Does Truth Exist?

This seems like a simple enough question, but in postmodern America, it needs to be answered. More and more people are holding to the position that truth is relative, or that two conflicting views can both be true at the same time in the same sense.

Consider the following statements:

These are all statements that people actually say. To refute them, we need to know two rules of philosophy:

The Law of Non-contradiction:
Two contradictory statements cannot both be true at the same time and in the same sense. ("A" cannot be "not A" at the same time and in the same sense)
The Law of Excluded Middle:
Every statement is either true or not true. There is no third option. (Usually expressed as "P or not P")

While people sometimes claim to disagree with these, their arguments on other issues usually assume that these are true. In fact, the whole point of debate is meaningless unless these are true, and it is impossible to disagree with either rule unless it is true. This leads me to a technique that can be used to find flaws in many arguments.

Flawed Arguments

Many statements that people make have an inherent flaw. This flaw is easy to find, and quite comical sometimes. The flaw is that the statement has to be false in order to be true. Although it sounds confusing, this type of flaw can be very easy to find using a technique that is very easy to use. Greg Koukl of Stand to Reason Ministries calls this technique the "Suicide Tactic" in his popular Tactics in Defending the Faith series. Norm Geisler and Frank Turek call it the "Roadrunner" technique in their book I Don't Have Enough Faith to be an Atheist. The technique is to simply apply the claim to itself. This is often best done by asking a question.

For instance, the statement "There is no truth" can be refuted by asking if it is true that there is no truth. See the flaw, now? In order for the statement to be true, there cannot be any truth. But if there is no truth, then even that statement isn't true. Another example that is frequently used is the statement "I can't speak a word in English", which is ridiculous when spoken in English.

All truth is relative.

Is that a relative truth?

That may be true for you, but it's not for me.

Is that statement true for everybody?

All religious views are equally true and valid.

This one is more difficult. In order to refute it, we need to understand what is taught by different religions. For instance, Christians believe that Jesus died and rose from the dead, whereas Muslims believe that he never even died. Logically (based on our two rules mentioned earlier) both statements can be false, but they cannot both be true.

You Kant know the real world.

Then how do you know that about the real world?

It's incredibly arrogant to tell someone that they're wrong.

So if I disagree with that statement, am I wrong?

You shouldn't judge people.

Are you judging me for judging people?
