Podcast Interview with Justin Schieber of Real Atheology

Justin Schieber

A few weeks ago, Justin Schieber interviewed me for an episode of the Real Atheology podcast. That episode just dropped. 

RA040: Jeffery Jay Lowder on Philosophy of Religion

"In this episode, Justin Schieber sits down with Jeffery Jay Lowder for a wide-ranging interview. Fans of the show will no doubt be familiar with Jeff's work. From founding Infidels.org and the Secular Outpost to his contributions to The Empty Tomb and his several public debates, Jeff has earned his reputation as a fair-minded and philosophically informed atheist. We discuss the origin of infidels.org, Paul Draper's famous argument from Pain and Pleasure and everything in between."

Two Arguments for the Impossibility of an Omniscient Being


An Impossible (or Penrose) Triangle
Source: OpenClipArt; License: CC 

Version #1

  1. Either God can know what it is like not to know that p or God cannot know what it is like not to know that p. 
  2. If God can know what it is like not to know that p, then God is not omniscient (since to know what it is like not to know that p, there must be some p that God does not know). 
  3. If God cannot know what it is like not to know that p, then God is not omniscient (since there is some p—i.e., (L) or (L*)—that God cannot know). 
  4. (Therefore) Either way, God is not omniscient. 


Version #2


  1. Either God can know what it is like to be finite or God cannot know what it is like to be finite. 
  2. If God can know what it is like to be finite, then God is not omniscient (since to know what it is like to be finite, God must be finite). 
  3. If God cannot know what it is like to be finite, then God is not omniscient (since there is something that God cannot know, namely, what it is like to be finite). 
  4. (Therefore) Either way, God is not omniscient.

Another "Impossibility" Argument Against Theism: The Aseity-vs-Temporal Argument


An Impossible (or Penrose) Triangle
Source: OpenClipArt; License: CC 

The Aseity-vs-Temporal Argument

temporal theism =df. theism conjoined with the proposition, "God is necessarily temporal"

(1) If temporal theism is true, then God is a se. [Premise]
(2) If temporal theism is true, then God is temporal. [Premise]
(3) If God is a se, then God is self-existent, independent, and underived. [From the definition of a se]
(4) If God is timeless sans creation and temporal with creation, then God is not necessarily temporal. 
(5) Therefore, it is impossible for God to be both a se and necessarily temporal. (from 3 and 4)
(6) Hence, it is impossible for temporal theism to be true. (from 1, 2, and 5)

To avoid any misunderstandings, I am merely sketching an argument, not defending it. I claim only that it is valid, not that it is sound.

The Argument from the Psychological Relevance of Logical Laws

Introduction


In his book C.S. Lewis's Dangerous Idea: In Defense of the Argument from Reason, Victor Reppert lists nine presuppositions of rational inference.

1. States of mind have a relation to the world we call intentionality, or about-ness.

2. Thoughts and beliefs can be either true or false.

3. Human beings can be in the condition of accepting, rejecting or suspending belief about propositions.

4. Logical laws exist.

5. Human beings are capable of apprehending logical laws.

6. The state of accepting the truth of a proposition plays a crucial causal role in the production of other beliefs, and the propositional content of mental states is relevant to the playing of this causal role.

7. The apprehension of logical laws plays a causal role in the acceptance of the conclusion of the argument as true.

8. The same individual entertains thoughts of the premises and then draws the conclusion.

9. Our processes of reasoning provide us with a systematically reliable way of understanding the world around us.[1]

Commenting on this list of presuppositions, Reppert writes, "It seems to me that all of these elements of reasoning are prima facie difficult to fit within the framework of philosophical naturalism."[2] Here I want to quickly sketch how I would assess one of Reppert's supporting arguments for that claim.

Two "Impossibility" Arguments against (Craigean) Christianity


An Impossible (or Penrose) Triangle

Introduction


In my recent video assessment of the late Dr. Gordon Stein's opening statement in his debate with Greg Bahnsen on, "Does God Exist?", I described two possible ways of defending the non-existence of something. First, I said that one way to defend a universal negative is to use what I call an "impossibility argument." Second, I said that one way to defend a particular negative is to use what I call an "improbability argument." 

As I explained in the video, there are two caveats. First, I do not claim that these two types of arguments are an exhaustive list of the various argument patterns which might be used to support universal or particular negatives. Second, my names for these argument patterns are not standard. For example, a standard name for one type of improbability argument is "evidential argument." The standard name for one type of impossibility argument is "logical argument." For example, J.L. Mackie's famous "logical argument from evil" argues that God is impossible because theism is logically inconsistent with evil. I don't like that name because it sounds funny to outsiders. Imagine an atheist saying, "I'm going to defend a logical argument for atheism." That invites the question, "As opposed to what? An illogical argument for atheism?" While my names are nonstandard, I think they are more intuitive than the standard argument names and so I prefer my names for that reason.

