Advice about the PhD

This post will both talk about what I am doing now and what lessons I learned (positive and negative) in applying to PhD programs. First, I have been accepted into (and in turn I have accepted) the PhD philosophy program at the University of Birmingham (UK). It’s an excellent program in which I will be in the UK for two weeks at a time, once per year. The British model of the PhD is one in which you do not take courses (this is due to particulars of the British education system going back to their high school curriculum), but rather write up a dissertation. I am beginning this program under the supervision of Yujin Nagasawa, starting this September, and I am very excited! My purpose in getting this PhD is to be able to work within the professoriate, where I will try to be a professor on mission, engaging the culture around me and attempting to shape its future for Christ. If you are interested in supporting me in prayer or financially, please follow this link.

What follows is a hodgepodge of lessons I’ve learned, in no particular order; please don’t use only me as a resource in applying for PhD programs.

1.     Apply early

This almost cannot be overemphasized. Because I was quite busy during application season, I honestly didn’t really begin applying at most programs until the week after Christmas. This was a mistake, for two reasons: a) several programs either had their deadlines quickly approaching (by Jan. 1), or else already passed (ahem, Indiana); and b) some schools had financial aid opportunities or partnerships that had deadlines pass, some as early as the end of September! My failure to move quickly may have cost me a place at one of these schools, or financial aid.

2.     Don’t swing for the fences too much

Here’s what I mean by that. I applied to eleven programs, eight of which rejected me. However, these were programs such as FSU, Virginia, Texas A&M, Baylor, and Oklahoma. These kinds of programs often receive record numbers of applications (sometimes over 250!), and often have anywhere from 4-8 spaces available. I’ve often heard that virtually nothing separates the top 20 or so applicants in these situations; it’s a virtual lottery. Perhaps I should have played the lottery a little less often, and went for an “easier” fully funded program. It’s not all luck, however…

3.     Be sure the program is a good fit

By this I mean a couple of different things. First, be sure the program is known for your preferred area of specialization (AOS) within philosophy. If you are really into the philosophy of art, but the school doesn’t talk about that being one of their strengths, that may be a sign the school isn’t a good fit for you. Second, you’ll want to peruse the faculty page to see if there are any professors whose AOS matches yours. If you haven’t already, try to read and become familiar with these professors and their work. Then, politely contact them via their preferred method (often email), referencing their work and your interest in it. Further, in a few succinct sentences, describe the direction of your research (in terms of dissertation, if you have it) or the specific questions you are currently interested in, and ask the professor if he thinks this might be interesting, or if you should apply, etc. Be sure to thank him for even reading your email. Preserve all email etiquette! This all assumes you find a prof with a match. When you do not contact a professor (which I did not do for some schools, since I had so little time), you really don’t know if you’re a match for the school. The hard truth is that if there is not a prof willing to work with you on your questions/project, then you will be rejected. This is especially true in British programs, where your entire application rises and falls, more or less, on whether there is a prof willing to work with you. It is telling that of the three acceptances I received, I had contacted and received some form of feedback from three professors.

4.     Be sure you’re OK with the location

This is a bigger deal than you might think. This is where you’re going to be spending 3-7 years of your life, depending on your situation and school. That’s a long time to be in a miserable location you hate. Your home (both town and place in which you live) needs to be a somewhat safe space for you to relax. If you’re bored to death or stressed out, that’s not going to help you complete your program and be healthy. One school to which I applied, had I been accepted (I wasn’t, so there’s that), would have required a significant adjustment in what I was used to. In some cases, that can be easy to accept; in others, it can be intolerable. With one of my other acceptances, I would have needed to move to the UK full-time. While I would love to do that, I have a family, and I would have needed to be sure they could handle the situation (they probably could). For two concrete examples, being in the middle of Manhattan for some people could be stress-torture, while living in a tiny college town with nothing for miles can give people a cabin fever. The key is to know your location, know yourself (and any family), and be honest about these prospects. If possible, visit the campus and check out area activities. I myself went to the UK this time last summer, and took a train to Birmingham one of those days (that part of the trip didn’t go well for a variety of interesting reasons, but at least I went!).

