The Logical Fallacy of Presupposition /Assumptive Thinking
Whenever a logical fallacy is committed, the fallacy has its roots in Agrippa's trilemma. All human thought (without Divine revelation) is based on one of three unhappy possibilities. These three possibilities are infinite regression, circular reasoning, or axiomatic thinking. This is known as Agrippa's trilemma. Some have claimed that only logic and math can be known; however, that is not true. Without Divine revelation, neither logic nor math can be known. Science is limited only to pragmatic thinking because of the weakness of human reasoning, which is known as Agrippa's trilemma. Assumptive thinking, a form of axiomatic thinking, is one of these three unhappy possibilities.
The logical fallacy of presupposition/assumptive thinking occurs when language is used that presupposes conclusions into the statements without first showing those statements to be true. Presupposition is a sneaky assumption. It is an unstated assumption. Often, you need to dig just to find out what the assumption is. The person who is being irrational is probably not realizing the reason that they don't want to talk about their assumptions. No one likes to expose his or her inner thoughts when they are not rational.
Examples of the Logical Fallacy of Presupposition/Assumptive Thinking
"Yet even as creationists keep trying to undermine modern science . . ."
This is an example of nested presupposition, “Yet” is on the outer edge. Within that is “even.” Within that is “as.” Within that is “creationists keep trying to undermine.” Then, comes what is being protected by these nested presuppositions: “modern science.” This is the big lie that this person didn’t want challenged. Evolution is not science, and it’s not modern. Evolution is merely a story. It is a made up fabrication. It is not science.
“In reality, evolution explains all of the evidence found regarding the diversity of life on Earth, where creationism explains none of it, instead replacing an explanation with ‘God it’, a decidedly non-explanation.”
This comment presupposes what it trying to prove. It is clear circular reasoning. If there were no Almighty God, it would make perfect sense to say that Almighty God could not do anything. However, if the Almighty God is the One Who is now enforcing all of what we call the laws of science and if He is indeed the source of all the laws of logic, wisdom, knowledge and understanding, then what? And, we know, by revelation that the Creator, God Almighty is the only reason for the laws of science. However, this Atheist is using circular reasoning and writing about logic. Yes. Believe it or not, this quote came from a website that is about logical fallacies. Not amazingly, this is typical of Atheists websites (and there are many) that are teaching logic.
“The Bible says that Noah’s Ark landed and about 100 years later the people were trying to build the tower of Babel. There would not have been enough people to do it.”
The logical fallacy here is that arbitrary assumptions are being made. How many people could there have been in 100 years beginning with Noah, his three sons, and their wives? And, more importantly, how many people would it take to build a tower? To say something is impossible, one would have to assume the most generations possible with the greatest number of children possible and the least number of people working on the tower. At that point the argument falls flat as an unsound argument.