In this article, I will quickly sketch two impossibility arguments for a particular negative: the proposition, "Craigean Christianity is false," where "Craigean Christianity" means the version of Christianity defended by William Lane Craig.

New Video Series on My YouTube Channel: "The Verdict Is In"

I've decided to launch a new YouTube video series, which I call "The Verdict Is In" (a play on Josh McDowell's famous book, "The Jury Is In").

The first two videos are as follows:

  1. Assessment of Frank Zindler's opening statement in his famous 1991 "Atheism vs. Christianity" debate with William Lane Craig: https://www.youtube.com/playlist?list=PL5QAvmnRlfhbOAr8Aop4_beNmUi2UAimt
  2. Assessment of Greg Bahnsen's opening statement in his famous 1985 "Does God Exist?" debate with Gordon Stein: https://youtu.be/tMlm0Ehz1ZU

Note: I do not intend to release further videos regarding the Craig-Zindler debate, but I do plan to record additional videos for the Bahnsen-Stein debate. Bahnsen's presuppositionalist approach is so unusual that it warrants the extra level of analysis. Plus, I intend to use Stein's performance as a case study in how not to debate.

Asimov's Argument from the Bible for Atheism


Photo from New York World-Telegram & Sun, Public Domain

 

Earlier today, the "Thinking Atheist" tweeted a meme with a quotation attributed to the late Isaac Asimov:

Asimov's statement can be read in two ways. First, it could be an empirical claim: people who properly read the Bible tend to become atheists. Second, it could be a normative claim: people who "properly" read the Bible ought to become atheists. In my opinion, the word "properly" is doing a lot of work here; properly read, Asimov is making the normative claim.

But why believe the claim? 

On Twitter, one person replied to me and suggested that Asimov said "atheism" but really meant "the falsity of Judaism and Christianity." Maybe , but if so that's pretty embarrassing for Asimov. The distinction between "atheism" and "the falsity of Judaism and Christianity" is pretty basic. Even middle schoolers can understand it.

Reppert's Atheistic Argument for Violence


Photo of Victor Reppert

Victor Reppert recently posted the following blog post, which I quote in its entirety.
An atheistic argument for violence:
1) Atheism is true, and so obviously so that religious believers must be insane.
2) Insane people can do outrageous things.
3) The people who promulgate belief in God are putting other people's sanity in danger.
4) Even if we have to forcibly stop them from doing so, we can prevent them from leading other people on the road to insanity, and hence possibly outrageous actions.
5) Therefore, the use of force in the name of suppressing religion is justified.

By What Standard?



 

Sometimes theists will ask atheists the following question.

(1) If you don't believe in God, then by what standard can you label actions (morally) right, wrong, or indifferent / neutral / permitted?

A Modest Proposal for Religion and Morality Terminology: Part 4 (Discovered vs Invented)

Photo of a dictionary page showing the definition of "language"

4. Discovered vs Invented

Having reviewed the terminology to describe the positions that moral sentences are either are (or are not) capable of being true or false, I am now going to explore the philosophical territory under cognitivism. When cognitivists talk about the truth value of moral sentences, it is useful to distinguish between the source and nature of these sentences. Allow me to explain. 

Again, consider the following moral sentences.
  • Do unto others what you would have them do to you.
  • Plural marriage, involving one husband and multiple wives, is acceptable.
  • It is the duty of parents to ensure that their daughters are 'circumcised,' i.e., have their clitoris removed.

By definition, if cognitivism is true, each of those sentences is either true or false. But what makes each of them true or false? Here are two indirect answers to that question.

  • discovered: whatever it is that makes moral sentences true or false, it is something that "we" recognize and which is beyond "our" control.
  • invented: a mind (or something like a mind) decides which moral sentences are true or false.
Each of these two options has two sub-options: one limited to humans and one which includes humans and any supernatural beings which might exist, such as gods and God.
  • discovered by humans: whatever it is that makes moral sentences true or false, it is something that humans recognize and which is beyond humans' control.
  • discovered by minds: whatever it is that makes moral sentences true or false, it is something that minds (or something like minds) recognize and which is beyond their control.
  • invented by humans: humans decide which moral sentences true or false
  • invented by minds: a mind (or something like a mind) decides which moral sentences are true or false.
The distinction between "discovered" and "invented" captures most, if not all, of what philosophers mean when they talk about the "objectivity" or "subjectivity" of "morality" in a purely ontological sense, i.e., what "exists" in reality.[1] But the discovered-vs.-invented distinction has a major advantage over the ontological objectivity-vs.-subjectivity distinction. Even among philosophers who define the terms "objective" and "subjective" in an ontological sense, there is disagreement about how to apply that distinction to God (and ethical theories in which God plays a major role). Some philosophers maintain that "discovered by humans" is a sufficient condition for ontological objectivity, while others insist that ontological objectivity means mind-independent and so "discovered by minds" (including God) is a necessary and sufficient condition for ontological objectivity. In contrast, the two distinctions -- discovered-vs.-invented by humans-vs.-minds -- bypasses that semantic swamp entirely and does so in a way easily understandable by everyone.


