Logical Fallacies: Argument from Final Consequences


Introduction

Continuing my series on logical fallacies, this post will address the fallacy of the Argument from Final Consequences.

What is the “Argument from Final Consequences?”

The “Argument from Final Consequences” fallacy can effectively be stated as: “Something exists, therefore [this] caused it.” In other words, it confuses cause and effect, starting with an effect and then assuming a cause.

Main Example from Creationism

One of the best astronomy/physics-related examples of this logical fallacy from Creationism (and Intelligent Design) proponents is the apparent fine-tuning of the universe. Since I have addressed this argument in detail in a previous post, the very short argument goes as follows: “In order for us to exist, the universe has to be very fine-tuned in order for that to happen, therefore God (or an “Intelligence”) was the one that created it.”

If we deconstruct that argument, we have an observation and conclusion of an effect — the universe must be fine-tuned for us to exist here — and then we have the cause — God did it. In other words, we have the effect placed before the cause in the argument, or an Argument from Final Consequences logical fallacy.

A more honest ay of addressing this situation is to observe that we exist the way we do because of the way the universe is. We have the cause — the universe is the way it is — and the effect — we exist as we do to take advantage of the physical laws of the universe that we inhabit. Saying that we could not exist if the universe were different is probably true, but that does not mean that no type nor form of life could exist, just our particular kind of life.

Final Thoughts

The Argument from Final Consequences is a little harder to spot in discussions because you generally have to pause, deconstruct the argument, and really look at what they’re claiming to be the cause and effect to determine if they are using the effect to justify the cause.
