Question

why is it that a belief can't be a basis for formal arguments?Explain your answer ​

Answer 1

it is important to stress that the premises of an argument do not have actually to be true in order for the argument to be valid. An argument is valid if the premises and conclusion are related to each other in the right way so that if the premises were true, then the conclusion would have to be true as well.

Answer 2

Beliefs are characterized as "true" or "false" in virtue of the truth or falsity of the propositions that are believed. People can believe propositions with varying degrees of conviction, but believing something does not make it so, no matter how hard you believe.
