A formal fallacy in logic occurs when the structure of an argument is flawed, leading to an invalid conclusion. An informal fallacy, on the other hand, involves errors in reasoning or the content of the argument, making it unsound.
Informal logic is the study of arguments and reasoning that does not strictly follow the rules of formal logic. It focuses on everyday reasoning, common fallacies, and how people use language to persuade or make decisions.
The three main divisions of logic are formal logic, informal logic, and symbolic logic. Formal logic focuses on the structure and form of arguments, using systems like propositional and predicate logic. Informal logic deals with everyday reasoning and argumentation, emphasizing the content and context of arguments. Symbolic logic uses mathematical symbols to represent logical expressions, allowing for precise manipulation and analysis of logical statements.
Examples of formal logic include propositional logic, predicate logic, modal logic, and temporal logic. These systems use symbols and rules to represent and manipulate logical relationships between statements. Formal logic is used in mathematics, computer science, philosophy, and other fields to reason rigorously and draw valid conclusions.
formal is just study of logic with purely formal content and material is the branch of logic that focuses the content of reasoning.
Formal logic is logic used to examine the form that an argument is presented in. Formal logic looks at the grammar and sentence structure of an argument through a logical approach.
Mathematical logic is a branch of mathematics which brings together formal logic and mathematics. Mathematical logic entails formal systems for defining the basics and then using the deductive power of logic to develop a system of formal proofs.
if is an expression, while iff is a function often with multiple choices.
A fallacy is a flaw in reasoning that undermines the logic of an argument. There are two main types of fallacies: formal and informal. Formal fallacies are errors in the structure of the argument, while informal fallacies arise from issues with the content or context, such as emotional appeals or misleading language. Recognizing these fallacies is crucial for critical thinking and effective debate.
Some recommended books on formal logic for beginners include "Introduction to Logic" by Irving M. Copi, "Logic: A Very Short Introduction" by Graham Priest, and "The Logic Book" by Merrie Bergmann.

Formal logic concerns itself primarily to the correctnes rather than than the truth of a logical process. Material logic on the other hand is the truth of a material content.