Notes

[1] In this sentence, replace "morality" with "social moral system or Socratic moral system."

3. Defining "Truth-Apt" and "Not Truth-Apt"

In Part 2, I suggested that, in place of referring to "morality," it would be helpful instead to explicitly refer to the concept of morality the speaker has in mind. I identified the following two different concepts of morality.

  • social moral system: a set of rules which define acceptable or unacceptable behavior towards other people
  • Socratic moral system: a set of rules which define acceptable or unacceptable ways for living one's life, including situations which involve other people and situations which do not.
The "rules" of a moral system can be thought of as sentences which describe acceptable or unacceptable behavior.  Consider the following non-moral sentences.
  • It is 60 degrees Fahrenheit outside.
  • Ronald Regan was the 40th President of the United States of America.
  • The earth is flat.
All of those sentences have truth-values, meaning that they are the kind of sentences which can be either true or false. We'll call sentences of this kind "truth-apt" or cognitive." Now consider the following sentences.
  • Tomatoes: yuk!
  • Boo on running a marathon!
  • Professor: "For your next assignment, we are going to read Dostoyevsky's Crime and Punishment."
    Class: (groans)
These sentences are "not truth-apt" or "non-cognitive." They are not the kind of sentences which can be either true or false. 

Now consider the following sentences about the moral status of various kinds of behavior.
  • Do unto others what you would have them do to you.
  • Plural marriage, involving one husband and multiple wives, is acceptable.
  • It is the duty of parents to ensure that their daughters are 'circumcised,' i.e., have their clitoris removed.
Cognitivists believe that these sentences are truth-apt. Non-cognitivists, on the other hand, believe they are not truth-apt.

A Modest Proposal for Religion and Morality Terminology: Part 2

Photo of a dictionary page showing the definition of "language"
Source: PXFuel; License: Public Domain 

2. Defining "Morality"

I will never forget the time, roughly twenty-five years ago, when I was talking to a fellow atheist about a moral argument for God's existence. I'll call this other atheist "John." According to John, the moral argument is silly because Frans de Waal, a Dutch primatologist, had refuted the idea that morality needs God in his book, Good Natured: The Origins of Right and Wrong in Humans and Other Animals.[1] I remember scratching my head when John said that. I thought to myself, "But that's not what Christians mean when they talk about morality depending on God." This was the first of countless conversations to come with many people, both theist and atheist, who had different ideas about what the word "morality" means.

In the introduction to his book, Morality and Self-Interest, philosopher Paul Bloomfield provides a helpful overview of the two major theoretical definitions of "morality" at play among philosophers. I want to quote Bloomfield at some length.

The first conception may be thought of as the social conception of "morality". It begins with the question of how one ought to behave toward others. Morality is seen as having a final authority over our lives and the interests of others play a necessary role in the decision procedures we ought to use. Where the interests of others are not at issue, morality does not come into play: there is no morality for an agent stranded alone on a desert island. Thus, on such a view, morality and justice, understood loosely to encompass all fair dealings between people, are often seen to have the same scope. Typically, on this conception, morality requires impartiality, such that agents must not see their own interests, or the interests of their families, communities, etc., as having any special standing whatsoever in the decision procedure that determines what ought to be done. Thus, we see Kantian deontology requiring consequentialism more generally, requiring strict impartiality in the evaluation of the outcomes of possible actions. On some accounts, the strict impartiality may be loosened somewhat by, for example, "agent-centered prerogatives," as discussed by Scheffler (1982), but this loosening must still be justified given standards according to which it would be acceptable for everyone to act in the same way; agents may, to some degree, favor themselves to avoid undue sacrifices that would be required by strict impartiality, but they may only do so according to rules that admit no exception.

The other conception of morality dates back to the ancient Greeks, and takes as its starting point the question, "How ought I to live?". It might fairly be called the "Socratic" conception of morality (see Plato's Gorgias, 500c; Republic, 344e). Answering this question will inevitably require one to consider how one will behave toward other people, but extends beyond that, to every significant aspect of a person's life, however private. Thus, someone stranded alone on a desert island may be faced with moral questions, given the possibility of living as well as possible in those trying circumstances. Like the social conception of morality, the Socratic conception of morality will have final authority over the agent's life, representing the agent's "rule of life". As such, the Socratic conception may be seen as formally egoistic, since one begins by aiming at living well, though it need not be substantially egoistic if one determines that one must treat others well in order to have a well-lived life. ... Given the Socratic conception of morality, however, and in contrast to the social conception, rabid, selfish egoism still represents a form of morality, however mistaken it may be.[2]

I have found Bloomfield's summary of these two conceptions of "morality" to be very helpful. Rather than trying to define "morality" per se, which (per Part 1) is sure to be ignored, I propose the following two terms.

