An argument is, by definition, an exchange of differing views. These views include a premise which supports a conclusion.

# Inductive Arguments

An inductive argument asserts that the conclusion is supported by probability by the premises. For Example: The U.S. budget is the largest in the world and it has been for some time so it will continue to be for at least ten more years. This is inductive because it uses current knowledge and an estimation of what the future holds. Arguments that involve predictions are inductive.

For an inductive argument to be strong the premises must be assumed true and the conclusion must be probable.

# Deductive Arguments

A deductive argument asserts that the truth of the conclusion is validated by the logical sequence of premises. Based on the premises, the conclusion follows with certainty. For Example: If A=B and B=C then A=C.

If a premise is assumed to be true and the conclusions follow with certainty then the argument is valid. If an argument is valid it does not necessarily mean it is true. In the argument, all bats fly and all flying animals are birds then all bats must be birds, the premises of all flying animals are birds not true but if it is assumed to be the conclusion is logical and therefore the argument is valid.
