What logical fallacy assumes that the truth of the conclusion can be determined solely based on the argument’s structure?

The logical fallacy that assumes the truth of a conclusion can be determined solely based on the argument's structure is known as Argumentum ad logicam. This fallacy implies that if an argument is flawed in its logical structure, then the conclusion must also be false, regardless of the actual content or evidence presented.

This fallacy highlights the misconception that a valid logical form guarantees a true conclusion. In actuality, an argument might have a valid structure but still lead to false conclusions if the premises are not true or if they do not support the conclusion adequately. Thus, understanding this fallacy is important for critically evaluating arguments, as it emphasizes the need to analyze both the structure and the content of the reasoning rather than relying solely on the form of the argument.