5.     Know your end goal

Part of what can help you make your decision is knowing what you want to do with your PhD. Overwhelmingly, people who get PhDs in the humanities want to teach. There’s nothing wrong with that; I certainly do! However, it does not always have to be that. You could be in a thinktank, or a consultant, or work for an academic publishing house, or any number of things! Although you cannot guarantee the future, it’s wise to work toward your end goal. For instance, I decided I wanted to be able to work in either a secular or a Christian collegiate environment. Unfortunately, I cannot do that with a PhD from a Christian school or seminary. Further, there are some American schools that don’t like to hire from British schools, either. Nonetheless, I would be comfortable at either type of school with respect to teaching, so I followed Birmingham’s offer. Just know what you’re getting into. There is not much worse in this area than getting a degree only to find out it’s worthless with respect to what you want to do!

6.     Count the cost

This cost-counting is in terms of time, money, and job prospects. We’ve already spoken a little about job prospects, but I should be honest here: if the sole or overwhelming reason you’re considering a PhD is a full-time, tenure-track position at a major research university, you should not do a PhD. Much like getting into the “best” PhD programs, these positions are a lottery amongst even the top candidates. I myself had to disabuse myself of this notion. I am pursuing a PhD because I believe that is what God would have me to do; I want a full-time position, but even if I do get one, it likely will not be tenured, may not be permanent, or may be in a context I didn’t envision. You may have to be willing to go international (I am, at least in principle!), or be willing to look outside of the university (other academic jobs, like publishing, for example). The point here is know that job prospects in the humanities for the dream job are dim. Be sure you understand that and can live with it.

I mentioned time as well earlier. You will likely lose 3-7 years’ worth of job experience (you likely will not have a career-style full-time job during this time) and earnings. Beyond that, you will be making a major investment whose final emotional payout won’t occur for years. Think about that for a minute. Can you go years in delayed gratification for this? Or are you likely to become very frustrated and mentally exhausted, in an unhealthy place? Don’t gloss over this question.

Finally, count the cost in terms of money. Most reputable American programs in the humanities offer full tuition remission and a stipend in exchange for TA-ing and eventually teaching undergraduate intro courses. With few exceptions, if it is an American program that doesn’t offer this, watch out.[1] However, many stipends are very low—some as low as $12,000. If you get involved with this, you need to do a thorough inventory of what this school is going to cost you and for how long. How much will you need to live there? How much will you take home? Are there fees to pay? If single, will finding roommates be easy? How much am I willing to take out in loans? This final question is huge. Student loan debt does not go away, and it’s worth it to evaluate carefully how much total debt of all kinds you have currently before answering that question.

I myself am trying a combination of my own personal funds (jobs), student loans, and fundraising to finance my PhD. We had to set a limit on what we wanted to take out in loans total. Most of all, in this area, be honest with yourself: you’re not going to buy dollar meals in boxes for five years. Having realistic numbers helps paint a picture to help you decide what to do.

7.     Speak to current students

I only did this a few times, and I wish I had done more. Why? First, because if you get in, these are the students who will become your colleagues. What are they like? Are they interested in the same AOS as you? Are they believers also? Second, because current students rarely put on a show. They’re not trying to sell you on the school. They’ll let you know the good, the bad, and the ugly. How long it really takes to get through, whether or not you can work an outside job, how accessible the profs are as supervisors, any nightmare stories, and any positive stories as well. If a student wants to warn me against going to a school for some reason, I am very likely to take it seriously. On the other hand, if a student goes out of her way to tell me her supervisor is excellent and should be considered, I am very likely to respond favorably to that as well.

