What Is the Problem of Induction, and Why Are Christians Uniquely Situated to Answer It?

/ Apologetics, Philosophy / 3 Comments

[A short article originally written for the ILIAD Forum.]

The problem of induction is a notorious philosophical problem concerning inductive inferences; more specifically, whether that form of reasoning is generally reliable or rationally justified. An inductive inference aims to draw a general conclusion from a series of particular observations. For example, if I observe one thousand swans, and every one of those swans is white, I can infer inductively that probably all swans are white, and on that basis predict that any future swans I observe will (probably) be white. Unlike deductive inferences, in which the conclusion follows necessarily from the premises, inductive inferences cannot deliver absolute certainty—for example, the possibility of observing a non-white swan in the future cannot be decisively ruled out—but all else being equal, the greater the number of past observations confirming a general law or pattern, the stronger the inductive conclusion becomes.

Inductive inferences have been widely used in scientific research to discover laws of nature. To take one example, Newton’s universal law of gravitation was inferred inductively from empirical observations of the attractive forces between two masses. We haven’t observed the forces between every pair of masses in the universe at every point in time, of course, so we don’t have direct and infallible knowledge of a universal law. Nevertheless, we have made enough observations to be confident that they are instances of a universal law, and we can make reliable predictions about future events by positing that the universal law holds.

What are Worldviews, and Why Should University Students be Mindful of Them?

/ Culture, Philosophy, Theology / 1 Comment

[A short article originally written for the ILIAD Forum.]

As the word itself suggests, a worldview is an overall view of the world. It isn’t a physical view of the world (like the sight of planet Earth you might get from an orbiting space station) but rather a philosophical view of the world—and not just of our planet, but of all of reality. A worldview is an all-encompassing perspective on everything that exists and matters to us. A worldview represents a person’s most fundamental beliefs and assumptions about the universe they inhabit. It reflects how they would answer all the “big questions” of human existence, the fundamental questions we ask about life, the universe, and everything.

Worldviews matter, in the first place, because everyone has one, although not everyone is aware that they have one. A worldview is as indispensable for thinking as an atmosphere is for breathing. You can’t think in an intellectual vacuum any more than you can breathe without a physical atmosphere. Most of the time, you take the atmosphere around you for granted; you look through it rather than at it, even though you know it’s always there. The same goes for your worldview: normally you look through it rather than directly at it. It’s essential, but it usually sits in the background of your thought.

In What Ways Is God the Foundation For All Knowledge?

/ Apologetics, Philosophy, Theology

[A short article originally written for the ILIAD Forum.]

According to a Christian worldview, God is the foundation of all knowledge simply because God is the ultimate foundation for everything in the most general sense. God is a maximally perfect being and therefore is perfect in knowledge: God knows infallibly and comprehensively every truth that there is to know (Ps. 139:1–16; Isa. 44:6–7; Isa: 46:8–11; Heb. 4:13). Furthermore, God is the creator and sustainer of everything else, including human beings and any other creatures (e.g., angels) who have the capacity for knowledge (Gen. 1:1, 27; Heb. 1:1–3; Heb. 11:3; Rev. 4:11). In other words, our knowledge—like everything else we possess—is a gift from God, and all human knowledge is derivative of divine knowledge. As it has often been said, we have been created by God “to think God’s thoughts after him.” Although from our perspective we regularly discover “new truths” and extend our collective knowledge, human knowledge is never truly original in any absolute sense, but only reflective and reconstructive of God’s knowledge (and even then, in a very limited fashion).

Thus, we might say, the Christian worldview affirms a “revelational epistemology”: all human knowledge is ultimately dependent upon divine revelation. Put simply, we can know truth only because God has revealed truth to us—about himself, about ourselves, and about the world around us (scientific truths, historical truths, and so forth). Christian theologians have often distinguished between two basic forms of divine revelation:

  1. Natural or general revelation, available to all human beings through the natural order of creation and the image of God in human nature. (Gen. 1:26-27; Ps. 19:1–6; Acts 14:15–17; Rom. 1:19–20; Rom. 2:14–15)
  2. Supernatural or special revelation (“the word of God” or “the word of the Lord”) given to specific individuals or groups at various times in history through divinely appointed prophets and divinely inspired scriptures (Deut. 18:15–19; Deut. 30:11–14; Ps. 19:7–11; Ps. 119:105; Eph. 2:20; 2 Tim. 3:16–17; Heb. 1:1–2; 2 Pet. 1:16–21).

Does Predestination Make the Problem of Evil More Pressing?

/ Apologetics, Philosophy, Theology

[A short article originally written for the ILIAD Forum.]

This is a tough question to answer in a short space, not least because it ties together two complex and controversial topics! Let’s begin with some basic definitions. The problem of evil refers to the challenge of reconciling the reality of evil with the existence of an all-good, all-powerful God. If God is all-good, presumably he would want to prevent all evil. If God is all-powerful, presumably he would be able to prevent all evil. How then can God and evil co-exist?

As many Christian philosophers have pointed out, the apparent logical conflict can be resolved once we recognize that God could have morally sufficient reasons for permitting an evil; for example, if permitting that evil were necessary to accomplish some greater good. Thus, there is no inherent conflict between the existence of an all-good, all-powerful God and the existence of evil. This insight points us in the direction of a greater-good theodicy: a more detailed explanation of why God permits various evils within the world, whether natural evils (such as diseases and earthquakes) or moral evils (such as murders and rapes). Christian thinkers have developed and defended a variety of greater-good theodicies, but it’s enough for our purposes here to recognize that such theodicies exist and many of them are complementary (i.e., they can be combined to address a wide range of different evils).

The ILIAD Forum

/ Apologetics, Philosophy, Theology

Readers of this blog may be interested to know about a new online resource, the ILIAD Forum. (‘ILIAD’ stands for Ivy League Informational Apologetics Database.) According to the website:

The Iliad Forum was founded in 2021 by undergraduate students from all across the Ivy League, who wanted to provide an online, accessible, and rigorous database of answers to common questions about the nature and commitments of orthodox Christianity. The Iliad Forum site is intended to be a resource for both Christians and non-Christians, where answers to deep and complex questions and objections can be found almost immediately. Many of the questions that we deal with are tailored to the specific interests of undergraduate students at Ivy League universities. However, we also deal with broader topics, such as Christianity in the job market, philosophical apologetics, and Biblical history.

The website already contains dozens of short articles in answer to a wide range of questions. The articles are written by scholars with expertise in the relevant area, including Vern Poythress, William Edgar, and Scott Oliphint.

I was invited to submit answers to five questions in the area of philosophical theology and apologetics. I gather the articles will be posted on the website at intervals, so I’ll post the links here as they become available.
