Scientific Methods, Semiotics, and Logical Fallacies
Scientific Knowledge and Formal Methods
Formal science does not take into account the experience of events, but rather the forms of reasoning. These sciences are used for authentication in two ways: induction and deduction. Deduction-based reasoning processes derive a conclusion from one or more premises, where the conclusion is a logical consequence of the preceding statements.
Methodological Ideals in Formal Science
In formal science, certain methodological ideals exist:
- Axioms: These are the basic principles of systems, characterized by their availability, productivity, and transformation rules.
- Organization: Complete systems designed to address new questions that arise.
- Theorems: Specific propositions obtained from axioms through the process of deduction.
Methods in the Natural Sciences
Natural sciences utilize induction by checking, which involves drawing general conclusions from private, known cases. There are two types of induction:
- Full Induction: A study of the entire area, taking into account every known case.
- Incomplete Induction: A study that does not cover the whole area or every possible case.
The Theory of Signs
A sign is something that stands for something else to someone in some capacity. Therefore, a sign is not merely a natural object. There are four items to keep in mind regarding signs:
- The subject interpreter.
- The signifier.
- The referent.
- The signification.
Three Types of Signs
- A) Indices (Remains): The sign has a real, physical connection to the designated object.
- B) Icons: The sign has a certain similarity to the object it represents.
- C) Symbols: The sign represents the object without any natural links or direct similarities.
Functions of Human Language
- The Function of Knowledge (Referential): This occurs when the sender reveals something to the recipient. The goal is to describe how things actually are.
- Expressive Function: This is used when the sender indicates their internal state or feelings.
- Conative Function: This takes the recipient into account, aiming to encourage, persuade, or influence them.
Factors of Human Language
- Syntactic Dimension: Concerns the relationship between different signs.
- Semantic Dimension: Concerns the connections between signs and their meanings.
- Pragmatic Dimension: Concerns the connections between signs and the users of those signs.
Common Logical Fallacies
- Complex Questions: These are questions that contain hidden presuppositions. While sometimes appropriate, they can be traps used to confuse an interlocutor.
- Circular Argument: This occurs when the defense of a statement uses the statement itself as a reason. These are failures in logic because they do not contribute to a productive dialogue or prove anything.
- Ad Hominem: This involves attacking the person making the argument rather than the argument itself in an attempt to refute their opinion. It often involves criticizing the interlocutor's alleged defects.
- Argument Based on Authority: Defending a view solely by mentioning an authority figure who shares the same opinion.
- Ad Baculum: The use of threats or force to win an argument.
- Ad Populum: Appealing to the emotions, power, or feelings of a crowd.
- Ex Populo: Using a specific approach to prove a truth based on the fact that many people believe it.
- False Cause: Incorrectly identifying the cause of an event.
- Hasty Generalization: Making a universal proposal based on a single particular case.
- Slippery Slope: Arguing that a small first step will inevitably lead to a chain of related (usually negative) events.
