Deductive arguments are arguments in which there is a conclusion that follows from the premises (assumptions). The types of deductive arguments (which is a type of logical arguments) are:
Syllogism: always has two premises and all three statements are categorical propositions, and each term is happens twice. Example:
All humans are mortal.
Socrates is human.
Therefore, Socrates is mortal.
Hypothetical Syllogism: made of if-then statements. Example: if p, then q. If Q, then R. If R, then S. Therefore, if P, then S.
Disjunctive Syllogism: Involves use of either/or. Example: either A or B. Not B. Therefore A.
Modus Ponens (MP): If A (the antecedent) then B (consequent).
Modus Tollens (MT): If P, then Q, not Q, therefore, not P.
Dilemma: No matter what happens, the conclusion is negative.
The types of deductive arguments include categorical syllogisms (where the premises and conclusion involve categorical propositions), hypothetical syllogisms (involving conditional statements), and disjunctive syllogisms (based on the principle of exclusion). These forms help in structuring reasoning to draw valid conclusions from given premises.
Deductive reasoning is drawing a specific conclusion from general principles or premises that are known to be true. It aims to provide certainty in the conclusion. Inductive reasoning, on the other hand, involves making generalizations or probabilistic conclusions based on specific observations or evidence. It aims to provide strong support for the conclusion without guaranteeing absolute certainty.
Valid. A deductive argument is considered valid when it follows the correct form of logic, even if the premises are not true. This means that if the premises of a valid deductive argument are true, then the conclusion must also be true.
The truth table for a valid deductive argument will show that when the premises are true, the conclusion is also true. It will demonstrate that the argument follows the rules of deductive logic and the conclusion necessarily follows from the premises.

A deductive argument is a logical reasoning process where the conclusion necessarily follows from the premise. If the premises are true, the conclusion must also be true. It is a form of reasoning that aims to provide logically conclusive evidence for the conclusion.

The ontological argument is typically considered a deductive argument. It aims to establish the existence of God by reason alone, starting from the concept of God as a necessary being. It proceeds through logical steps to demonstrate that God's existence is a necessary consequence of His definition.

Deductive arguments are more common than inductive arguments. Deductive reasoning begins with a general statement and applies it to a specific case, leading to a certain conclusion. Inductive reasoning begins with specific observations and generates a general hypothesis.
Inductive reasoning varies from deductive reasoning as follows: 1) inductive reasoning is a reason supporting an argument and 2) deductive reasoning is an argument against an argument.

A deductive argument with two premises is a syllogism in logic. It consists of a major premise, a minor premise, and a conclusion that follows logically from the premises.

A deductive argument should never be characterized as uncertain or probabilistic. It aims to provide a conclusion that necessarily follows from the premises, making it either valid or invalid based on the structure of the argument and the truth of the premises.
A valid deductive argument will have a valid premise and conclusion and a fallacy may be true, it all matters on how you came to the conclusion.
One general principle in the deductive argument of the Declaration of Independence is that all people are created equal and have inherent rights that cannot be taken away. The Declaration asserts that government is established to protect these rights, and when it fails to do so, the people have the right to alter or abolish it.
