your machine, as measured by (e.g.) your watch and your memories. On arrival, you find 150 years have elapsed in the outside world. Congratulations, you have time-travelled. Five minutes of your personal time has covered 150 years of external time.

Q&A 34: Thomas Aquinas’ Understanding of Creation and Time

by Max Andrews

Question:

Hey Max I have a few questions about your cosmological argument from Thomas Aquinas:

(1) Did Aquinas believe in creation out of nothing?

(2) Did Aquinas believe that the universe existed eternally side by side with God even though it was contingent?

Also, how can be God be timeless on the view that the universe did not begin to exist? If God’s relation to the universe is always present, would that not imply an eternal relation of God with the universe, which would involve time itself? It is difficult for me to make sense of how God could be timeless on this view and not simply temporal.

Thanks,

Ben Williamson

Answer:

Hi Ben,

Here’s the short answers:

1) Yes.

2) I don’t think Thomas would phrase it that way but Thomas is okay with a creation that has existed for an infinite duration in the past–emphasizing the radical contingency.

Classical Electrodynamics and Absolute Simultaneity

by Max Andrews

Below is the abstract from Ben Nasmith’s paper “Classical Electrodynamics and Absolute Simultaneity”. I’m quite pleased to say that I was able to be an official endorser for Nasmith’s paper to arXiv. Please feel free to investigate and enjoy this research.

Maxwell’s equations and the Lorentz force density are expressed using an alternative simultaneity gauge. As a result, they describe electrodynamics for an observer travelling with a constant velocity through an isotropic medium.

Q&A 20: Does God Know Infinite Sets and Can God Learn Anything?

by Max Andrews

Question:

 Max,

I have a question regarding God being all-knowing in light of the impossibility of an actual infinite set.
I assume the following premises:
·         God knows all true propositions of past, present and future.
·         God does not learn anything but has always known everything. If He was to learn something that would imply there was something He did not know, which would mean He is not all-knowing.
·         It is impossible to contain or hold an infinite set because such an action would imply that it is finite instead of infinite.
Are these three premises valid? If they are, does it follow that the number of events in the future are finite? If so, how does that cohere with the belief that we will be in relation with God for all eternity?

The Thomistic Doctrine of Creatio Continuans

by Max Andrews

Traditionally, there are two models for how God preserves the existence of the universe.  The first is creatio originans (originating creation), which suggests that there has been one initial act of creation and God conserves that reality through a temporal duration.  Consider the following definition.

D1. God conserves e if and only if God acts upon e to bring about e’s enduring from t until some t* > t through every subinterval of the interval t –> t*.[1]

Thomas Aquinas de-temporalizes creatio ex nihilo.[2]  Thus, Thomas is not very concerned with divine conservation as described above since he does not offer a tensed version of creation nor does he differentiate between conservation and creation.[3]  Thomas’ model of creatio continuans (continual creation) can therefore be depicted as:

D2. God continuously creates x = def. x is a persistent thing, and, for all t, if x exists at t, then at t God creates x.[4]

Thomas certainly seems to make a commitment to creatio continuans given his doctrine of simplicity (since timeless follows).  However, Thomas tries to have the best of both doctrines by suggesting that God acts within creation and creation was within time yet, in turn, adopt a model of timelessness.  Thomas argues that the creation of things was in the beginning of time.  For Genesis 1 to include, “In the beginning God created heaven and earth” suggests that beginning connotes time.[5]

Time Travel and Bilking Arguments

by Max Andrews

In this chapter (Paul Horwich, “Time Travel” in Asymmetries in Time: Problems in the Philosophy of Science (Cambridge, MA: The MIT Press, 1987), 111-128.) Horwich discusses Gödelian time travel. He defends Gödel’s claim against the objection that time travel, as he envisions it, cannot occur since it would engender anomalous consequences. He then briefly deals with arguments for a Gödelian spacetime, which entails a closed universe and closed timelines. He then defends issues about anomalous changes and bilking arguments dealing with backwards causation. He concludes his arguments with a defense of Gödel’s thesis that there is a real possibility of trips to the spatially distant past (128).

Nothing is in Time

by Max Andrews

J.M.E. McTaggart provides an objection to the A series of time but suggesting that it may be true that past, present, and future are mere illusions of the mind.[1]  McTaggart dismisses the argument’s subjectivity of time by simply defining it out of existence.

McTaggart’s Argument:

1. Anything existent can either possess the characteristic of being in time or the characteristic of not being in time.

2. Anything existent does not possess the characteristic of being in time [due to subjective references, a lack of indexing events from moment to moment or changing, etc.]

3.  Therefore, anything existent does not possess the characteristic of being in time (time is illusory).

The objection to the A series by the subjectivity of the individual mind is not so easy to dismiss as McTaggart seems to do.  With advances in relativity theory this objection may have phenomenological credibility.  Though McTaggart’s rejection of the argument is correct, there are better reasons for opposing the argument of the mind’s subjective relationship to time.[2]