  • social moral system: a set of rules which define acceptable or unacceptable behavior towards other people
  • Socratic moral system: a set of rules which define acceptable or unacceptable ways for living one's life, including situations which involve other people and situations which do not.

I do not claim these two terms represent all of the possible options for what other people might mean by the word "morality," but for my purposes they are enough.

1. The Problem

Based on literally hundreds of conversations with people about topics related to religion and morality, I'm leaning in favor of the idea that semantics is a huge obstacle to successful conversation. Allow me to explain. Notice that conversations about religion and morality tend to use some subset of the following words.

  • morality
  • ethics
  • normative
  • prescriptive
  • values
  • obligations
  • duties
  • ought
  • objective
  • intersubjective
  • subjective
  • intrinsic
  • extrinsic
  • theism
  • atheism
  • naturalism
  • materialism
  • God
  • Christianity
  • material
  • Platonism
  • basis
  • foundation
  • realism
  • anti-realism
Even among professional philosophers, there is no universally accepted definitions for any of the above words. To make matters even worse, discussions about religion and morality often use various combinations of the above words. Here are some examples.

  • ethical nonnaturalism and ethical naturalism
  • moral realism and moral anti-realism
  • moral objectivism, intersubjectivism, and subjectivism
  • ontological objectivity and epistemological objectivity
  • objective morality and objective moral values
  • intrinsic value vs. extrinsic value
If even professional philosophers do not agree on the definitions of the key terms in discussions about religion and morality, this would lead one to predict that nonphilosophers do not, either. This is exactly what one finds. Try discussing whether "morality needs God" on social media and you will quickly encounter people using different definitions for the same words. 

It is impossible to have meaningful communication, as opposed to the illusion of communication, if no one can agree on what they key terms in the discussion mean. So, how to address this?

In the past, I have tried stipulating definitions in conversations, but in my experience that hasn't worked very well. Inevitably, people forget or ignore the stipulated definitions, causing the discussion to revert back to the "illusion of communication" problem. For this reason, I'm starting to think we need to adopt a new set of words, ones without any baggage, in order to achieve real communication. What follows is my modest proposal to improve the possibility of real communication.

Swinburne's Free Will Theodicy for the Holocaust

In this post, I want to critically assess Christian philosopher Richard Swinburne's theodicy for the Holocaust. I think his theodicy is of philosophical interest, for three reasons. First, I think Swinburne is one of the greatest, if not the greatest, natural theologians of the 20th-century. Second, Swinburne is an evidentialist and Bayesian; he shares the same general epistemological framework used by Paul Draper, who is one of the greatest, if not the greatest, atheist philosophers of religion. Third, Swinburne has not only written a book-length defense of Christian theism against the argument from evil, but has explicitly offered his theistic explanation for the Holocaust. For these three reasons, then, Swinburne makes a perfect foil for my evidential argument from the Holocaust

Reply to a (Sunni) Islamic Theodicy for the Argument from Pain and Pleasure

In reply to Paul Draper's evidential argument from pain and pleasure, a self-identified Sunni Muslim proposed the following theodicy:

T*: God exists, and God uses human pain to purify the soul.

"In even a prick of the finger, the Muslim has sins wiped away from him and in such pain as if he is made anew if he has actually taken the Hadith of the Prophet any further than his own lips. So while it may not fully fulfill the purpose of detection of threats or illnesses, it does its job in relation to the Islamic framework assuming its truth."
In order to evaluate this theodicy, we should apply Draper's Weighted Average Principle (WAP). I will assume that readers are already familiar with this principle; readers who need an introduction may consult my explanation in section 3.3.2 here. I will argue that this Islamic theodicy does not significantly raise Pr(O | theism) for two reasons. First, I will argue that Pr(T* | T) is not high. Second, I will argue that Pr(O | T*) is not high. 

My Reply to the "There is No Such Thing as Evil if God Doesn't Exist" Objection

I inserted this into my most recent update to my essay, "The Holocaust is Strong Evidence Against Theism," but I'm reposting it as a standalone blog post to draw attention to it.

For roughly 30 years, I have been skeptical of the idea that Euthyphro-style dilemmas provide a decisive refutation of theistic metaethics. I have finally started to organize my thoughts on this topic. 

The link below is to an incomplete draft of an essay I've been writing about Euthyphro-style dilemmas against theistic metaethics. Any comments would be appreciated.

UPDATE (16-March-2022):

In response to the excellent feedback from Jason Thibodeau (see the comments below), I have slightly revised the draft. Version 2 of the draft may be found here:
