We use the word “logic” quite a good deal, it is something we strive to live in harmony with. In its original form, “logic” is simply the study of how to make correct inferences from known truths. If A is true, then so is B.
Logic has many different branches of study, including propositional calculus, predicate logic, and modal logic. It has applications to mathematics, computational problems, and even philosophy. Many of our technologies today, such as the modern database, are based upon its principles.
Another way to explain logic is that it is the study of relationships between truths. Take for example the statements “Adam is the father of Seth” and “Seth is the father of Enos.” By these two truths we may logically infer that “Adam is the grandfather of Enos.” In fact, by being given only a smattering of relationship facts, logic can be used to recompile entire family trees, defining numerous relationships between every member.
And all of this works…until a lie is introduced to the system. It has been proven that a single lie can totally break down any logical system. By process of elimination, one can prove or disprove anything. You could simultaneously prove that Adam is the father of Seth, that he is the mother of Seth, that he is no one to Seth, and that Seth is actually his father. And you can also disprove all of those statements, too. In a word, everything becomes “relative.” Where before you could go to a system of truth and find verifiable fact, now all that remains is a shrug of the shoulders and a “maybe.”
This happens to us in our lives as well. Each of us is born with a very simple model of truth. We inherently accept principles of love, faith, and goodness. It is a small core of truth, but it is sufficient. As we go through life we discover new facts, accepting those that seem to fit with our already-establish model, and rejecting those that do not.
However somewhere along the way, each of us will make a mistake. It is very easy to do. Perhaps a trusted authority figure gave us a notion that we accepted without a second thought. So we added a falsehood, but we believed it to be a truth. We may not realize that anything is amiss for a while, but over time, that lie will corrupt our previous associations. We’ll start to notice logical contradictions in our beliefs, and finally we’ll know that our system has become untenable.
Sadly, many will throw the entire thing out at this point. The work of pruning out the lies from the truth seems impossible. They will claim that there never really were any truths to begin with. It can be a hard thing to let go of a misconception about God without letting go of God entirely.
But that is not the only option. Sometimes evolving our beliefs is a matter of going back to basics. We realize that we went astray, so we return to what few facts we really do know: that we are a child of God, that He loves us, that there is such a thing as “good.” It might be a much smaller belief system, but it will be true again. Then, with utmost care, we add back in only the parts that fit with this core.
