Document Summary
Inference - the process that involves reasoning from premises to conclusions. Premises to lead to a conclusion(which is an assumption) for eg. 1. amy has three children: all people who have three children are excellent mothers, therefore amy is an excellent mother. Signs of inference include words like thus, therefore, as a result, consequently. Therefore a cat is a living being: can be valid or invalid(but absolute) For deductive arguments, that deal with absolute assertions, they are either completely logically strong (valid) or completely not (invalid: a sound deductive argument is one that is valid (absolutely logically strong) with true premises. Validity is a type of logical strength: deductive logically strong means it"s valid, but conclusion doesn"t have to be true, it just shows that if premises are true then conclusion must be true. Inductive arguments deal with degrees of probability .
