Beyond Science: Understanding Real Knowledge

In previous articles, I looked at how many people make the mistake of assuming that science is the only way we can know something is true. We showed how this view, known as scientism, must be false since it is self-refuting. This time, I thought we'd look at the idea of how we know that we know anything at all and how to better understand the differences between knowledge and beliefs.

Types of Knowledge

Philosophers have spent a lot of time on understanding what it means when we say we know this or that. In their book Philosophical Foundations for a Christian Worldview, J.P. Moreland and William Lane Craig identify three basic types of knowing. The most basic type is knowledge by acquaintance which is simply that you have had some type of direct experience with an object or idea and therefore know it to be true. The authors offer an example of "I know the ball is in front of me." Because the ball is directly present in your conscious experience, you can confidently know that statement to be true. 1

A more debated aspect of this type of knowledge is basic mathematic statements and logical deductions. Some philosophers argue that we know 2+2=4 in the same sense that we know a ball is in front of us. It is directly perceived as true. You don't have to go out and observe 2+2 in different environments around the world or around the universe to confidently hold that he product will always turn out to be 4. We understand that it just is that way. Similarly, we experience the same type of understanding when we argue in this way: All men are born. Socrates was a man; therefore Socrates must have been born. That is a logical argument, but we know it to be true directly.

A second way we know something is through know-how. Know-how defines certain skills or abilities one may possess. When someone claims "I know how to play golf", they are expressing knowledge of ability. Moreland and Craig point out that knowledge of the laws or mechanics is not necessary to hold this type of knowledge. They write "For example, one can know how to adjust one's swing for a curve ball without consciously being aware that one's stride is changing or without knowing any background theory of hitting technique." 2

The third type of knowledge is what is usually debated the most. Known as propositional knowledge this type of knowledge deals with statements that make some kind of claim to fact. Statements such as "I know Abraham Lincoln was the sixteenth president of the United States", "I know our Sun is 93 million mionles away" or "I know humans evolved from apes" are all propositional statements.

Justified True Beliefs

One of the reasons propositional knowledge has been debated is because it has been more difficult than other types of knowledge to define completely and accurately. One of the most foundational definitions of propositional knowledge is the concept of "justified true beliefs" that Plato offered in his writing "Theaetetus". Plato said that if we claim to know something, then what we claim must indeed be true. If a claim is not true, then we didn't really know it; we were mistaken. Further, if we claim to know something we must actually believe the claim to be true. It makes no sense to know something but not to believe it. If I say, "I know the ball is on the floor, but I don't believe the ball is on the floor" I've spoken nonsense.

So truth and belief are what we would call necessary conditions for knowledge. For knowledge to exist, they must both be present. However, they are not sufficient conditions for knowing. Many people believe things, and those beliefs may in fact be true, but that doesn't mean they know those things. Take the statement "I know Jones had roast beef for dinner last night." Now, it may be the case that Jones did indeed have roast beef for dinner, and it may be the case that I truly believe Jones had roast beef for dinner, but by making that assertion without any basis, I've just guessed the right answerand thus cannot be taken as knowledge.

In order to truly know something, there must be some acceptable reason to hold that belief. Justified true belief is believing something that is true with good reason. If I claim to know Jones had roast beef for dinner last night because it's a Monday and he always has roast beef on Mondays, and I smelled roast beef coming from his home, I have good reasons to believe Jones in fact had roast beef. That is a justified belief that can be counted as knowledge. If, however, I claim to know Jones had roast beef for dinner last night because I consulted my Magic 8 Ball, that's not knowledge since the reasons I've given are spurious. It becomes the same as guessing.

Knowledge and the Limits of Science

So why does all of this knowledge stuff matter? Because it helps us understand what is real knowledge and what isn't. When looking at scientific propositions, we understand we can know certain things like the speed at which an object falls or what chemical reaction is necessary to produce nitro-glycerin. Science deals with observations of the material world, so these are justified beliefs; we can say we can know such things through science. However, for other claims, such as whether God exists or whether DNA is the proper basis for measuring the similarities between humans and other animals, science has no justification to make claims of knowledge.

You see, science can only tell us facts about the material world. By definition, science has no way of meaningfully commenting on the many other ways we know things. Science can tell us whether a person's heart is beating faster and he is sweating, but it must fall silent as to whether the cause of that reaction is lying or love. Similarly, science cannot tell us about the most unique aspect of humanity, that is the human soul. When looking at propositions such as the existence of God, science has no way of "testing for God-ness". However, I can know through reasoning that universe began to exist and whatever begins to exist must have a cause. 3 I can therefore conclude that if whatever exists must have a cause and the universe began to exist, then the universe must have a cause: God. That is a belief that has strong justification for it. It is knowledge that is outside the scope of science, but it is probably a more authoritative basis for knowing.