8.     Know there are biases, Part 1 (Academic Background)

Unfortunately, there are definitely biases that admissions committees have. Your school could have the best accreditation and be well known in your subfield of philosophy. If the admissions committee doesn’t like it, though, it won’t matter. Here’s what I mean: there are some schools that, if you attended any school with the word “seminary” in its name, will not give you the time of day. This is not necessarily an unfounded bias, and isn’t necessarily malicious. I finally asked one school to which I was going to apply if having a philosophy degree from a seminary ruled me out of the PhD program: short story was, yes, it did. I appreciated their candor, and it saved me some time. It did make me wonder, however, if I should have found a tactful way to ask each school before I applied, and see which ones responded that there was such a bias. Bottom line: if you went to a seminary for your qualifying degree, and you want to apply to a secular school, it’s worth asking. You may receive a response ranging from “it doesn’t matter” to “you won’t be admitted here” to “you would need to do a secular master’s first.” Again, it’s just worth knowing before you dive in.

9.     Know there are biases, Part 2 (AOS)

Another mistake I made concerns the AOS. I went into it believing it should be philosophy of religion. I applied the advice given in (3), and searched. If a school had neither the strength of philosophy of religion nor a philosophy of religion professor, I just didn’t apply. Now, what I didn’t quite realize was that philosophy of religion, as an AOS, is extremely minor. That is, it doesn’t tend to get you admitted or to get you jobs. It’s best to pick one of the four major branches of philosophy (metaphysics, epistemology, logic, ethics), or a popular or major area of focus that the school is involved in (such as philosophy of science or philosophy of math). I may have unwittingly eliminated myself from schools I should not have, either by listing philosophy of religion as my AOS or by not applying because I assumed that would be. I have an MA in that area. Thus, I believe I have the strength to have that be a second AOS, while focusing on metaphysics as my primary AOS.

10.  Follow up, but don’t be annoying

Often, schools will tell you around the time you should be receiving notification (but not always). I was fortunate, in that most schools informed us around the timeframe they said they would. Do not contact the school to check on your status before the time they have given you. They are extremely busy, and it’s the academic equivalent of “Are we there yet?” However, if the school has not given you either a date or a timeframe, it’s completely acceptable to call (trust me, email can take days or even a week to be returned) and speak with someone about it. If you’re polite, and thank them for taking the time to help you, they will usually be happy to give you something.

However, some schools just keep telling you that it will be a few more weeks, and when that happens, there is still no decision. I had two such situations out of eleven, and my only advice is to be polite, patient, and persistent. Don’t be annoying, but an occasional email mentioning that you’re “just checking in to see if there has been any decision) is OK—when the timeframe the school has given you has passed. It is OK to let them know that you have other decisions riding on theirs; if they tell you, however, that it will be another week, then give them another week.

Have any other questions about my experience? Have any comments or stories you’d like to share? Do so in the comments below!



[1] I give an exception for my own Southeastern Baptist Theological Seminary and others like it. This is because their programs are designed to allow you to remain in your context, and thus you can work a full-time job to support your family.

God and the Laws of Nature

The laws of nature are what helps keep this universe running the way it should; they keep it running the way it needs to in order for life to happen! So what accounts for these laws? Are they merely descriptive, or prescriptive?

Let us suppose the laws of nature are descriptive. That is, let us suppose that what we call the “laws of nature” are really more like law-like regularities that describe what we observe in the universe, and extrapolate to apply to all corners of it. These descriptions of how the universe operates are always up for revision inasmuch as they reflect our understanding of what goes on. But this raises the question: Why does the universe run according to these descriptions?

Perhaps the answer is that it is one giant cosmic coincidence. And, on atheism, this is exactly what it looks like. What a fantastically fortuitous coincidence that the laws of the universe are what they are! Perhaps, on the other hand, you might be uncomfortable with this mere accident of the laws.

So perhaps the answer is that the laws are not descriptive, but instead prescriptive. That is to say, once we have arrived at a correct description of the laws, we can give a full account of the way the universe must be, given these laws. They really do function more like laws that cannot be disobeyed (And not simply physically—even descriptive views can say this much. Rather, what this is saying is that this is the way the universe ought to be; the laws govern how this universe must have turned out.). But then why think the laws of nature supervene on the universe in this constraining way? It’s not logically necessary that the laws are what they are.


