 The Fallacy of Composition
I am not minimizing the contribution of symbolic logic, which is the purest form of idea analysis when it is used to analyze the forms of an argument (rather than the arguments themselves, which can fall to point-of-view and definitional issues, especially at a certain level of abstraction).
But symbolic logic at its core is a method of determining truth and falsity, whereas idea geometries, in and of themselves, are value free apart from the relative strengths of their designs.
It may not be the minutiae of logical causal strings that connect micro and macro events, it may be the geometry of the physical relationships the causal strings embody.

 Informal Logical Fallacy
An informal fallacy is one that is not formal, that is, it is a type of fallacy in which the content of the argument is relevant to its fallaciousness, or which is fallacious for epistemological, dialectical, or pragmatic reasons.
Also, because content is important in informal fallacies, there are arguments with the form of the fallacy which are cogent.
For this reason, when forms for informal fallacies are given, this is for identification purposes only, that is, one cannot tell from the form alone that an instance is fallacious.