So, even though popular culture looks to the scientist to tell them "the facts" about all things, science is really woefully inadequate to explain many aspects of reality. Scientists may presupposes certain things like miracles cannot happen or there is no God, and then formulate other theories. But that's not knowledge, that's presupposition. Personal experience, emotions, reason, logic, and revelation all address truth-claims and all can be justifiable in their proper instances. To limit one's self to science in order to gain knowledge is like trying to build a house with only a hammer. A hammer can pound nails, but you wouldn't want to use it to drive a screw and it would be completely useless to cut wood.

J.P. Moreland on Why God Won't Force People Into Heaven

If you were to force people to do something against their free choice, you would be dehumanizing them. You would be saying that the good of what you want to do is more valuable than respecting their choices, and so you're treating people as a means to an end by requiring them to do something they don't want. That's what it would be like of God forced everyone to go to heaven.

If God has given people free will, then there's no guarantee that everybody's going to choose to cooperate with him. The option of forcing everyone to go to heaven is immoral, because it's dehumanizing; it strips them of the dignity of making their own decision; it denies them their freedom of choice; and it treats them as a means to an end.
God can't make people's character for them. And people who do evil or cultivate false beliefs start a slide away from God that ultimately ends in Hell. God respects human freedom. In fact it would be unloving—a sort of divine rape—to force people to accept heaven and God if they didn't really want them. When God allows people to say 'no' to him, he actually respects and dignifies them.

Reaching Your Community by Intentionally Reaching Out (video)

There's a lot of worry in our churches today. Everyone is asking "How can we stop the tide of young people leaving the church?" Even Bible-believing churches have seen a decrease in the number of young people engaging.  But all is not dire.

In our relativistic culture, people generally want to find something that is more meaningful and more solid than the whims of amorphous spirituality that the world preaches. Young people want to take action! In this video I talk about how among Christians, interest in participating in community projects is escalating. That means the Church has a great opportunity to reach out in love, to touch the lives of others, and to show one way Christianity is still incredibly relevant in the world today.

How to Get into Spiritual Conversations - Part 2

A few weeks ago, I wrote a popular post on how to start spiritual conversations (you can read it here.) There, I said that one way to begin discussing spiritual things is to listen and discuss topics where people are already interested, such as a news event or a holiday. Just this week, both the news and social media have been awash in stories about Robin Williams and his recent death. Certainly, thoughts about our mortality and whether there's an afterlife come into play. However, it isn't always best to force such a conversation, especially if the person had strong feelings towards the actor. People need to feel; they need to process difficult news and it would be offensive to jump in and immediately turn a tragedy into a sermon.

That said, once a few days pass, it may be appropriate to speak in more general terms about the cult of celebrity and whether our culture places too much value on the lives of the rich and famous. I remember when Steve Jobs, the founder of Apple Computer, died. The day after his passing, the International Business Times published a story which led with "Steve Jobs is dead, but his legacy will live on for decades to come. It is impossible to overstate the impact his work had not only on the world of technology, but on the world as a whole."1 Time magazine included Jobs in its 2012 list of the 20 most influential Americans of all time.2 Not of the past century, but of all time!

Some of the stories released seemed to treat Jobs' achievements as if they were on par not with Henry Ford but Jonas Salk. Such gushing even caused the popular secular tech site Gawker to publish an article with the title "Steve Jobs was not God."3 Author Hamilton Nolan writes:

"So, Steve Jobs is dead. A tech genius has passed on. Sad. Certainly a devastating loss to Steve Jobs' close friends and family members, as well as to Apple executives and shareholders. The rest of you? Calm down.

Among my Facebook friends yesterday, more than one wrote publicly that they were "crying" or "can't stop crying" or "teared up" due to Steve Jobs' death. Really now. You can't stop crying, now that you've heard that a middle-aged CEO has passed on, after a long battle with cancer? If humans were always so empathetic, well, that would be understandable. But this type of one-upmanship of public displays of grief is both unbecoming and undeserved.

"Real outpourings of public grief should be reserved for those people who lived life so heroically and selflessly that they stand as shining examples of love for all of humanity. People like, for example, the Rev. Fred Shuttlesworth."4

For those of you who may not know, Shuttlesworth was a civil rights leader who marched with Dr. Martin Luther King.5 He happened to have died the same day as Jobs, but did anyone hear about it? The New York Times ran the story on Shuttlesworth on page A33, the story on Jobs ran on A1.

