Answer:
3 steps: detachment, syllogism and contrapositive.
Deductive arguments are also evaluated in terms of their validity and soundness.
Explanation:
A deductive argument is one in which the conclusion necessarily comes from the reasons or premises. This means that if the premises are true, the conclusion will also be true, since there is no possibility that it is false. This is the strongest kind of argument that exists, because if we accept the premises, we also have to accept the conclusion. Deductive method is the mode of logical reasoning that makes use of deduction to draw a conclusion about certain premises. The deductive method usually contrasts with the inductive method
. Its possible to verify 3 "laws" (or steps) to see if its about a deductive argument:
- The law of detachment: is the first form of deductive reasoning. A single conditional statement is made, and a hypothesis is indicated. The conclusion is then deduced from the premise.
- The law of syllogism takes two conditional assumptions and forms a conclusion, combining the hypothesis (premises) with the conclusion.
- The law of the contrapositive that in a conditional if the conclusion is false then the hypothesis must be false too
Deductive arguments are evaluated in terms of their validity and soundness. An argument is valid if it is impossible for its premises to be true, while its conclusion is false. In other words, the conclusion must be true if the premises are true.
An argument is sound if it is valid and the premises are true. It is possible to have a deductive argument that is logically valid even if it does not seem to be listening. Fallacious arguments often take this form.