So perhaps, at last, a solution modestly suggested for your review: God is the one who accounts for the laws of nature. This overcomes our uneasy feelings with mere luck, and it gives an account for why the laws actually can be counted on (if the laws are mere descriptions, then at any moment gravity may be upended, or the speed of light may drastically and suddenly change, etc.) while avoiding any unlikely postulations of necessity. The laws of nature: put in place and upheld by God. Perhaps they are even one of the primary ways God upholds the creation in existence!

Quantum Events as an Objection to the Causal Premise

An advantage of blog posts is that we can focus on particular points within philosophy, theology, or apologetics. One of these things can be the kalam cosmological argument, as popularized by William Lane Craig. A very common formulation of his first premise is, “Whatever begins to exist had a cause.” One of the most common rebutting defeaters to that premise is to say, “But quantum events don’t have causes!” Craig usually has, as part of his response, “The virtual particles come from the quantum vacuum, and the quantum vacuum is a sea of energy, and not ‘nothing’.” I think many people are confused at this response, and don’t understand why it’s relevant. It’s my burden in this post to show why it is relevant, and why it means the skeptic’s objection here is the actual irrelevancy.

First, we have to explain what the first premise is actually claiming, and what it is not. This is crucial to a full understanding of the kalam. The “causal premise” claims that if something begins to exist, then it had a cause for its beginning to exist. It does not claim that “Whatever events occur had a cause,” or something like that. Why is this important?

Because the objection is that quantum events do not have causes for those events occurring. Now some of us will see right away the issue: the skeptic is responding to things beginning to exist in terms of events occurring; it’s a category mistake. What the skeptic would need is to be able to say that the virtual particles come into existence and do so from no cause, or from nothing whatsoever. However, the entire point of the quantum vacuum that produces these virtual particles is that it’s just not “nothing,” it is a sea of energy, which is in fact “something.”


So we can see here it’s through the connecting of the dots we do when we understand both Craig’s causal premise and the objection’s claim that we understand the objection is actually irrelevant. Moreover, and incidental to this critique, is the naïve philosophy of science often demonstrated in this objection. The objection assumes an indeterministic interpretation of the empirical data, when the data is actually equivalent with a variety of interpretations—some of which are indeterministic, and some of which are deterministic, and it’s not the data that can tell us which one is right. For all we know, the apparent indeterminacy is merely epistemological—that is, it merely appears to us as though these events have no causes. But beyond this, the whole point is that even if it turns out the events have absolutely no causes, it won’t follow the virtual particles have no causes for their beginning to exist; that cause will be the sea of energy of the quantum vacuum; the particles do come from somewhere.

What Do We Know, and How Do We Know It? Part 2

The first post within this series on epistemology focused on the idea that certainty is necessary for knowledge (which, of course, it isn’t). This next post in our series is going to speak about another common error. This is usually found among skeptics rather than Christians. It’s called “scientism,” and it contains the following idea:

2. All knowledge can only be gained by science or the scientific method.

This is both a naïve and false view for several reasons. First, a clear definition of what counts as necessary and sufficient for science has not been forthcoming. Virtually every definition proposed of science either excludes some things that are counted as scientific or else includes things that would clearly not be regarded as scientific. In any case, no uncontroversial definition of science exists, and if that’s the case, it’s difficult then to demand that all knowledge claims be subjected to science!

Next, scientism is self-refuting. This is because the claim that “all knowledge can only be gained by science” is not itself a deliverance of science. It cannot even in principle be derived from science. It is a philosophical claim that must be either presupposed or else argued for on the basis of solely or mostly philosophical claims. If that is the case, however, then if we assume the principle is correct, then the claim “all knowledge can only be gained by science” is false. If something’s assumed truth leads to its falsehood, then we call that self-refuting.


I have written elsewhere on scientism, and while it is largely not accepted in philosophical circles (or if it is it is greatly modified), one runs into this on your run-of-the-mill atheist types.