Although Jobs made products that many people love and use daily, I can easily picture a world not too different from this one without him. Further, although Jobs at his death was worth $8.3 billion, he didn't have a strong history of philanthropy. Jobs gave some personal donations to area hospitals and to AIDS support, but his gifts amounted to less than 1% of his wealth. Andrew Ross Sorkin even noted that as a company, philanthropy wasn't part of the Apple culture:

While many high-growth technology companies have philanthropic arms, Apple does not. It does not have a company matching program for charitable giving by its employees like some other Fortune 500 companies. The company did donate $100,000 in 2008 to a group seeking to block Proposition 8, a ballot measure that would have banned same-sex marriage in California. But over all, Apple has been one of "America's least philanthropic companies," as termed by Stanford Social Innovation Review, a magazine about the nonprofit sector, in 2007.6

So, in what type of esteem should one hold Jobs? Because he made popular products and had a keen eye for the future, does that merit the level of adulation he received after his passing? Does our culture place too high a value on things and people who make us feel good rather than how they may help others? How does it reflect upon us as a society if people "can't stop crying" after the death of someone they never knew? Does taking the Christian teaching on altruism and selflessness seriously change how people who are successful use their wealth?

There are many spiritual discussions that you can get into in this way. By using an example that's old news, you avoid the "raw" quality of attacking a recent situation but you can still make people think a bit about the reactions they see.

Arguing God's Existence Even When There are No Atheists

Today, Christians can run into many people who doubt God's existence. While books by the New Atheists like Dawkins, Hitchens, and Harris are the most well-known, many "Internet atheists" will comment about the lack of evidence for God's existence or the supposed incredulity of a Supreme Being.

Most Christians who defend God's existence have quite a few different arguments from which to draw upon. Apologists can recount arguments based on the fact that something exists rather than nothing (cosmological arguments), the design evident in creation (teleological arguments), the existence of moral values and duties (axiological arguments), as well as the argument from contingency, the argument from reason, the argument from consciousness, and even arguing that the greatest possible being must exist (ontological arguments).

The amazing thing isn't that as veritable smorgasbord of arguments for God's existence exist within Christianity, it's that arguments for God's existence have existed for millennia, while atheism as we know it is a relatively new phenomenon. In his book, Atheists: The Origin of the Species, Nick Spenser writes that while some of the seeds of atheism had developed through the Renaissance, it really wasn't until ‘the end of the eighteenth century, in which a handful of pioneers, most prominent in France, put forth the first openly and unapologetically atheist arguments since the classical period." 1 Yet, 1200 or so years before Hume and Hébert,  Augustine was offering arguments for God's existence in his On Free Choice of the Will. In the 11th century, Anselm came up with his famous Ontological argument, and during the 13th century, St. Thomas Aquinas wrote his Summa Theologica which included the famous Five Ways arguments for the existence of God.

There were no atheists in Christianized Europe during the Middle Ages. There may have been people branded as heretics and there were definitely many different faith traditions, but no one was actively pushing the non-existence of God. So why would some of the most famous collections of arguments for God's existence be written then?

The answer is simply that Christianity has always been a faith based on evidence. Jesus commanded us to love God with not only our hearts and souls, but with our minds as well. Paul also instructs Christians to "test everything; hold fast what is good." Christianity is built for intellectual inquiry. It should be no surprise, then, that Christians such as Augustine, Anselm, and Aquinas would explore questions of God's existence even if there were no atheists to object to their claim that God does indeed exist.

Frederick Copleston, in commenting on Aquinas' arguments makes an interesting observation:

To us indeed living in a world where atheism is common, where powerful and influential philosophies eliminate or explain away the notion of God, where multitudes of men and women are educated without any belief in God, it seems only natural to think that God's existence requires proof… St. Thomas, however, did not live in a world where theoretic atheism was common, and he felt himself compelled to deal with not only early Christian writers which seem to imply that knowledge of God is innate in man, but also with the famous argument from St. Anselm which purports to show that the non-existence of God is inconceivable.2

Copleston says that Aquinas was arguing against other Christian writings, examining them and calling them out where he felt they were deficient. He was providing some intellectual checks and balances as it were. The fact that intellectual Christians would scrutinize their own teachings and offer rebuttals or counter-evidence demonstrates that leaders like Aquinas were interested in the truth.

Socrates is famously quoted as saying "the unexamined life is not worth living." Christianity is not an unexamined faith. It has been examined not only by its detractors, but by its proponents as well. It is probably one of the most scrutinized worldviews in all of history, yet it continues to offer a complete and cogent understanding f our world.

So the next time you hear an argument against God's existence, don't fear. Chances are it has been examined carefully by Christians already, and found wanting.
